Sunda Shelf
–
Geologically, the Sunda Shelf is a southeast extension of the continental shelf of Southeast Asia. Major landmasses on the shelf include the Malay Peninsula, Sumatra, Borneo, Java, Madura, Bali and it covers an area of approximately 1.85 million km2. Sea depths over the shelf rarely exceed 50 metres and extensive areas are less than 20 metres resulting in strong bottom friction, steep undersea gradients separate the Sunda Shelf from the Philippines, Sulawesi, and the Lesser Sunda Islands. Biogeographically, Sundaland is a term for the region of Southeastern Asia which encompasses areas of the Asian continental shelf that were exposed during the last ice age. Sundaland included the Malay Peninsula on the Asian mainland, as well as the islands of Borneo, Java. The shelf has resulted from millennia of activity and erosion of the Asian continental mass. During glacial periods, the sea level falls, and great expanses of the Sunda Shelf are exposed as a marshy plain, the rise of sea level during a meltwater pulse 14,600 to 14,300 years Before Present was as much as 16 meters within 300 years. Present sea levels submerge a number of Pleistocene Paleo River Systems that drained much of Sundaland during the last glacial maximum 18,000 to 20,000 years ago, to the east of the Sunda Shelf is the Sahul Shelf. Separating these two regions of shallow seas is Wallacea, which encompasses Sulawesi and the thousands of smaller islands making up Nusa Tenggara, within Wallacea lie some of the deepest seas in the world with depths of up to 7,000 metres. Passing between Bali and Lombok, and Borneo and Sulawesi, the Wallacea is marked by a zone of flora. The exposure of the Sunda Shelf during eustatic sea level changes has effects on the El Niño oscillation. W. Earle in 1845 was the first to describe the features of the Sunda and Sahul Shelves, which he termed the Great Asiatic Bank. The Paleo River Systems of the Sunda Shelf are vast submerged river systems that extend present-day river systems, during the driest of the Pleistocene era some four distinct catchment areas form the Malacca, Siam and Sunda River Systems. The Siam River System consists of a northern and a western arm, the northern arm extends the Chao Phraya River to drain the Gulf of Thailand. The Malacca Straights River System is formed by a conflux of waters from Northeastern Sumatra, the Northern Sunda River System, also known as the Great Sunda River System, or Molengraaff River System. Finally the Eastern Sunda River System empties Northern Java and Southern Borneo, Sundaland Sunda Shelf mangroves - Voris, H. and C. Simpson,2000 and 2006, The Field Museum, Chicago, Illinois

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Body of water
–
A body of water or waterbody is any significant accumulation of water, generally on a planets surface. The term most often refers to oceans, seas, and lakes, a body of water does not have to be still or contained, Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. Most are naturally occurring geographical features, but some are artificial, there are types that can be either. For example, most reservoirs are created by engineering dams, similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways, some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term body of water can also refer to a reservoir of water held by a plant, note that there are some geographical features involving water that are not bodies of water, for example waterfalls, geysers and rapids. Arm of the sea - also sea arm, used to describe a sea loch, arroyo - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally. Artificial lake or artificial pond - see reservoir or impoundment, barachois - a lagoon separated from the ocean by a sand bar. Bay - an area of water bordered by land on three sides, similar to, but smaller than a gulf, bayou - a slow-moving stream or a marshy lake. Bight - a large and often only slightly receding bay, or a bend in any geographical feature, billabong - see Oxbow lake, a pond or still body of water created when a river changes course and some water becomes trapped. Boil - see Seep Brook - a small stream, canal - an artificial waterway, usually connected to existing lakes, rivers, or oceans. Channel - the physical confine of a river, slough or ocean consisting of a bed. See also stream bed and strait, earth scientists generally use the term to describe a circular or round inlet with a narrow entrance, though colloquially the term is sometimes used to describe any sheltered bay. Basin - a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, creek - an inlet of the sea, narrower than a cove. Delta - the location where a river flows into an ocean, sea, estuary, lake, distributary or distributary channel - a stream that branches off and flows away from a main stream channel. Draw - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, fjord - a submergent landform which has occurred due to glacial activity. Glacier - a large collection of ice or a river that moves slowly down a mountain. Glacial Pothole - see Kettle Gulf - a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay, headland - an area of water bordered by land on three sides

Sea
–
A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, the sea is the system of Earths salty. The sea moderates Earths climate and has important roles in the cycle, carbon cycle. Although the sea has been traveled and explored since prehistory, the scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. Owing to the present state of continental drift, the Northern Hemisphere is now equally divided between land and sea but the South is overwhelmingly oceanic. Salinity in the ocean is generally in a narrow band around 3. 5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers. About 85% of the solids in the sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature, surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses, former changes in sea levels have left continental shelves, shallow areas in the sea close to land. The most diverse areas surround great tropical coral reefs, whaling in the deep sea was once common but whales dwindling numbers prompted international conservation efforts and finally a moratorium on most commercial hunting. Life may have started there and aquatic microbial mats are generally credited with the oxygenation of Earths atmosphere, the sea is an essential aspect of human trade, travel, mineral extraction, and power generation. It is the scene of activities including swimming, diving, surfing. However, population growth, industrialization, and intensive farming have all contributed to marine pollution. Atmospheric carbon dioxide is being absorbed in increasing amounts, lowering its pH in a known as ocean acidification. The shared nature of the sea has made overfishing an increasing problem, both senses of sea date to Old English, the larger sense has required a definite article since Early Middle English. Seas are generally larger than lakes and contain salt water, while the defining elements of size and being bounded are generally used, there is no formally accepted technical definition of sea among oceanographers. In international law, the United Nations Convention on the Law of the Sea states that all the ocean is the sea. Earth is the known planet with seas of liquid water on its surface, although Mars possesses ice caps

Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

Indonesia
–
Indonesia, officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania. Situated between the Indian and Pacific oceans, it is the worlds largest island country, with more than seventeen thousand islands. At 1,904,569 square kilometres, Indonesia is the worlds 14th-largest country in terms of area and worlds 7th-largest country in terms of combined sea. It has an population of over 260 million people and is the worlds fourth most populous country. The worlds most populous island, Java, contains more than half of the countrys population, Indonesias republican form of government includes an elected legislature and president. Indonesia has 34 provinces, of which five have Special Administrative status and its capital and countrys most populous city is Jakarta, which is also the most populous city in Southeast Asia and the second in Asia. The country shares land borders with Papua New Guinea, East Timor, other neighbouring countries include Singapore, Vietnam, the Philippines, Australia, Palau, and the Indian territory of the Andaman and Nicobar Islands. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support the second highest level of biodiversity. The country has abundant natural resources like oil and natural gas, tin, copper, agriculture mainly produces rice, palm oil, tea, coffee, cacao, medicinal plants, spices and rubber. Indonesias major trading partners are Japan, United States, China, the Indonesian archipelago has been an important region for trade since at least the 7th century, when Srivijaya and then later Majapahit traded with China and India. Local rulers gradually absorbed foreign cultural, religious and political models from the early centuries CE, Indonesian history has been influenced by foreign powers drawn to its natural resources. Indonesia consists of hundreds of native ethnic and linguistic groups. The largest – and politically dominant – ethnic group are the Javanese, a shared identity has developed, defined by a national language, ethnic diversity, religious pluralism within a Muslim-majority population, and a history of colonialism and rebellion against it. Indonesias national motto, Bhinneka Tunggal Ika, articulates the diversity that shapes the country, Indonesias economy is the worlds 16th largest by nominal GDP and the 8th largest by GDP at PPP, the largest in Southeast Asia, and is considered an emerging market and newly industrialised country. Indonesia has been a member of the United Nations since 1950, Indonesia is a member of the G20 major economies and World Trade Organization. The name Indonesia derives from the Greek name of the Indós, the name dates to the 18th century, far predating the formation of independent Indonesia. In 1850, George Windsor Earl, an English ethnologist, proposed the terms Indunesians—and, his preference, in the same publication, one of his students, James Richardson Logan, used Indonesia as a synonym for Indian Archipelago. However, Dutch academics writing in East Indies publications were reluctant to use Indonesia, they preferred Malay Archipelago, the Netherlands East Indies, popularly Indië, the East, and Insulinde

Indonesian language
–
Indonesian is the official language of Indonesia. It is a register of Malay, an Austronesian language that has been used as a lingua franca in the multilingual Indonesian archipelago for centuries. Indonesia is the fourth most populous nation in the world, of its large population, the majority speak Indonesian, making it one of the most widely spoken languages in the world. However, most formal education, and nearly all national mass media, governance, administration, judiciary, the Indonesian name for the language is Bahasa Indonesia or sometimes simplified as Bahasa. This term is occasionally found in English and other languages. Indonesian is a register of Riau Malay, which despite its common name is not the Malay dialect native to Riau. Originally spoken in Northeast Sumatra, Malay has been used as a lingua franca in the Indonesian archipelago for half a millennium and it might be attributed to its ancestor, the Old Malay language. The Kedukan Bukit Inscription is the oldest surviving specimen of Old Malay, trade contacts carried on by various ethnic peoples at the time were the main vehicle for spreading the Old Malay language, which was the main communications medium among the traders. Ultimately, the Old Malay language became a lingua franca and was spoken widely by most people in the archipelago, Indonesian is essentially the same language as the official Malaysian, Singaporean and Brunei standards of Malay. However, it does differ from Malaysian in several respects, with differences in pronunciation and these differences are due mainly to the Dutch and Javanese influences on Indonesian. Indonesian was also influenced by the Melayu pasar, which was the lingua franca of the archipelago in colonial times, and thus indirectly by other spoken languages of the islands. Malaysian Malay claims to be closer to the classical Malay of earlier centuries, even though modern Malaysian has been influenced, in lexicon as well as in syntax. The question of whether High Malay or Low Malay was the parent of the Indonesian language is still in debate. Some linguists have argued that it was the more common Low Malay that formed the base of the Indonesian language, however, the language had never been dominant among the population of the Indonesian archipelago as it was limited to mercantile activity. The VOC adopted the Malay language as the language of their trading outpost in the east. Following the bankruptcy of the VOC the Dutch crown took control of the colony in 1799 and it was then that education in. Even then, Dutch administrators were reluctant to promote the use of Dutch compared to other colonial regimes. Dutch thus remained the language of a elite, in 1940

