Cameroon line
–
The Cameroon line is a 1,600 km chain of volcanoes. The islands, which span the equator, have tropical climates and are home to many unique plant, the mainland mountain regions are much cooler than the surrounding lowlands, and also contain unique and ecologically important environments. The Cameroon volcanic line is unusual in extending through both the ocean and the continental crust. Various hypotheses have advanced by different geologists to explain the line. In the Gulf of Guinea, the Cameroon line consists of six offshore volcanic swells that have formed islands or seamounts, from the southwest to the northeast the island groups are Pagalu, São Tomé, Príncipe and Bioko. Two large seamounts lie between São Tomé and Príncipe, and between Principe and Bioko, on the mainland, the line starts with Mount Cameroon and extends northeast in a range known as the Western High Plateau, home to the Cameroonian Highlands forests. Volcanic swells further inland are Manengouba, Bamboutu and the Oku Massif, east of Oku there are further volcanic mountains in the Ngaoundere Plateau, some of which appear to have similar origins. The southernmost island in the chain is Annobón, also known as Pagalu and it is an extinct volcano that rises from deep water to 598 m above sea level. The average temperature is 26.1 °C, with seasonal variation. Most rain falls from November to May, with annual precipitation averaging 1,196 mm - less than on the mainland, Annobón has lush valleys and steep mountains, covered with rich woods and luxuriant vegetation. The island belongs to Equatorial Guinea, the small population lives in one community, practicing some agriculture but mainly living by fishing. São Tomé Island is 854 km2 in area, lying almost on the equator. The entire island is a shield volcano which rises from the floor of the Atlantic Ocean, over 3,000 m below sea level. The oldest rock on Sao Tome is 13 million years old, most of the lava erupted on São Tomé over the last million years has been basalt. The youngest dated rock on the island is about 100,000 years old, due to the prevailing southwesterly winds, there is great variability in rainfall. In the rain shadow to the northeast of Sao Tome the vegetation is dry savannah, by contrast, the lush south and west of the island receive about 6 m of rain, mostly falling in March and April. The climate is hot and humid with the season from October to May. The higher slopes of the island are forested and form part of the Obo National Park, São Tomé has never been connected to Africa, and therefore has many unique plants and birds

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

Niger river
–
The Niger River is the principal river of western Africa, extending about 4,180 km. Its drainage basin is 2,117,700 km2 in area and its source is in the Guinea Highlands in southeastern Guinea. The Niger is the third-longest river in Africa, exceeded only by the Nile and its main tributary is the Benue River. The Scottish explorer Mungo Park was the first Westerner known to have travelled to the portion of the Niger River. The earliest use of the name Niger for the river is by Leo Africanus in his Della descrittione dell’Africa et delle cose notabili che iui sono published in Italian in 1550, the name may come from Berber phrase ger-n-ger meaning river of rivers. As Timbuktu was the end of the principal Trans-Saharan trade route to the western Mediterranean. When European colonial powers began to send ships along the West coast of Africa in the 16th and 17th centuries, the Niger Delta, pouring into the Atlantic through mangrove swamps and thousands of distributaries along more than 160 kilometres, was thought to be no more than coastal wetlands. The Niger River is a clear river, carrying only a tenth as much sediment as the Nile because the Nigers headwaters lie in ancient rocks that provide little silt. Like the Nile, the Niger floods yearly, this begins in September, peaks in November, an unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region of braided streams, marshes, and lakes the size of Belgium, the river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, the average loss is estimated at 31 km3/year, but varies considerably between years. The river is joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km3/year before the 1980s, the most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The Niger takes one of the most unusual routes of any major river and this strange geography apparently came about because the Niger River is two ancient rivers joined together. Over time upstream erosion by the lower Niger resulted in capture of the upper Niger by the lower Niger. The northern part of the river, known as the Niger bend, is an important area because it is the major river and this made it the focal point of trade across the western Sahara, and the centre of the Sahelian kingdoms of Mali and Gao. The surrounding Niger River Basin is one of the distinct physiographic sections of the Sudan province, the origin of the rivers name remains unclear. What is clear is that Niger was an appellation applied in the Mediterranean world from at least the Classical era, when knowledge of the area by Europeans was slightly better than fable

Atlantic Ocean
–
The Atlantic Ocean is the second largest of the worlds oceans with a total area of about 106,460,000 square kilometres. It covers approximately 20 percent of the Earths surface and about 29 percent of its surface area. It separates the Old World from the New World, the Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. The Equatorial Counter Current subdivides it into the North Atlantic Ocean, in contrast, the term Atlantic originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of years ago. The term Aethiopian Ocean, derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century, many Irish or British people refer to the United States and Canada as across the pond, and vice versa. The Black Atlantic refers to the role of ocean in shaping black peoples history. Irish migration to the US is meant when the term The Green Atlantic is used, the term Red Atlantic has been used in reference to the Marxian concept of an Atlantic working class, as well as to the Atlantic experience of indigenous Americans. Correspondingly, the extent and number of oceans and seas varies, the Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea, to the east, the boundaries of the ocean proper are Europe, the Strait of Gibraltar and Africa. In the southeast, the Atlantic merges into the Indian Ocean, the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean, the Atlantic has irregular coasts indented by numerous bays, gulfs, and seas. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23. 5% of the ocean and has a volume of 310,410,900 km3 or 23. 3%. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3, the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S, the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2000 m along most of its length, the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other

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

Ivory Coast
–
Ivory Coast or Côte dIvoire, officially the Republic of Côte dIvoire, is a country located in West Africa. Ivory Coasts political capital is Yamoussoukro, and its economic capital and its bordering countries are Guinea and Liberia in the west, Burkina Faso and Mali in the north, and Ghana in the east. The Gulf of Guinea is located south of Ivory Coast, prior to its colonization by Europeans, Ivory Coast was home to several states, including Gyaaman, the Kong Empire, and Baoulé. Two Anyi kingdoms, Indénié and Sanwi, attempted to retain their identity through the French colonial period. Ivory Coast became a protectorate of France in 1843–1844 and was formed into a French colony in 1893 amid the European scramble for Africa. Ivory Coast achieved independence in 1960, led by Félix Houphouët-Boigny, the country maintained close political and economic association with its West African neighbors while at the same time maintaining close ties to the West, especially France. Since the end of Houphouët-Boignys rule in 1993, Ivory Coast has experienced one coup détat, in 1999, the first took place between 2002 and 2007 and the second during 2010-2011. As a result, in 2000, the adopted a new Constitution. Ivory Coast is a republic with an executive power invested in its President. Through the production of coffee and cocoa, the country was a powerhouse in West Africa during the 1960s and 1970s. Ivory Coast went through a crisis in the 1980s, contributing to a period of political and social turmoil. Changing into the 21st-century Ivorian economy is largely market-based and still heavily on agriculture. The official language is French, with indigenous languages also widely used, including Baoulé, Dioula, Dan, Anyin. In total there are around 78 languages spoken in Ivory Coast, popular religions include Islam, Christianity, and various indigenous religions. Originally, Portuguese and French merchant-explorers in the 15th and 16th centuries divided the west coast of Africa, very roughly, there was also a Pepper Coast also known as the Grain Coast, a Gold Coast, and a Slave Coast. Like those, the name Ivory Coast reflected the major trade occurred on that particular stretch of the coast. One can find the name Cote de Dents regularly used in older works and it was used in Ducketts Dictionnaire and by Nicolas Villault de Bellefond, for examples, although Antoine François Prévost used Côte dIvoire. In the 19th century, usage switched to Côte dIvoire and it retained the name through French rule and independence in 1960