Borneo
–
Borneo is the third-largest island in the world and the largest island in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, the island is politically divided among three countries, Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory, in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. Additionally, the Malaysian federal territory of Labuan is situated on an island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, antipodal to an area of Amazon rainforest, Borneo is itself home to one of the oldest rainforests in the world, and to Bornean orangutans. The island is known by names, internationally it is known as Borneo, after Brunei. The name Brunei possibly was derived from the Sanskrit word váruṇa, meaning either ocean or the mythological Varuna. Indonesian natives called it Kalimantan, which was derived from the Sanskrit word Kalamanthana, prior to that the island was also known by other names. In 977 Chinese records began to use the term Po-ni to refer to Borneo or Brunei, in 1225 it was also mentioned by the Chinese official Chau Ju-Kua. The Javanese manuscript Nagarakretagama, written by Majapahit court poet Mpu Prapanca in 1365, mentioned the island as Nusa Tanjungnagara, to the west of Borneo are the Malay Peninsula and Sumatra. To the south and east are islands of Indonesia, Java and Sulawesi, to the northeast are the Philippine Islands. With an area of 743,330 square kilometres, it is the third-largest island in the world and its highest point is Mount Kinabalu in Sabah, Malaysia, with an elevation of 4,095 m. The largest river system is the Kapuas in West Kalimantan, with a length of 1,143 km, other major rivers include the Mahakam in East Kalimantan, the Barito in South Kalimantan, and Rajang in Sarawak. Clearwater Cave, for example, has one of the worlds longest underground rivers, deer Cave is home to over three million bats, with guano accumulated to over 100 metres deep. The South China Sea and Gulf of Thailand now submerge the former low-lying areas of the peninsula, the Borneo rainforest is 140 million years old, making it one of the oldest rainforests in the world. There are about 15,000 species of flowering plants with 3,000 species of trees,221 species of mammals and 420 species of resident birds in Borneo. There are about 440 freshwater fish species in Borneo and it is the centre of the evolution and distribution of many endemic species of plants and animals. The Borneo rainforest is one of the few remaining habitats for the endangered Bornean orangutan

Java
–
Java is an island of Indonesia. With a population of over 141 million or 145 million as of 2015 Census released in December 2015, the Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java and it was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s, Java dominates Indonesia politically, economically and culturally. Formed mostly as the result of eruptions, Java is the 13th largest island in the world. A chain of mountains forms an east–west spine along the island. Three main languages are spoken on the island, Javanese, Sundanese, of these, Javanese is the dominant, it is the native language of about 60 million people in Indonesia, most of whom live on Java. Furthermore, most residents are bilingual, speaking Indonesian as their first or second language, while the majority of the people of Java are Muslim, Java has a diverse mixture of religious beliefs, ethnicities, and cultures. Java is divided into four provinces, West Java, Central Java, East Java, and Banten, the origins of the name Java are not clear. One possibility is that the island was named after the plant, which was said to be common in the island during the time. There are other sources, the word jaú and its variations mean beyond or distant. And, in Sanskrit yava means barley, a plant for which the island was famous, Yawadvipa is mentioned in Indias earliest epic, the Ramayana. Sugriva, the chief of Ramas army dispatched his men to Yawadvipa and it was hence referred to in India by the Sanskrit name yāvaka dvīpa. Java is mentioned in the ancient Tamil text Manimekalai by Chithalai Chathanar that states that Java had a kingdom with a capital called Nagapuram, another source states that the Java word is derived from a Proto-Austronesian root word, Iawa that meaning home. The great island of Iabadiu or Jabadiu was mentioned in Ptolemys Geographia composed around 150 CE Roman Empire, Iabadiu is said to mean barley island, to be rich in gold, and have a silver town called Argyra at the west end. The name indicate Java, and seems to be derived from Hindu name Java-dvipa, Java lies between Sumatra to the west and Bali to the east. Borneo lies to the north and Christmas Island is to the south and it is the worlds 13th largest island. Java is surrounded by the Java Sea to the north, Sunda Strait to the west, Java is almost entirely of volcanic origin, it contains thirty-eight mountains forming an east–west spine that have at one time or another been active volcanoes

Sumatra
–
Sumatra is a large island in western Indonesia that is part of the Sunda Islands. It is the largest island that is entirely in Indonesia and the sixth-largest island in the world at 473,481 km2, Sumatra is an elongated landmass spanning a diagonal northwest-southeast axis. The Indian Ocean borders the west, northwest, and southwest sides of Sumatra with the chain of Simeulue, Nias. On the northeast side the narrow Strait of Malacca separates the island from the Malay Peninsula, on the southeast the narrow Sunda Strait separates Sumatra from Java. The northern tip of Sumatra borders the Andaman Islands, while on the eastern side are the islands of Bangka and Belitung, Karimata Strait. The Bukit Barisan mountains, which several active volcanoes, form the backbone of the island, while the northeast sides are outlying lowlands with swamps, mangrove. The equator crosses the island at its center on West Sumatra, the climate of the island is tropical, hot and humid with lush tropical rain forest once dominating the landscape. Sumatra was known in ancient times by the Sanskrit names of Swarnadwīpa and Swarnabhūmi, the first word mentioning the name of Sumatra was the name of Srivijayan Haji Sumatrabhumi, who sent an envoy to China in 1017. Arab geographers referred to the island as Lamri in the tenth through thirteenth centuries, late in the 14th century the name Sumatra became popular in reference to the kingdom of Samudra Pasai, which was a rising power until it was replaced by Sultanate of Aceh. Sultan Alauddin Shah of Aceh, on letters written in 1602 addressed to Queen Elizabeth I of England, referred to himself as king of Aceh, the word itself is from Sanskrit Samudra, meaning gathering together of waters, sea or ocean. European writers in the 19th century found that the inhabitants did not have a name for the island. The Melayu Kingdom was absorbed by Srivijaya, Srivijaya was a Buddhist monarchy centred in what is now Palembang. Dominating the region trade and conquest throughout the 7th to 9th centuries. The empire was a thalassocracy or maritime power that extended its influence from island to island, Palembang was a center for scholarly learning, and it was there the Chinese Buddhist pilgrim I Ching studied Sanskrit in 671 CE before departing for India. On his journey to China, he spent four years in Palembang translating Buddhist texts, Srivijayan influence waned in the 11th century after it was defeated by the Chola Empire of southern India. At the same time, Islam made its way to Sumatra through Arabs, by the late 13th century, the monarch of the Samudra kingdom had converted to Islam. Marco Polo visited the island in 1292, and Ibn Battuta visited twice during 1345–1346, Samudra was succeeded by the powerful Aceh Sultanate, which survived to the 20th century. With the coming of the Dutch, the many Sumatran princely states fell under their control

Sulawesi
–
Sulawesi, formerly known as Celebes, is an island in Indonesia. One of the four Greater Sunda Islands, and the worlds eleventh-largest island, within Indonesia, only Sumatra, Borneo and Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas, the northern Minahasa Peninsula, the East Peninsula, the South Peninsula, the Strait of Makassar runs along the western side of the island and separates the island from Borneo. The name Sulawesi possibly comes from the words sula and besi, the term sula also means tines, horn or spikes, derived from Sanskrit, as trishula refer to trident. Thus sulawesi means iron spikes, which suggested that the island was also a producer of iron edged weapons, the name came into common use in English following Indonesian independence. The name Celebes was originally given to the island by Portuguese explorers and it is widely considered a Portuguese rendering of the native name Sulawesi. Sulawesi is the worlds eleventh-largest island, covering an area of 174,600 km2, the central part of the island is ruggedly mountainous, such that the islands peninsulas have traditionally been remote from each other, with better connections by sea than by road. The three bays that divide Sulawesis peninsulas are, from north to south, the Tomini, the Tolo and these separate the Minahassa or Northern Peninsula, the East Peninsula, the Southeast Peninsula and the South Peninsula. The Strait of Makassar runs along the side of the island. The island is surrounded by Borneo to the west, by the Philippines to the north, by Maluku to the east, the Selayar Islands make up a peninsula stretching southwards from Southwest Sulawesi into the Flores Sea are administratively part of Sulawesi. All the above-mentioned islands, and many smaller ones, are part of Sulawesis six provinces. The island slopes up from the shores of the seas surrounding the island to a high, mostly non-volcanic. Active volcanoes are found in the northern Minahassa Peninsula, stretching north to the Sangihe Islands, the northern peninsula contains several active volcanoes such as Mount Lokon, Mount Awu, Soputan and Karangetang. Because of its several tectonic origin, faults scar the land, as a result, Sulawesi, in contrast to most of the other islands in the biogeographical region of Wallacea, is not truly oceanic, but a composite island at the centre of the Asia-Australia collision zone. Parts of the island were attached to either the Asian or Australian continental margin. In the west, the opening of the Makassar Strait separated West Sulawesi from Sundaland in the Eocene c.45 Mya. Before October 2014, the settlement of South Sulawesi by modern humans had been dated to c.30,000 BC on the basis of dates obtained from rock shelters in Maros. Initial settlement was probably around the mouth of the Sadan river, on the northwest coast of the peninsula, although the south coast has also been suggested

Karimata Strait
–
The Karimata Strait is the wide strait that connects the South China Sea to the Java Sea, dividing the islands of Sumatra and Borneo, both bordering the strait from Indonesian territory. It was known to British sailors in the 18-19th century as the Caramata Passage, the strait is about 150 kilometres wide, as measured from the east coast of the island of Belitung to the west coast of Borneo. The much narrower Gaspar Strait separates Belitung from Bangka Island to the west, Bangka lies close to the east coast of Sumatra, separated from it by the Bangka Strait. The Karimata Islands lie in the part of the Karimata strait, north-east of Belitung. On 28 December 2014 Indonesia AirAsia Flight 8501 crashed into the strait away from the Java Sea