Ghana
–
Ghana, officially the Republic of Ghana, is a unitary presidential constitutional democracy, located along the Gulf of Guinea and Atlantic Ocean, in the subregion of West Africa. Spanning a land mass of 238,535 km², Ghana is bordered by the Ivory Coast in the west, Burkina Faso in the north, Togo in the east, Ghana means Warrior King in the Soninke language. The territory of present-day Ghana has been inhabited for a millennium, numerous kingdoms and empires emerged over the centuries, of which the most powerful was the Kingdom of Ashanti. Beginning in the 15th century, numerous European powers contested the area for trading rights, following over a century of native resistance, Ghanas current borders were established by the 1900s as the British Gold Coast. On 6 March 1957, it became the first sub-Saharan African nation to become independent of European colonisation, a multicultural nation, Ghana has a population of approximately 27 million, spanning a variety of ethnic, linguistic and religious groups. Five percent of the population practices traditional faiths,71. 2% adhere to Christianity and 17. 6% are Muslim and its diverse geography and ecology ranges from coastal savannahs to tropical jungles. Ghana is a country led by a president who is both head of state and head of the government. Ghanas economy is one of the strongest and most diversified in Africa, following a century of relative stability. Ghanas growing economic prosperity and democratic political system have made it a power in West Africa. It is a member of the Non-Aligned Movement, the African Union, the Economic Community of West African States, Group of 24, Ghana was already recognized as one of the great kingdoms in Bilad el-Sudan by the ninth century. Ghana was inhabited in the Middle Ages and the Age of Discovery by a number of ancient predominantly Akan kingdoms in the Southern and this included the Ashanti Empire, the Akwamu, the Bonoman, the Denkyira, and the Mankessim Kingdom. Until the 11th century, the majority of modern Ghanas territorial area was unoccupied and uninhabited by humans. Although the area of present-day Ghana in West Africa has experienced many population movements, by the early 11th century, the Akans were firmly established in the Akan state called Bonoman, for which the Brong-Ahafo Region is named. From the 13th century, Akans emerged from what is believed to have been the Bonoman area, to create several Akan states of Ghana and these states included Bonoman, Ashanti, Denkyira, Mankessim Kingdom, and Akwamu Eastern region. By the 19th century, the territory of the part of Ghana was included in the Kingdom of Ashanti. The Kingdom of Ashanti government operated first as a loose network, prior to Akan contact with Europeans, the Akan Ashanti people created an advanced economy based on principally gold and gold bar commodities then traded with the states of Africa. The earliest known kingdoms to emerge in modern Ghana were the Mole-Dagbani states, the Mole-Dagombas came on horseback from present-day Burkina Faso under a single leader, Naa Gbewaa. The death of Naa Gbewaa caused civil war among his children, some of whom broke off and founded separate states including Dagbon, Mamprugu, Mossi, Nanumba, Akan trade with European states began after contact with Portuguese in the 15th century

Togo
–
Togo, officially the Togolese Republic, is a country in West Africa bordered by Ghana to the west, Benin to the east and Burkina Faso to the north. It extends south to the Gulf of Guinea, where its capital Lomé is located, Togo covers 57,000 square kilometres, making it one of the smallest countries in Africa, with a population of approximately 7.5 million. From the 11th to the 16th century, various tribes entered the region from all directions. From the 16th century to the 18th century, the region was a major trading center for Europeans to search for slaves, earning Togo. In 1884, Germany declared Togoland a protectorate, after World War I, rule over Togo was transferred to France. Togo gained its independence from France in 1960, in 1967, Gnassingbé Eyadéma led a successful military coup détat after which he became president. At the time of his death in 2005, Gnassingbé was the leader in modern African history. In 2005, his son Faure Gnassingbé was elected president, Togo is a tropical, sub-Saharan nation, highly dependent on agriculture, with a climate that provides good growing seasons. The official language is French, with other languages spoken in Togo. The largest religious group in Togo consists of those with indigenous beliefs, Togo is a member of the United Nations, African Union, Organisation of Islamic Cooperation, South Atlantic Peace and Cooperation Zone, La Francophonie and Economic Community of West African States. Archaeological finds indicate that ancient tribes were able to produce pottery and that name Togo is translated from Ewe language language as land where lagoons lie. Not much is known of the period before arrival of the Portuguese in 1490, during the period from the 11th century to the 16th century, various tribes entered the region from all directions, the Ewé from the east, and the Mina and Guin from the west. Most of them settled in coastal areas, in 1884, a treaty was signed at Togoville with the King Mlapa III, whereby Germany claimed a protectorate over a stretch of territory along the coast and gradually extended its control inland. Its borders were defined after the capture of hinterland by German forces and signing agreements with France, in 1905, this became the German colony of Togoland. The local population was forced to work, cultivate cotton, coffee and cocoa, a railway and the port of Lomé were built for export of agricultural products. The Germans introduced modern techniques of cultivation of cocoa, coffee and cotton, during the First World War, Togoland was invaded by Britain and France, proclaiming the Anglo-French condominium. On 7 December 1916 the condominium collapsed and Togo was divided into British,20 July 1922 Great Britain received the League of Nations mandate to govern the western part of Togo and France to govern the eastern part. In 1945, the received the right to send three representatives to the French parliament