South China Sea
–
The South China Sea is a marginal sea that is part of the Pacific Ocean, encompassing an area from the Karimata and Malacca Straits to the Strait of Taiwan of around 3,500,000 square kilometres. The areas importance largely results from one-third of the worlds shipping sailing through its waters, the sea and its mostly uninhabited islands are subject to competing claims of sovereignty by several countries. These claims are reflected in the variety of names used for the islands. South China Sea is the dominant term used in English for the sea, and this name is a result of early European interest in the sea as a route from Europe and South Asia to the trading opportunities of China. In the sixteenth century Portuguese sailors called it the China Sea, the International Hydrographic Organization refers to the sea as South China Sea. The Classic of Poetry, Zuo Zhuan, and Guoyu classics of the Spring and Autumn period also referred to the sea, Nan Hai, the South Sea, was one of the Four Seas of Chinese literature. There are three other seas, one for each of the four cardinal directions, during the Eastern Han dynasty, Chinas rulers called the Sea Zhang Hai. Fei Hai became popular during the Southern and Northern Dynasties period, usage of the current Chinese name, Nan Hai, became gradually widespread during the Qing Dynasty. In Southeast Asia it was called the Champa Sea or Sea of Cham. The majority of the sea came under Japanese naval control during World War II following the acquisition of many surrounding South East Asian territories in 1941. Japan calls the sea Minami Shina Kai South China Sea and this was written 南支那海 until 2004, when the Japanese Foreign Ministry and other departments switched the spelling 南シナ海, which has become the standard usage in Japan. In China, it is called the South Sea, 南海 Nánhǎi, in Malaysia, Indonesia and the Philippines, it was long called the South China Sea, with the part within Philippine territorial waters often called the Luzon Sea, Dagat Luzon, by the Philippines. However, following an escalation of the Spratly Islands dispute in 2011, a PAGASA spokesperson said that the sea to the east of the Philippines will continue to be called the Philippine Sea. In September 2012, Philippine President Benigno Aquino III signed Administrative Order No, states and territories with borders on the sea include, the Peoples Republic of China, the Republic of China, the Philippines, Malaysia, Brunei, Indonesia, Singapore, and Vietnam. Major rivers that flow into the South China Sea include the Pearl, Min, Jiulong, Red, Mekong, Rajang, Pahang, Pampanga, the International Hydrographic Organization defines the limits of the South China Sea as follows, On the South. From Fuki Kaku the North point of Formosa to Kiushan Tao on to the South point of Haitan Tao, the Mainland, the Southern limit of the Gulf of Thailand and the East coast of the Malay Peninsula. The sea lies above a drowned continental shelf, during recent ice ages global sea level was hundreds of metres lower, the South China Sea opened around 45 million years ago when the Dangerous Ground rifted away from southern China. Extension culminated in seafloor spreading around 30 million years ago, a process that propagated to the SW resulting in the V-shaped basin we see today, extension ceased around 17 million years ago

Ice age
–
An ice age is a period of long-term reduction in the temperature of Earths surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed glacial periods, in the terminology of glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres. In 1742 Pierre Martel, an engineer and geographer living in Geneva, two years later he published an account of his journey. He reported that the inhabitants of that valley attributed the dispersal of erratic boulders to the glaciers, later similar explanations were reported from other regions of the Alps. In 1815 the carpenter and chamois hunter Jean-Pierre Perraudin explained erratic boulders in the Val de Bagnes in the Swiss canton of Valais as being due to glaciers previously extending further. An unknown woodcutter from Meiringen in the Bernese Oberland advocated a similar idea in a discussion with the Swiss-German geologist Jean de Charpentier in 1834, comparable explanations are also known from the Val de Ferret in the Valais and the Seeland in western Switzerland and in Goethes scientific work. Such explanations could also be found in parts of the world. When the Bavarian naturalist Ernst von Bibra visited the Chilean Andes in 1849–1850, meanwhile, European scholars had begun to wonder what had caused the dispersal of erratic material. From the middle of the 18th century, some discussed ice as a means of transport, the Swedish mining expert Daniel Tilas was, in 1742, the first person to suggest drifting sea ice in order to explain the presence of erratic boulders in the Scandinavian and Baltic regions. In 1795, the Scottish philosopher and gentleman naturalist, James Hutton, two decades later, in 1818, the Swedish botanist Göran Wahlenberg published his theory of a glaciation of the Scandinavian peninsula. He regarded glaciation as a regional phenomenon, only a few years later, the Danish-Norwegian geologist Jens Esmark argued a sequence of worldwide ice ages. In a paper published in 1824, Esmark proposed changes in climate as the cause of those glaciations and he attempted to show that they originated from changes in Earths orbit. During the following years, Esmarks ideas were discussed and taken over in parts by Swedish, Scottish, at the University of Edinburgh Robert Jameson seemed to be relatively open to Esmarks ideas, as reviewed by Norwegian professor of glaciology Bjørn G. Andersen. Jamesons remarks about ancient glaciers in Scotland were most probably prompted by Esmark, in Germany, Albrecht Reinhard Bernhardi, a geologist and professor of forestry at an academy in Dreissigacker, since incorporated in the southern Thuringian city of Meiningen, adopted Esmarks theory. In a paper published in 1832, Bernhardi speculated about former polar ice caps reaching as far as the zones of the globe. When he read his paper before the Schweizerische Naturforschende Gesellschaft, most scientists remained sceptical, finally, Venetz convinced his friend Jean de Charpentier. De Charpentier transformed Venetzs idea into a theory with a limited to the Alps. In fact, both men shared the same volcanistic, or in de Charpentiers case rather plutonistic assumptions, about the Earths history, in 1834, de Charpentier presented his paper before the Schweizerische Naturforschende Gesellschaft

Peneplain
–
In geomorphology and geology a peneplain is a low-relief non-constructional plain. Peneplains are sometimes associated with the cycle of erosion theory of William Morris Davis, the existence of some peneplains, and peneplanation as a geomorphological process, is not without controversy, due to a lack of contemporary examples and uncertainty in identifying relic examples. By some definitions peneplains grade down to a base level represented by sea level, a common misconception about peneplains is that they ought to be featureless.

Inselberg
–
An inselberg or monadnock is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In southern and south-central Africa, a formation of granite is known as a koppie. If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, plains containing various inselbergs, inselberg plains, occur in various parts of the world including the interior of Angola, Namibia, Tanzania, Northern Finland and Swedish Lapland. An example of an inselberg is Uluru in Australia, the word inselberg is German for island mountain, the name was coined by geologist Wilhelm Bornhardt in 1900 to describe the abundance of such features found in southern Africa. At that time, the term applied only to landscape features. However, the term inselberg has since used to describe a broader geography and range of rock features. As recently as 1972, the term has been defined as steep-sided isolated hills rising abruptly above gently sloping ground. Thus, the terms monadnock and inselberg may not perfectly match, Monadnock is an originally Native American term for an isolated hill or a lone mountain that stands above the surrounding area, typically by surviving erosion. Geologists took the name from Mount Monadnock in southwestern New Hampshire and it is thought to derive from the Abenaki language, from either menonadenak or menadena. In this context, monadnock is used to describe a mountain that rises from an area of relatively flat and/or lower terrain. For instance, Mount Monadnock rises 2,000 feet above its terrain and stands, at 3,165 feet. Volcanic or other processes may give rise to a body of rock resistant to erosion, inside a body of rock such as limestone. When the less resistant rock is eroded away to form a plain, the strength of the uneroded rock is often attributed to the tightness of its jointing. The presence of a monadnock or inselberg typically indicates the existence of a plateau or highland. This is especially the case for inselbergs composed of sedimentary rock, however once exposed, the inselbergs are destroyed by marginal collapse of joint blocks and exfoliation sheets. This process leaves behind tors perched at their summits and, over time, inselbergs can be reshaped by ice sheets much the same way as roche moutonnées. In northern Sweden this kind of inselbergs have been referred as flyggbergs, the kopjes of Eastern Africa tend to be a refuge for life in the Serengeti of Tanzania and Kenya.

Anyer
–
Anyer, also known as Anjer or Angier, is a town in Banten, formerly West Java, Indonesia,82 miles west of Jakarta and 15 kilometers south of Merak. The town was a port in the 19th century, but was completely destroyed by the 1883 eruption of Krakatoa. The present settlement still houses the Cikoneng Lighthouse built by Dutch government two years later as a memorial for the townspeople killed by the eruption. It was also the point of the Great Post Road, built by the Dutch in the nineteenth century. Off the coast of Anyer is the island Pulau Sangiang, an island with vast areas of untouched jungle. The area is known for coral formations swarming with tropical fish. Anyer Beach is a tourist attraction with hot swimming water, a hotel and rental of resting sheds, boats, four-wheeled motorcycles, water scooter and a banana boat.

International Hydrographic Organization
–
The International Hydrographic Organization is the inter-governmental organisation representing hydrography. A principal aim of the IHO is to ensure that the seas, oceans. It does this through the setting of standards, the co-ordination of the endeavours of the worlds national hydrographic offices. The IHO enjoys observer status at the United Nations where it is the competent authority on hydrographic surveying. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards, the IHO was established in 1921 as the International Hydrographic Bureau. The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, there were substantial differences in hydrographic procedures charts, and publications. In 1889, an International Maritime Conference was held at Washington, D. C. similar proposals were made at the sessions of the International Congress of Navigation held at Saint Petersburg in 1908 and the International Maritime Conference held at Saint Petersburg in 1912. In 1919 the hydrographers of Great Britain and France cooperated in taking the steps to convene an international conference of hydrographers. London was selected as the most suitable place for this conference, and on 24 July 1919 and this is still the major purpose of the IHO. As a result of the conference, a permanent organization was formed, the IHB, now the IHO, began its activities in 1921 with 18 nations as members. The Principality of Monaco was selected as the seat of the organization as a result of the offer of Albert I, the IHO develops hydrographic and nautical charting standards. These standards are adopted and used by its 86 member countries and others in their surveys, nautical charts. Much has been done in the field of standardisation since the Bureau was founded, the IHO has encouraged the formation of Regional Hydrographic Commissions. Each RHC coordinates the national surveying and charting activities of countries within each region, the 15 RHCs plus the IHO Hydrographic Commission on Antarctica effectively cover the world. The IHO, in partnership with the Intergovernmental Oceanographic Commission, directs the General Bathymetric Chart of the Oceans programme, in 2010 the IHO introduced a new, contemporary hydrographic geospatial standard for modelling marine data and information, known as S-100. S-100 and any dependent product specifications are underpinned by an on-line registry accessible via the IHO website, S-100 is aligned with the ISO19100 series of geographic standards, thereby making it fully compatible with contemporary geospatial data standards. Because S-100 is based on ISO19100, it can be used by other providers for their maritime-related data

Bangka is an island lying east of Sumatra, administratively part of Sumatra, Indonesia, with a population of about 1 million. It is the part of Bangka-Belitung Province. The provincial capital, Pangkal Pinang, lies on the island, the island is administratively divided into 4 regencies and a chartered city. Bangka is an island together with Belitung Island. The size is about 12,000 km², most of the geographical faces of the island consists of lower plains, swamps, small hills, beautiful beaches, white pepper fields and tin mines. The largest town is Pangkal Pinang which also serves as the capital of Bangka-Belitung Province, sungai Liat is the second largest city in Bangka island. Mentok is the port in the west. The other important town are Toboali in the region, Koba an important tin mining town, also located on the southern part of the island. There are 4 sea ports in Bangka, Mentok on the far west, Belinyu on the far north, Sadai on the far south and it is intended, that a nuclear power station be built there. The population was 626,955 in 1990, and 960,692 in the 2010 census,1710, Bangka has been one of the worlds principal tin-producing centers. Tin production is an Indonesian government monopoly, and there is a tin smelter at Muntok, white pepper is also produced on the island. The majority of the inhabitants are Malays and Chinese, mostly Hakkas, the population is split between those work on the tin mines, palm oil plantations, rubber plantations, fisherman and those who work on pepper farms. The sultan of Palembang ceded Bangka to Britain in 1812, in 1930 Bangka had a population of 205,363. Japan occupied the island from February 1942 to August 1945 during World War II, the Japanese military perpetrated the Bangka Island massacre against Australian nurses and British and Australian servicemen and civilians. Bangka became part of independent Indonesia in 1949, the island, together with neighboring Belitung, was formerly part of South Sumatra province, but in 2000 the two islands became the new province of Bangka-Belitung. Bangka is also home to a number of communist Indonesians who have been under house arrest since the 1960s anti-Communist purge and are not permitted to leave the island, Bangka is reputedly the setting for Joseph Conrads book Lord Jim

It covers 4,800.6 km2, and had a population of 271,868 in 2014, administratively, it forms part of the province of Bangka-Belitung Islands. The island is known for its pepper and for its tin and it was in the possession of the United Kingdom from 1812 until Britain ceded control of the island to the Netherlands in the Anglo-Dutch Treaty of 1824. Its main town is Tanjung Pandan, the population was 262,357 at the 2010 Census, the latest official estimate is 271,868. There is also a population of Madurese who were settled there in the Suharto era transmigration. As a result, Christian churches were unable to gain considerable numbers of followers, today, Belitung is a religiously diverse island. Sunni Islam is the most widely practised religion, with minorities of Buddhists, Christians. It is an island of about 1,840 square miles. The highest one is Mount Tajam with a height of less than 500 metres, Belitung is bordered by the Gaspar Strait, the South China Sea and the Java Sea. Its turquoise blue sea is calm and shallow, making for great sailing, snorkeling and swimming. Belitung is popular for its abstract granite boulders and brilliant white sand beaches in Tanjung Tinggi, Tanjung Kelayang, Tanjung Binga, Belitung is a source of tin, clay, iron ore and silica sands. The Dutch mining company NV Billiton Maatschappij derives its name from the islands name, Billiton merged with BHP in 2001 to form the largest diversified resources company, BHP Billiton. The island is also a producer of products, pepper, coconut. People work as farmers, fishermen and miners, the island is easily accessible with eight daily 1-hour flights from Jakarta and 2 daily flights, with duration of 30 minutes and 50 minutes each, from Pangkal Pinang. The white sand beaches and offshore islands are helping tourism to become a part of the economy. The main tourist destinations are beaches and offshore islands/islets, the beaches are Tanjung Tinggi Beach and Tanjung Kelayang Beach, both of which have clear blue water, sand, and rocky beaches. On East Belitung, specifically Kelapa Kampit city, you would find a new tourist attraction, a magnificent Kong Hu Chu temple called Fu De Ci temple is located in Muten street. This building shortly became a piece of its city

Bali Sea
–
The Bali Sea is the body of water north of the island of Bali and south of Kangean Island in Indonesia. The sea forms the south-west part of the Flores Sea, the Bali Sea is sometimes grouped with Flores Sea for oceanographic purposes, however in some nautical charts, Bali Sea is written as a distinct sea for navigation. The sea has an area of 45,000 km2 and a depth of 1,590 m. The International Hydrographic Organization defines the Bali Sea as being one of the waters of the East Indian Archipelago, the IHO defines its limits as follows, On the North. A line from the Western Paternoster Island to the East point of Sepandjang, a line from the West point of Gedeh Bay, Kangean Island, to Tg Sedano, the Northeast extreme of Java and down the East coast to Tg Bantenan, the Southeast extreme of the island. The West and North coasts of Soembawa as far East as Tanjong Sarokaja, the circulation and mass water properties in Bali Sea are a continuation from Flores Sea to the Java Sea in the north. In oceanographic, Bali Sea is concerned with the Indonesian Throughflow coming from Pacific Ocean to the Indian Ocean, in a recorded tsunami history, Bali Sea observed several tsunamis. Two more tsunamis were recorded in 1857 and 1917 with maximum height of 3 meters and 2 meters respectively

They are located in the Java Sea approximately 120 km north of Bali and 120 km east of Madura Island, the islands are administratively a part of Sumenep Regency within East Java province. The largest island, at about 490 km², is Kangean Island, other islands include Paliat, Sepanjang, and several smaller islands. The towns of Kalikatak and Arjasa, both on Kangean Island, are the areas largest population centres, the islands have strong historic and ethnic ties with Madura, the people of Kangean are almost 100% Moslem, most residents are ethnically Madurese. The highest elevation point on the islands is in the northeast at 1,192 feet, the weather tends to rain regularly. Saltwater crocodiles are reported to be present within the islands coastal mangroves and they are administered as three districts of Sumenep Regency - Arjasa, Kangayan, and Sapeken. Together, their population was 108,264 in the 2000 census, the natural gas fields were first discovered and developed by the United States corporation ARCO, which became a subsidiary of BP in 2000. In mid-2004, BP sold its Kangean holdings to an Indonesian corporation, the islands are connected to East Java via a 430 km pipeline, most of which runs underwater. Other economic activities on the islands include teak, coconut, in 2014, the local government agreed to reactivate an old airstrip on Kangean Island. The airstrip is 1,000 meters long and 30 meters wide

Battle of the Java Sea
–
The Battle of the Java Sea was a decisive naval battle of the Pacific campaign of World War II. Allied navies suffered a defeat at the hand of the Imperial Japanese Navy, on 27 February 1942. The American-British-Dutch-Australian Command Strike Force commander— Dutch Rear-Admiral Karel Doorman—was killed, the aftermath of the battle included several smaller actions around Java, including the smaller but also significant Battle of Sunda Strait. These defeats led to Japanese occupation of the entire Netherlands East Indies, at the time, the battle was the largest surface ship engagement since the Battle of Jutland in 1916. The Japanese invasion of the Dutch East Indies progressed at a pace as they advanced from their Palau Islands colony and captured bases in Sarawak. To oppose these forces was a small force, consisting of Dutch, American. On 23 January 1942, a force of four American destroyers attacked a Japanese invasion convoy in Makassar Strait as it approached Balikpapan in Borneo, on 13 February, the Allies fought unsuccessfully—in the Battle of Palembang—to prevent the Japanese from capturing the major oil port in eastern Sumatra. On the night of 19/20 February, an Allied force attacked the Eastern Invasion Force off Bali in the Battle of Badung Strait. Also on 19 February, the Japanese made two air raids on Darwin, on the Australia mainland, one from carrier based planes, the destruction of Darwin rendered it useless as a supply and naval base to support operations in the East Indies. Shortly before the battle commenced, the odds were not good for the Allied forces and they lacked cohesion and were demoralized by constant air attacks and a general sentiment that the Japanese were unbeatable. In addition, the coordination between Allied navies and air forces was poor, the Eastern Strike Force, as it was known, consisted of two heavy cruisers, three light cruisers, and nine destroyers. The Japanese heavy cruisers were more powerful, armed with ten 8-inch guns each. By comparison, Exeter was armed only with six 8-inch guns, the Allies had local air superiority during the daylight hours, because Japanese air power could not reach the fleet in the bad weather. The weather also hindered communications, making cooperation between the many Allied parties involved—in reconnaissance, air cover and fleet headquarters—even worse than it already was, the Japanese also jammed the radio frequencies. Exeter was the ship in the battle equipped with radar. The fleets sighted each other at about 16,00 on 27 February and closed to firing range, both sides exhibited poor gunnery and torpedo skills during this phase of the battle. Despite her recent refit, Exeters shells did not come close to the Japanese ships, the only notable result of the initial gunnery exchange was Exeter being critically damaged by a hit in the boiler room from an 8-inch shell. The ship then limped away to Surabaya, escorted by Witte de With, the Japanese launched two huge torpedo salvoes, consisting of 92 torpedoes in all, but scored only one hit, on Kortenaer