Republic of Benin
–
Benin, officially the Republic of Benin and formerly Dahomey, is a country in West Africa. It is bordered by Togo to the west, Nigeria to the east, the majority of its population lives on the small southern coastline of the Bight of Benin, part of the Gulf of Guinea in the northernmost tropical portion of the Atlantic Ocean. The capital of Benin is Porto-Novo, but the seat of government is in Cotonou, Benin covers an area of 114,763 square kilometers and its population in 2015 was estimated to be approximately 10.88 million. Benin is a nation, highly dependent on agriculture, with substantial employment. The official language of Benin is French, however, indigenous languages such as Fon and Yoruba are commonly spoken. The largest religious group in Benin is Roman Catholicism, followed closely by Islam, Vodun and this region was referred to as the Slave Coast from as early as the 17th century due to the large number of slaves shipped to the New World during the Trans-Atlantic slave trade. After slavery was abolished, France took over the country and renamed it French Dahomey, in 1960, Dahomey gained full independence from France, and had a tumultuous period with many different democratic governments, many military coups and military governments. A Marxist–Leninist state called the Peoples Republic of Benin existed between 1975 and 1990, in 1991, it was replaced by the current multi-party Republic of Benin. During the colonial period and at independence, the country was known as Dahomey, on 30 November 1975 it was renamed to Benin, after the body of water on which the country lies—the Bight of Benin—which, in turn, had been named after the Benin Empire. The country of Benin has no connection to Benin City in modern Nigeria, the form Benin is the result of a Portuguese corruption of the city of Ubinu. The new name, Benin, was chosen for its neutrality, the current country of Benin combines three areas which had different political and ethnic systems prior to French colonial control. Before 1700, there were a few important city states along the coast, the situation changed in the 1600s and early 1700s as the Kingdom of Dahomey, which was of Fon ethnicity, was founded on the Abomey plateau and began taking over areas along the coast. The Dahomey Kingdom was known for its culture and traditions, young boys were often apprenticed to older soldiers, and taught the kingdoms military customs until they were old enough to join the army. This emphasis on preparation and achievement earned Dahomey the nickname of black Sparta from European observers. The kings of Dahomey sold their war captives into transatlantic slavery, by about 1750, the King of Dahomey was earning an estimated £250,000 per year by selling Africans to the European slave-traders. Court protocols, which demanded that a portion of war captives from the many battles be decapitated, decreased the number of enslaved people exported from the area. The number went from 102,000 people per decade in the 1780s to 24,000 per decade by the 1860s, the decline was partly due to the banning of the trans-Atlantic slave trade by Britain and other countries. This decline continued until 1885, when the last slave ship departed from the coast of the present-day Benin Republic bound for Brazil, a former Portuguese colony, the capitals name Porto-Novo is of Portuguese origin, meaning New Port