Naval warfare
–
Naval warfare is combat in and on the sea, the ocean, or any other major body of water such as a large lake or wide river. Mankind has fought battles on the sea for more than 3,000 years, even in the interior of large landmasses, transportation before the advent of extensive railroads was largely dependent upon rivers, canals, and other navigable waterways. Prior to 1750, materials largely moved by barge or sea vessels. Thus armies, with their exorbitant needs for food, ammunition, the oceanic influences throughout pre-recorded history, and classical works such as The Odyssey underscore the past influences. The Persian Empire – united and strong – could not prevail against the might of the Athenian fleet combined with that of city states in several attempts to conquer the Greek city states. Phoenicias and Egypts power, Carthages and even Romes largely depended upon control of the seas, so too did the Venetian Republic dominate Italys city states, thwart the Ottoman Empire, and dominate commerce on the Silk Road and the Mediterranean in general for centuries. For three centuries, the Northmen raided and pillaged and went where they willed, far into central Russia and the Ukraine, many sea battles through history also provide a reliable source of shipwrecks for underwater archaeology. A major example is the exploration of the wrecks of various warships in the Pacific Ocean, the first dateable recorded sea battle occurred about 1210 BC, Suppiluliuma II, king of the Hittites, defeated a fleet from Cyprus, and burned their ships at sea. In the Battle of the Delta, the Ancient Egyptians defeated the Sea Peoples in a sea battle circa 1175 BC, no written mention of strategy or tactics seems to have survived. Josephus Flavius reports a battle between Tyre and the king of Assyria who was aided by the other cities in Phoenicia. The battle took place off the shores of Tyre, although the Tyrian fleet was much smaller in size, the Tyrians defeated their enemies. The Greeks of Homer just used their ships as transport for land armies and it seems unlikely that all this was the product of a single mind or even of a generation, most likely the period of evolution and experimentation was simply not recorded by history. After some initial battles while subjugating the Greeks of the Ionian coast, the Persians determined to invade Greece proper. The first Persian campaign, in 492 BC, was aborted because the fleet was lost in a storm, attacks by the Greek armies repulsed these. The third Persian campaign in 480 BC, under Xerxes I of Persia, but the defeat on land at Thermopylae forced a Greek withdrawal, and Athens evacuated its population to nearby Salamis Island. The ensuing Battle of Salamis was one of the engagements of history. Themistocles trapped the Persians in a too narrow for them to bring their greater numbers to bear. Aeschylus wrote a play about the defeat, The Persians, which was performed in a Greek theatre competition a few years after the battle and it is the oldest known surviving play

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Indonesia AirAsia Flight 8501
–
Indonesia AirAsia Flight 8501 was a scheduled international passenger flight, operated by AirAsia Group affiliate Indonesia AirAsia, from Surabaya, Indonesia, to Singapore. Two days after the crash, debris from the aircraft and human remains were floating in the Java Sea. Searchers located wreckage on the sea floor beginning on 3 January 2015, the search for bodies ended in March 2015 after recovery of 106 of the 162 bodies. The aircraft had stalled during a steep climb and had been unable to recover. The pilots response, and apparent miscommunication between them, was a significant link in the chain of events led to the loss of the aircraft. The air crash became the second-deadliest in Indonesian territory, behind Garuda Indonesia Flight 152 in 1997 and it was also the second deadliest plane crash involving an Airbus A320 and the third deadliest involving an Airbus A320 family. It was the third deadliest plane crash in 2014, Flight 8501 was a scheduled flight from Surabaya, Java, Indonesia to Singapore on Sunday,28 December 2014. It was scheduled to depart Juanda International Airport at 05,20 Western Indonesian Time, Flight 8501 took off at 05,35. Indonesia AirAsia did not have permission from the Indonesian Ministry of Transportation to operate the route on Sundays. At 06,12, Flight 8501 was flying at flight level 320—approximately 32,000 ft —when the cockpit requested and received permission to deviate left from its flight path to avoid these storms. The pilot then requested to climb to flight level 380, which was deferred by ATC because of aircraft in the vicinity. The aircraft also began a turn to the left, forming at least one complete circle before disappearing from radar at 06,18,44 and its last recorded position was over the Java Sea, Karimata Strait between the islands of Belitung and Kalimantan. The cockpit voice recorder captured multiple warnings, including a warning, sounding in the cockpit during the final minutes of the flight. No distress signal was sent from the aircraft, Search and rescue operations were activated by the Indonesia National Search and Rescue Agency from the Pangkal Pinang office. The aircraft was an Airbus A320-216, with serial number 3648 and it first flew on 25 September 2008, and was delivered to AirAsia on 15 October 2008. The aircraft had accumulated approximately 23,000 flight hours over 13,600 flights and it had undergone its most recent scheduled maintenance on 16 November 2014. The aircraft was powered by two CFM International CFM56-5B6 engines and was configured to carry 180 passengers, AirAsia released details of the 155 passengers which included 137 adults,17 children, and one infant. The crew consisted of two pilots and four flight attendants, a company engineer was also on board and was not counted as one of the passengers

Singapore
–
Singapore, officially the Republic of Singapore, sometimes referred to as the Lion City or the Little Red Dot, is a sovereign city-state in Southeast Asia. It lies one degree north of the equator, at the tip of peninsular Malaysia. Singapores territory consists of one island along with 62 other islets. Since independence, extensive land reclamation has increased its size by 23%. During the Second World War, Singapore was occupied by Japan, after early years of turbulence, and despite lacking natural resources and a hinterland, the nation developed rapidly as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global commerce, finance and transport hub, the country has also been identified as a tax haven. Singapore ranks 5th internationally and first in Asia on the UN Human Development Index and it is ranked highly in education, healthcare, life expectancy, quality of life, personal safety, and housing, but does not fare well on the Democracy index. Although income inequality is high, 90% of homes are owner-occupied, 38% of Singapores 5.6 million residents are permanent residents and other foreign nationals. There are four languages on the island, Malay, Mandarin, Tamil. English is its language, most Singaporeans are bilingual. Singapore is a multiparty parliamentary republic, with a Westminster system of unicameral parliamentary government. The Peoples Action Party has won every election since self-government in 1959, however, it is unlikely that lions ever lived on the island, Sang Nila Utama, the Srivijayan prince said to have founded and named the island Singapura, perhaps saw a Malayan tiger. There are however other suggestions for the origin of the name, the central island has also been called Pulau Ujong as far back as the third century CE, literally island at the end in Malay. In 1299, according to the Malay Annals, the Kingdom of Singapura was founded on the island by Sang Nila Utama and these Indianized Kingdoms, a term coined by George Cœdès were characterized by surprising resilience, political integrity and administrative stability. In 1613, Portuguese raiders burned down the settlement, which by then was part of the Johor Sultanate. The wider maritime region and much trade was under Dutch control for the following period, in 1824 the entire island, as well as the Temenggong, became a British possession after a further treaty with the Sultan. In 1826, Singapore became part of the Straits Settlements, under the jurisdiction of British India, prior to Raffles arrival, there were only about a thousand people living on the island, mostly indigenous Malays along with a handful of Chinese. By 1860 the population had swelled to over 80,000, many of these early immigrants came to work on the pepper and gambier plantations

Surabaya
–
Surabaya, is the capital of Jawa Timur, located on northeastern Java island and along the edge of the Madura Strait and the second-largest-city in Indonesia. At the 2010 census, the city had a population over 2, Surabaya was once the largest city in Dutch East Indies and virtually the center of trading in the nation, exceeding those of Batavia, competing with the likes of Shanghai and Hong Kong. It was said that the two powerful animals agreed for a truce and set boundaries, that the domain would be in the sea while the crocodiles domain would be on the land. However one day the shark swam into the estuary to hunt, this angered the crocodile. The Shark argued that the river was a water-realm which meant that it was shark territory, while the crocodile argued that the river flowed deep inland, a ferocious fight resumed as the two animals bit each other. Finally the shark was badly bitten and fled to the sea. The two animals are now used as the symbol, with the two facing and circling each other, as depicted in a statue appropriately located near the entrance to the city zoo. Alternate derivations proliferate, from the Javanese sura ing baya, meaning bravely facing danger, some people consider Jayabayas prophecy as being about the great war between native Surabayan people and foreign invaders at the start of the war of independence in 1945. Another story tells of two heroes who fought each other in order to be the king of the city, the two heroes were named Sura and Baya. These folk etymologies, though embraced enthusiastically by its people and city leaders, are unverifiable, the earliest record of Surabaya was in the 1225 book Zhu fan zhi written by Zhao Rugua, in which it was called Jung-ya-lu, the ancient name of Surabaya. At the estuary, the water is fresh. In the fifteenth and sixteenth centuries, Surabaya was a duchy and it entered a conflict with, and was later captured by, the more powerful Sultanate of Mataram in 1625 under Sultan Agung. It was one of Matarams fiercest campaigns, in which they had to conquer Surabayas allies, Sukadana and Madura, with this conquest, Mataram then controlled almost the whole of Java, with the exception of the Sultanate of Banten and the Dutch settlement of Batavia. The expanding Dutch East India Company took the city over from a weakened Mataram in November 1743, Surabaya became a major trading center under the Dutch colonial government, and hosted the largest naval base in the colony. Surabaya was also the largest city in the serving as the center of Javas plantation economy. However, by 1920 a census recorded that Batavia has overtaken Surabayas population size, in 1917, a revolt occurred among the soldiers and sailors of Surabaya, led by the Indies Social Democratic Association. The revolt was crushed and the insurgents given harsh sentences. Japan occupied the city in 1942, as part of the occupation of Indonesia, after Japanese surrender at the end of World War II Surabaya was seized by Indonesian nationalists

Kalimantan
–
Kalimantan is the Indonesian portion of the island of Borneo. It comprises 73% of the islands area, the non-Indonesian parts of Borneo are Brunei and East Malaysia. In Indonesian, the term Kalimantan refers to the island of Borneo. It consists of the two words kal and manthan, the word Kalamanthana is spelled Kalmantan, and then the indigenous people fixed it into Klemantan. The Indonesian territory makes up 73% of the island by area, the non-Indonesian parts of Borneo are of Brunei and East Malaysia, the latter comprising the states of Sabah, Sarawak and the federal territory of Labuan. The region within Indonesia is also known as Indonesian Borneo, kalimantans total area is 544,150 square kilometres. Kalimantan is divided into five provinces, 1)North Kalimantan split off East Kalimantan with resulting population, languages of Kalimantan Kalimantan travel guide from Wikivoyage

Karimunjava
–
Crimon Java Islands or Karimunjava Islands is an archipelago of 27 islands in the Java Sea, Indonesia, approximately 80 kilometres northwest of Jepara. The islands name means a stones throw from Java in Javanese and they have a total land area of 78 km2. The main island is known as Karimun, while the second-largest island is Kemujan, in 2011, the population of the island group was about 9,000 who lived on five of the islands. The population is largely Javanese, with pockets of Bugis and Madurese inhabitants, Javanese culture is dominant in the islands which are the only islands off Java where Javanese is the lingua franca. Twenty-two of the islands have been declared 2001 as a marine reserve, five more islands are either privately owned or are under the control of the Indonesian Navy. The Karimunjava islands are a subdistrict made up of five villages which is a part of the Jepara district of Central Java province, the island of Bawean lies east of this group, as part of Gresik district, East Java province. Apart from use as a base, the islands are believed to have been uninhabited until a penal settlement was established during the British occupation of Java in the early seventeenth century. Archeological finds of Chinese ceramics on the seabed near the islands date from around the 13th century suggest that the islands were once part of a trade route to Java. The settlement was abandoned by the Dutch during the Java War of 1825–1830, cotton plantations set up during the convict period became a major source of income, as did goldsmithing. The islands were declared a park in 1988. The archipelago consists predominantly of pre-Tertiary continental islands primarily of quartzites and shales covered by basaltic lava, geologically, the islands are part of Sundaland. The islands have extensive fringing and patchy coral reefs, the best time to visit the islands is during the dry season, generally from April to October. The main source of income for the population is fishing, followed by services. Travel to the islands from Java is sometimes limited during the season around the January–March period during bad weather which can bring large waves to the area. There are a number of snorkeling spots, there is pressure on local environmental resources because of the rapidly expanding tourist industry

Thousand Islands (Indonesia)
–
The Thousand Islands are a chain of islands to the north of Jakartas coast. It forms the only regency of Jakarta, the capital of Indonesia and it consists of a string of 110 islands stretching 45 km north into the Java Sea at West Jakarta Bay and in fact north of Banten Province. A decree states that 36 islands may be used for recreation, of these, only 13 islands are fully developed,11 islands are homes to resorts and two islands are historic parks. 23 are privately owned and are not open to the public, the rest of the islands are either uninhabited or support a fishing village. The modern history of the Thousand Islands begins with its role in the defenses of the city of Batavia for the VOC, before the arrival of the Dutch, these islands already had a Malay name. With the arrival of the Dutch, the received a second Dutch name. The Malay names are not forgotten, as both Malay and Dutch names of the islands are written side by side in some 18th-century Batavia map. Since the establishment of Batavia in 1610, Pulau Kapal, later named by the Dutch as Onrust island, has been a naval base, the island Prince Jayakarta assigned to the VOC was Onrust Island, a 12-hectare island 14 km from Jakarta. The VOC constructed a rectangular fort with two bastions in 1656, the bastions protruded from the fort and were used as look-out posts. The Dutch enlarged the fort in 1671 and gave it a pentagonal shape with a bastion in each corner. The whole structure was made of red bricks and coral, in 1674 additional storage buildings were built. Daedalus, HMS Sybille, HMS Centurion and HMS Braave entered the area and they seized five Dutch armed vessels and destroyed 22 other vessels. Onrust island was under siege by the British and eventually destroyed, after the British departed, the Dutch rebuilt the buildings and facilities, completing the work in 1806. However, a second British attack, led by Admiral Edward Pellew, when the British occupied Batavia in 1810, they repaired the buildings in Onrust island until prior to their leaving Indonesia in 1816. Onrust island again received attention in 1827 during the period of Governor General G. A. Baron Van Der Capellen, in 1856 a floating shipyard was built. However, the construction of Tanjung Priok harbour in 1883 resulted in a decline in the role, in 1911-1933, Onrust island became a quarantine station for pilgrims returning from the Hajj. A barrack was built in 1911 that contained 35 units for about 100 pilgrims, from 1933 until 1940, the Dutch used Onrust to hold the mutineers involved in the Incident of the Seven Ships. In 1940, the Dutch used it to hold Germans, such as Steinfurt, after the Japanese invaded Indonesia in 1942, the role of Onrust island declined again and it became a prison for serious criminals

Jakarta
–
Jakarta /dʒəˈkɑːrtə/, officially the Special Capital Region of Jakarta, is the capital and most populous city of the Republic of Indonesia. Located on the northwest coast of the worlds most populous island of Java, Jakarta is the economic, cultural and political centre. The official metropolitan area, known as Jabodetabek, is the second largest in the world, established in the fourth century, the city became an important trading port for the Kingdom of Sunda. It was the de facto capital of the Dutch East Indies, today, the city has continued as the capital of Indonesia since the countrys independence was declared in 1945. Jakarta is listed as a city in the 2012 Globalization and World Cities Study Group. Based on the global metro monitor by the Brookings Institution, in 2014, Jakarta has grown more rapidly than Kuala Lumpur, Beijing, and Bangkok. Jakarta has been home to multiple settlements along with their names, Sunda Kelapa, Jayakarta, Batavia, Djakarta. Its current name derives from the word Jayakarta, the origins of this word can be traced to the Old Javanese and ultimately to the Sanskrit language. Jayakarta translates as victorious deed, complete act, or complete victory, Jakarta is nicknamed the Big Durian, the thorny strongly-odored fruit native to the region, as the city is seen as the Indonesian equivalent of the US city of New York. In the colonial era, the city was known as Koningin van het Oosten, initially in the 17th century for the urban beauty of downtown Batavias canals, mansions. After expanding to the south in the 19th century, this came to be more associated with the suburbs, with their wide lanes, many green spaces. The area in and around modern Jakarta was part of the fourth century Sundanese kingdom of Tarumanagara, following the decline of Tarumanagara, its territories, including the Jakarta area, became part of the Hindu Kingdom of Sunda. From 7th to early 13th century port of Sunda was within the sphere of influence of the Srivijaya maritime empire. According to the Chinese source, Chu-fan-chi, written circa 1225, Chou Ju-kua reported in the early 13th century Srivijaya still ruled Sumatra, the source reports the port of Sunda as strategic and thriving, pepper from Sunda being among the best in quality. The people worked in agriculture and their houses were built on wooden piles, the harbour area became known as Sunda Kelapa and by the fourteenth century, it was a major trading port for Sunda kingdom. The first European fleet, four Portuguese ships from Malacca, arrived in 1513 when the Portuguese were looking for a route for spices, in 1527, Fatahillah, a Javanese general from Demak attacked and conquered Sunda Kelapa, driving out the Portuguese. Sunda Kelapa was renamed Jayakarta, and became a fiefdom of the Sultanate of Banten which became a major Southeast Asia trading centre, through the relationship with Prince Jayawikarta from the Sultanate of Banten, Dutch ships arrived in Jayakarta in 1596. In 1602, the English East India Companys first voyage, commanded by Sir James Lancaster, arrived in Aceh and this site became the centre of English trade in Indonesia until 1682

Regency (Indonesia)
–
This is the list of regencies and cities of Indonesia. Both regencies and cities are second-level administrative subdivision in Indonesia, immediately below the provinces, in Indonesia, both regency and city are at the same administration level, each having their own local government and legislative body. The difference between a regency and a city lies in demography, size and economy, generally, a regency comprises a rural, larger area than a city. A city usually has non-agricultural economic activities, a regency is headed by a regent, known locally as bupati, while a city is headed by a mayor. All regents, mayors and members of legislatures are elected via elections to serve for a five year term which can be renewed once. Each regency or city is divided further into districts more commonly known as kecamatan, an administrative city is a city without its own local legislatures. The mayor of a city is directly appointed by the Governor. This type of city in Indonesia is only found in Jakarta which consisted of 5 administrative cities and 1 administrative regency, following the implementation of decentralization beginning on 1 January 2001, regencies and municipalities became the key administrative units responsible for providing most governmental services. The list below groups regencies and cities in Indonesia by provinces, each regency has an administrative centre, the regency seat. The Indonesian title of bupati is originally a loanword from Sanskrit originating in India, related titles which were also used in precolonial Indonesia are adipati and senapati. A regency is a subdivision of a province in Indonesia. The Indonesian term kabupaten is also translated as municipality. Regencies and cities are divided into Districts, the English name regency comes from the Dutch colonial period, when regencies were ruled by bupati and were known as regentschap. Bupati had been regional lords under the pre-colonial monarchies of Java, when the Dutch abolished or curtailed those monarchies, the bupati were left as the most senior indigenous authority. They were not strictly speaking native rulers because the Dutch claimed full sovereignty over their territory, regencies in Java territorial units were grouped together into Residencies headed by exclusively European Residents. After the independence of Indonesia in 1945, the terms bupati, since the start of Reformasi in 1998 a remarkable secession of district governments has arisen in Indonesia. This process has become known as pemekaran, following the surge of support for decentralisation across Indonesia which occurred following the end of the Soeharto era in 1998, key new decentralisation laws were passed in 1999. Subsequently, there was a jump in the number of regencies from around 300 at the end of 1998 to over 490 in 2008 ten years later, the agreement will be forwarded on for government approval

Tourist
–
Tourism is travel for pleasure or business, also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the travellers country, Tourism can be domestic or international, and international tourism has both incoming and outgoing implications on a countrys balance of payments. Today, tourism is a source of income for many countries. International tourism receipts grew to US$1.03 trillion in 2011, the ITB Berlin is the worlds leading tourism trade fair. The word tourist was used by 1772 and tourism by 1811. It is formed from the tour, which is derived from Old English turian, from Old French torner, from Latin tornare, to turn on a lathe. Tourism is an important, even vital, source of income for many regions and it also creates opportunities for employment in the service sector of the economy associated with tourism. This is in addition to goods bought by tourists, including souvenirs, in 1936, the League of Nations defined a foreign tourist as someone traveling abroad for at least twenty-four hours. Its successor, the United Nations, amended this definition in 1945 and it includes movements for all purposes. In 1981, the International Association of Scientific Experts in Tourism defined tourism in terms of particular activities chosen and undertaken outside the home, in this context, travel has a similar definition to tourism, but implies a more purposeful journey. The terms tourism and tourist are sometimes used pejoratively, to imply a shallow interest in the cultures or locations visited, by contrast, traveler is often used as a sign of distinction. The sociology of tourism has studied the values underpinning these distinctions. International tourist arrivals reached 1.035 billion in 2012, up from over 996 million in 2011, the World Tourism Organization reports the following ten destinations as the most visited in terms of the number of international travellers in 2016. International tourism receipts grew to US$1.2 trillion in 2014, based upon air traffic, the MasterCard Global Destination Cities Index reports the following cities as the top ten most popular destinations of international tourism worldwide. MasterCard reports the following cities as the top ten biggest earners on international tourism worldwide in 2015, as early as Shulgi, however, kings praised themselves for protecting roads and building waystations for travelers. During the Roman Republic, spas and coastal resorts such as Baiae were popular among the rich, pausanias wrote his Description of Greece in the 2nd century AD. In ancient China, nobles sometimes made a point of visiting Mount Tai and, on occasion, the Islamic hajj is still central to its faith and Chaucers Canterbury Tales and Wu Chengens Journey to the West remain classics of English and Chinese literature. The 10th- to 13th-century Song dynasty also saw secular travel writers such as Su Shi, under the Ming, Xu Xiake continued the practice

Scuba diving
–
Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus which is completely independent of surface supply, to breathe underwater. They may include additional cylinders for decompression gas or emergency breathing gas, closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases. The volume of gas used is reduced compared to that of open circuit, therefore, scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. A scuba diver primarily moves underwater by using fins attached to the feet, scuba divers are trained in the procedures and skills appropriate to their level of certification by instructors affiliated to the diver certification organisations which issue these certifications. A minimum level of fitness and health is required by most training organisations, the closed-circuit rebreathers were first developed for escape and rescue purposes, and were modified for military use, due to their stealth advantages, as they produce very few bubbles. The first commercially successful closed-circuit scuba was designed and built by English diving engineer, Henry Fleuss in 1878, while working for Siebe Gorman in London. Sir Robert Davis, head of Siebe Gorman, improved the oxygen rebreather in 1910 with his invention of the Davis Submerged Escape Apparatus, rebreathers have been increasingly used by civilians for recreation, especially since the end of the Cold War. This reduced the risk of attack by Communist Bloc forces. After that, the armed forces had less reason to requisition civilian rebreather patents. The single hose two stage scuba regulators trace their origins to Australia, where Ted Eldred developed the first example of type of regulator. This was developed because patents protected the Aqualungs twin hose design, the single hose regulator separates the demand valve from the cylinder, giving the diver air at the ambient pressure at the mouth, rather than ambient pressure at the cylinder valve. The term SCUBA originally referred to United States combat frogmens oxygen rebreathers, SCUBA was originally an acronym, but is now generally used as a common noun or adjective, scuba. It has become acceptable to refer to equipment or scuba apparatus—examples of the linguistic RAS syndrome. Scuba diving may be performed for a number of reasons, both personal and professional, recreational diving is done purely for enjoyment and has a number of technical disciplines to increase interest underwater, such as cave diving, wreck diving, ice diving and deep diving. Divers may be employed professionally to perform tasks underwater, some of these tasks are suitable for scuba. There are divers who work, full or part-time, in the diving community as instructors, assistant instructors, divemasters. Other specialist areas of diving include military diving, with a long history of military frogmen in various roles. Their roles include direct combat, infiltration behind enemy lines, placing mines or using a manned torpedo, in some cases diver rescue teams may also be part of a fire department, paramedical service or lifeguard unit, and may be classed as public service diving

Coral
–
Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans, a coral group is a colony of myriad genetically identical polyps. Each polyp is an animal typically only a few millimeters in diameter. A set of tentacles surround a central mouth opening, an exoskeleton is excreted near the base. Over many generations, the colony creates a large skeleton that is characteristic of the species. Individual heads grow by reproduction of polyps. Corals also breed sexually by spawning, polyps of the same species release gametes simultaneously over a period of one to several nights around a full moon and these are commonly known as zooxanthellae and the corals that contain them are zooxanthellate corals. Such corals require sunlight and grow in clear, shallow water, other corals do not rely on zooxanthellae and can live in much deeper water, with the cold-water genus Lophelia surviving as deep as 3,000 metres. Some have been found on the Darwin Mounds, north-west of Cape Wrath, Corals have also been found as far north as off the coast of Washington State and the Aleutian Islands. In his Scala Naturae, Aristotle classified corals as zoophyta, animals that had characteristics of plants and were therefore hypothetically in between animals and plants, the Persian polymath Al-Biruni classified sponges and corals as animals, arguing that they respond to touch. The phylogeny of Anthozoans is not clearly understood and a number of different models have been proposed, within the Hexacorallia, the sea anemones, coral anemones and stony corals may constitute a monophyletic grouping united by their eight-fold symmetry and cnidocyte trait. The Octocorallia appears to be monophyletic, and primitive members of this group may have been stolonate, the cladogram presented here comes from a 2014 study by Stampar et al. which was based on the divergence of mitochondrial DNA within the group and on nuclear markers. Corals are classified in the class Anthozoa of the phylum Cnidaria and they are divided into three subclasses, Hexacorallia, Octocorallia, and Ceriantharia. The Hexacorallia include the stony corals, the sea anemones and the zoanthids and these groups have polyps that generally have 6-fold symmetry. The Octocorallia include blue coral, soft corals, sea pens and these groups have polyps with 8-fold symmetry, each polyp having eight tentacles and eight mesenteries. Fire corals are not true corals, being in the order Anthomedusa of the class Hydrozoa, Corals are sessile animals in the class Anthozoa and differ from most other cnidarians in not having a medusa stage in their life cycle. The body unit of the animal is a polyp, most corals are colonial, the initial polyp budding to produce another and the colony gradually developing from this small start

Sponge
–
Sponges are the basalmost clade of animals of the phylum Porifera. Sponges have unspecialized cells that can transform into other types and that often migrate between the cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems, instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges are similar to animals in that they are multicellular, heterotrophic, lack cell walls. Unlike other animals, they lack true tissues and organs, and have no body symmetry, the shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where it deposits nutrients, and leaves through a hole called the osculum. Many sponges have internal skeletons of spongin and/or spicules of calcium carbonate or silicon dioxide, all sponges are sessile aquatic animals. Although there are species, the great majority are marine species. A few species of sponge that live in food-poor environments have become carnivores that prey mainly on small crustaceans, most species use sexual reproduction, releasing sperm cells into the water to fertilize ova that in some species are released and in others are retained by the mother. The fertilized eggs form larvae which swim off in search of places to settle, sponges are known for regenerating from fragments that are broken off, although this only works if the fragments include the right types of cells. A few species reproduce by budding, the mesohyl functions as an endoskeleton in most sponges, and is the only skeleton in soft sponges that encrust hard surfaces such as rocks. More commonly, the mesohyl is stiffened by mineral spicules, by spongin fibers or both, demosponges use spongin, and in many species, silica spicules and in some species, calcium carbonate exoskeletons. Demosponges constitute about 90% of all known species, including all freshwater ones. The fragile glass sponges, with scaffolding of silica spicules, are restricted to polar regions, fossils of all of these types have been found in rocks dated from 580 million years ago. In addition Archaeocyathids, whose fossils are common in rocks from 530 to 490 million years ago, are now regarded as a type of sponge, the single-celled choanoflagellates resemble the choanocyte cells of sponges which are used to drive their water flow systems and capture most of their food. This along with studies of ribosomal molecules have been used as morphological evidence to suggest sponges are the sister group to the rest of animals. Some studies have shown that sponges do not form a group, in other words do not include all. Recent phylogenetic analyses suggest that comb jellies rather than sponges are the group to the rest of animals. By the 1950s, though, these had been overfished so heavily that the industry almost collapsed, sponges and their microscopic endosymbionts are now being researched as possible sources of medicines for treating a wide range of diseases

Google Earth
–
It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and geographic information system onto a 3D globe. It was originally available with three different licenses, but has since reduced to just two, Google Earth and Google Earth Pro, which is now free and is intended for commercial use. The third original option, Google Earth Plus, has been discontinued. The product, re-released as Google Earth in 2005, is available for use on computers running Windows 2000 and above, Mac OS X10.3.9 and above, Linux kernel,2.6 or later. Google Earth is also available as a plugin which was released on May 28,2008. It was also available for mobile viewers on the iPhone OS on October 28,2008, as a free download from the App Store. In addition to releasing an updated Keyhole based client, Google also added the imagery from the Earth database to their web-based mapping software, as of October 2011, Google Earth has been downloaded more than a billion times. Google Earth displays satellite images of varying resolution of the Earths surface, Imagery resolution ranges from 15 meters of resolution to 15 centimeters. Most areas in Google Earth are only shown in 2D aerial imagery, Google Earth uses digital elevation model data collected by NASAs Shuttle Radar Topography Mission. This means one can view almost the entire earth in three dimensions, since November 2006, the 3D views of many mountains, including Mount Everest, have been improved by the use of supplementary DEM data to fill the gaps in SRTM coverage. Google Earth allows users to search for addresses for some countries, enter coordinates, some people use the applications to add their own data, making them available through various sources, such as the Bulletin Board Systems or blogs mentioned in the link section below. Google Earth is able to show various kinds of images overlaid on the surface of the earth and is also a Web Map Service client, Google Earth supports managing three-dimensional Geospatial data through Keyhole Markup Language. In December 2006, Google Earth added a new layer called Geographic Web that includes integration with Wikipedia, in Wikipedia, entries are scraped for coordinates via the Coord templates. There is also a community-layer from the project Wikipedia-World, More coordinates are used, different types are in the display and different languages are supported than the built-in Wikipedia layer. Google announced on May 30,2007 that it is acquiring Panoramio, in March 2010, Google removed the Geographic Web layer. The Panoramio layer became part of the layers and the Wikipedia layer was placed in the More layer. In Google Earth v4.2 a flight simulator was included as a hidden feature, starting with v4.3 it is no longer hidden. The flight simulator could be accessed by holding down the keys Ctrl, Alt, initially the F-16 Fighting Falcon and the Cirrus SR-22 were the only aircraft available, and they could be used with only a few airports

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Indian Ocean
–
The Indian Ocean is the third largest of the worlds oceanic divisions, covering 70,560,000 km2. It is bounded by Asia on the north, on the west by Africa, on the east by Australia, the Indian Ocean is known as Ratnākara, the mine of gems in ancient Sanskrit literature, and as Hind Mahāsāgar, in Hindi. The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf, the oceans continental shelves are narrow, averaging 200 kilometres in width. An exception is found off Australias western coast, where the width exceeds 1,000 kilometres. The average depth of the ocean is 3,890 m and its deepest point is Diamantina Deep in Diamantina Trench, at 8,047 m deep, Sunda Trench has a depth of 7, 258–7,725 m. North of 50° south latitude, 86% of the basin is covered by pelagic sediments. The remaining 14% is layered with terrigenous sediments, glacial outwash dominates the extreme southern latitudes. The major choke points include Bab el Mandeb, Strait of Hormuz, the Lombok Strait, the Strait of Malacca, the Indian Ocean is artificially connected to the Mediterranean Sea through the Suez Canal, which is accessible via the Red Sea. All of the Indian Ocean is in the Eastern Hemisphere and the centre of the Eastern Hemisphere is in this ocean, marginal seas, gulfs, bays and straits of the Indian Ocean include, The climate north of the equator is affected by a monsoon climate. Strong north-east winds blow from October until April, from May until October south, in the Arabian Sea the violent Monsoon brings rain to the Indian subcontinent. In the southern hemisphere, the winds are milder. When the monsoon winds change, cyclones sometimes strike the shores of the Arabian Sea, the Indian Ocean is the warmest ocean in the world. Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, Indian Ocean warming is the largest among the tropical oceans, and about 3 times faster than the warming observed in the Pacific. Research indicates that human induced greenhouse warming, and changes in the frequency, among the few large rivers flowing into the Indian Ocean are the Zambezi, Shatt al-Arab, Indus, Godavari, Krishna, Narmada, Ganges, Brahmaputra, Jubba and Irrawaddy River. The oceans currents are controlled by the monsoon. Two large gyres, one in the northern hemisphere flowing clockwise and one south of the equator moving anticlockwise, during the winter monsoon, however, currents in the north are reversed. Deep water circulation is controlled primarily by inflows from the Atlantic Ocean, the Red Sea, north of 20° south latitude the minimum surface temperature is 22 °C, exceeding 28 °C to the east. Southward of 40° south latitude, temperatures drop quickly, surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia

Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Andaman Sea
–
The sea has been traditionally used for fishery and transportation of goods between the coastal countries and its coral reefs and islands are popular tourist destinations. The fishery and tourist infrastructure was damaged by the 2004 Indian Ocean earthquake. At its southeastern reaches, the Andaman Sea narrows to form the Straits of Malacca, the International Hydrographic Organization defines the limits of the Andaman or Burma Sea as follows, On the Southwest. The Eastern limit of the Bay of Bengal, a line joining Lem Voalan in Siam, and Pedropunt in Sumatra. The average depth of the sea is about 1,000 meters, the northern and eastern parts are shallower than 180 meters due to the silt deposited by the Irrawaddy River. This major river flows into the sea from the north through Myanmar, the western and central areas are 900–3,000 meters deep. Less than 5% of the sea is deeper than 3,000 meters, and in a system of submarine valleys east of the Andaman-Nicobar Ridge, the sea floor is covered with pebbles, gravel and sand. Running in a rough north–south line on the seabed of the Andaman Sea is the boundary between two plates, the Burma Plate and the Sunda Plate. As a result, a basin center was created, which began to form the marginal basin which would become the Andaman Sea. The boundary between two tectonic plates results in high seismic activity in the region. Numerous earthquakes have been recorded, and at least six, in 1797,1833,1861,2004,2005 and 2007, had the magnitude of 8.4 or higher. On December 26,2004, a portion of the boundary between the Burma Plate and the Indo-Australian Plate slipped, causing the 2004 Indian Ocean earthquake. This megathrust earthquake had a magnitude of 9.3, between 1300 and 1600 kilometers of the boundary underwent thrust faulting and shifted by about 20 meters, with the sea floor being uplifted several meters. This rise in the sea floor generated a tsunami with an estimated height of 28 meters that killed approximately 280,000 people along the coast of the Indian Ocean. The initial quake was followed by a series of aftershocks along the arc of the Andaman, the entire event severely damaged the fishing infrastructure. Within the sea, to the east of the main Great Andaman island group, lies Barren Island and this island-volcano is 3 km in diameter and rises 354 meters above the sea level. Its recent activity resumed in 1991 after a period of almost 200 years. It is caused by the subduction of the India Plate beneath the Andaman island arc

Arafura Sea
–
The Arafura Sea lies west of the Pacific Ocean overlying the continental shelf between Australia and Indonesian New Guinea. The Arafura Sea is bordered by Torres Strait and through that the Coral Sea to the east, the Gulf of Carpentaria to the south, the Timor Sea to the west and it is 1,290 kilometres long and 560 kilometres wide. The depth of the sea is primarily 50–80 metres with the depth increasing to the west, as a shallow tropical sea, its waters are a breeding ground for tropical cyclones. The sea lies over the Arafura Shelf, part of the Sahul Shelf, the combined landmass formed the continent of Sahul. The International Hydrographic Organization defines the Arafura Sea as being one of the waters of the East Indian Archipelago, the IHO defines its limits as follows, On the North. The Southeastern limit of the Ceram Sea and the Eastern limit of the Banda Sea, the Southwest coast of New Guinea from Karoefa to the entrance to the Bensbak River, and thence a line to the Northwest extreme of York Peninsula, Australia. By the North coast of Australia from the Northwest extreme of York Peninsula to Cape Don, a line from Cape Don to Tanjong Aro Oesoe, the Southern point of Selaroe. The seas name appeared in George Windsor Earls 1837 Sailing Directions for the Arafura Sea which he compiled from the narratives of Lieuts, Kolff and Modera of the Dutch Navy. The Arafura Sea name is from the name for the people of mountains in the Moluccas as identified by Dutch Lieutenants Kolff. Thomas Forrest sailed thru the Moluccas in 1775 and retailed reports of Harafora people living in the end of New Guinea in subordination to the Papuas. The geographer Conrad Malte-Brun repeated Forrests reports of a race of Haraforas, in 1822, the form Horrafora was recorded by John Coulter, in his account of a sojourn in the interior of south-west New Guinea in 1835, and applied to the tribespeople there. Coulter concluded that Papuans and Horraforas were two races in New Guinea. The Arafura Sea is a fishery resource, particularly for shrimp. Economically important species include Barramundi, grouper, Penaeid shrimp, Nemipteridae fishes, in a world where marine ecosystems and fish stocks are generally collapsing, the Arafura Sea stands out as among the richest marine fisheries in the world. However, the Arafura is coming under more intense pressure from illegal. If this trend persists, the local communities who surround the sea. Increasing economic growth and maintaining environment quality are two challenges to achieve sustainable development in coastal areas of the sea. Established in 2002, the Arafura and Timor Seas Expert Forum seeks to economically and environmentally sustainable management of the seas

Banda Sea
–
The Banda Sea is a sea in the Maluku Islands of Indonesia, connected to the Pacific Ocean but surrounded by hundreds of islands, as well as the Halmahera and Ceram Seas. It is about 1000 km east to west, and about 500 km north to south, the International Hydrographic Organization defines the Banda Sea as being one of the waters of the East Indian Archipelago. The IHO defines its limits as follows, On the North The Southern limits of the Molukka Sea and the Western and Southern limits of the Ceram Sea. Islands bordering the Banda Sea include Sulawesi to the west, Buru, Ambon Island, Seram, Aru Islands, Barat Daya Islands, to the Tanimbar Islands, the Kai Islands and Timor in the East. Although the borders of the sea are hazardous to navigation, with small rocky islands. Island groups within the sea include the Banda Islands, a number of islands in the Banda Sea are active volcanoes including Gunung Api and Manuk in the Banda Islands. The Banda arc is famous for its 180° curvature and is, in Timor, the Banda Sea occupies the main portion of the Banda Sea Plate. The southern margin of the sea consists of island arcs above subduction zones, to the east of the Sunda Trench is the Timor Trough which lies south of Timor, the Tanimbar Trough south of the Tanimbar Islands and the Aru Trough east of the Aru Islands. These trenches are the zone of the Indo-Australian plate beneath the Banda Sea Plate. Fore-arc sediments progressively carried northwards by the Indo-Australian Plate have been folded and faulted forming Timor island, to the northeast lies Seram Island which overlies the subduction of the Birds Head Plate of West Irian. Earthquakes are very frequent in the area, due to the confluence of three tectonic plates - Eurasian, Pacific and Indo-Australian plates. These islands are covered in mostly intact rain forest and home to a number of plants and animals including twenty-one birds. There are only twenty-two mammals on islands including three endemics, the rare dusky pademelon and tomb bat, and an endangered mouse-eared bat. The birdlife is threatened by egg collectors and even more by cats and rodents that have introduced to the islands. Yamdena in the Tanimbar Islands is an example of a large, the base for visiting these islands is by plane or ship from Ambon Island to the north, the largest of the Maluku Islands.

Celebes Sea
–
It extends 420 miles north-south by 520 mi east-west and has a total surface area of 110,000 square miles, to a maximum depth of 20,300 feet. The sea opens southwest through the Makassar Strait into the Java Sea, the Celebes Sea is a piece of an ancient ocean basin that formed 42 million years ago in a locale removed from any landmass. By 20 million years ago, earth crust movement had moved the basin close enough to the Indonesian and Philippine volcanoes to receive emitted debris. By 10 million years ago the Celebes Sea was inundated with continental debris, including coal, which was shed from a young mountain on Borneo. The border between the Celebes and the Sulu Sea is at the Sibutu-Basilan Ridge, strong ocean currents, deep sea trenches and seamounts, combined with active volcanic islands, result in complex oceanographic features. It has been agreed that north of the line will be under the jurisdiction of the Philippines. The International Hydrographic Organization defines the Celebes Sea as being one of the waters of the East Indian Archipelago, the IHO defines its limits as follows, On the North. The Southern limit of Sulu Sea and the Southwest coast of Mindanao, a line from Tinaca Point, the Southern point of Mindanao, to the North point of pulau Sangihe Besar thence through the pulau-pulau Sangihe to Tanjung Puisan, the Northeast extreme of Celebes. The North coast of Celebes between tanjung Puisan and tanjung Binar and thence a line to Tanjung Mangkalihat in Borneo, the Northern limit of Makassar Strait, the East coast of Borneo between Tanjung Mangkalihat and Tanjong Labian, the Southern limit of the Sulu Sea. The Celebes Sea is home to a variety of fish. Tuna and yellowfin tuna are also abundant, in addition to high abundance of fish caught in the Celebes sea, this sea also yields other aquatic products like sea tang. The Celebes Sea is an important sea route for regional trade, the sea is also popular for scuba diving and luxury ocean cruising. The Celebes Sea is underlain by a plate with a mid oceanic spreading in the center part. This place is subducted to the south and north, a number of seismic surveys and research drillings were done in this area to gather geological information. The geology of Sulawesi Sea has been described in the Geology of Indonesia Wikibook, exploring the Inner Space of the Celebes Sea 2007 - A rich collection of images, video and audio podcast