Cameroon
–
Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It is bordered by Nigeria to the west, Chad to the northeast, the Central African Republic to the east, and Equatorial Guinea, Gabon, Cameroons coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. French and English are the languages of Cameroon. The country is referred to as Africa in miniature for its geological and cultural diversity. Natural features include beaches, deserts, mountains, rainforests, the country is well known for its native styles of music, particularly makossa and bikutsi, and for its successful national football team. Early inhabitants of the territory included the Sao civilisation around Lake Chad, portuguese explorers reached the coast in the 15th century and named the area Rio dos Camarões, which became Cameroon in English. Fulani soldiers founded the Adamawa Emirate in the north in the 19th century, Cameroon became a German colony in 1884 known as Kamerun. After World War I, the territory was divided between France and the United Kingdom as League of Nations mandates, the Union des Populations du Cameroun political party advocated independence, but was outlawed by France in the 1950s, leading to the Cameroonian Independence War. It waged war on French and UPC militant forces until 1971, in 1960, the French-administered part of Cameroon became independent as the Republic of Cameroun under President Ahmadou Ahidjo. The southern part of British Cameroons federated with it in 1961 to form the Federal Republic of Cameroon, the federation was abandoned in 1972. The country was renamed the United Republic of Cameroon in 1972, Cameroon enjoys relatively high political and social stability. This has permitted the development of agriculture, roads, railways, nevertheless, large numbers of Cameroonians live in poverty as subsistence farmers. Power lies firmly in the hands of the president since 1982, Paul Biya. The English-speaking territories of Cameroon have grown increasingly alienated from the government, politicians and civil society in English-speaking regions have called for greater decentralization and even complete separation or independence from the former French-governed territories. The territory of present-day Cameroon was first settled during the Neolithic Era, the longest continuous inhabitants are groups such as the Baka. From here, Bantu migrations into eastern, southern, and central Africa are believed to have originated about 2,000 years ago, the Sao culture arose around Lake Chad c. AD500 and gave way to the Kanem and its successor state, kingdoms, fondoms, and chiefdoms arose in the west. Portuguese sailors reached the coast in 1472 and they noted an abundance of the ghost shrimp Lepidophthalmus turneranus in the Wouri River and named it Rio dos Camarões, which became Cameroon in English

Equatorial Guinea
–
Equatorial Guinea, officially the Republic of Equatorial Guinea, is a country located in Central Africa, with an area of 28,000 square kilometres. Formerly the colony of Spanish Guinea, its post-independence name evokes its location near both the Equator and the Gulf of Guinea, Equatorial Guinea is the only sovereign African state in which Spanish is an official language. As of 2015, the country has an population of over 1.2 million. Equatorial Guinea consists of two parts, an insular and a mainland region, the insular region consists of the islands of Bioko in the Gulf of Guinea and Annobón, a small volcanic island south of the equator. Bioko Island is the northernmost part of Equatorial Guinea and is the site of the countrys capital, the island nation of São Tomé and Príncipe is located between Bioko and Annobón. The mainland region, Río Muni, is bordered by Cameroon on the north and Gabon on the south and it is the location of Bata, Equatorial Guineas largest city, and Oyala, the countrys planned future capital. Rio Muni also includes several small islands, such as Corisco, Elobey Grande. The country is a member of the African Union, Francophonie, since the mid-1990s, Equatorial Guinea has become one of sub-Saharan Africas largest oil producers. The country ranks 144th on the UNs 2014 Human Development Index, the UN says that less than half of the population has access to clean drinking water and that 20% of children die before reaching the age of five. Reporters Without Borders ranks President Teodoro Obiang Nguema Mbasogo among its predators of press freedom, the report rates Equatorial Guinea as a Tier 3 country, the lowest ranking, Countries whose governments do not fully comply with the minimum standards and are not making significant efforts to do so. Pygmies probably once lived in the region that is now Equatorial Guinea. Bantu migrations between the 18th and 19th centuries brought the coastal ethno-linguistic groups as well as the Fang people, elements of the latter may have generated the Bubi, who migrated from Cameroon to Río Muni and Bioko in several waves and succeeded former Neolithic populations. The Annobón population, originally native to Angola, was introduced by the Portuguese via São Tomé island, the Portuguese explorer Fernando Pó, seeking a path to India, is credited as being the first European to discover the island of Bioko in 1472. He called it Formosa, but it took on the name of its European discoverer. The islands of Fernando Pó and Annobón were colonized by Portugal in 1474, Spain thereby tried to gain access to a source of slaves controlled by British merchants. Between 1778 and 1810, the territory of Equatorial Guinea was administered by the Viceroyalty of the Río de la Plata, based in Buenos Aires. From 1827 to 1843, the United Kingdom had a base on Bioko to combat the slave trade, in 1844, on restoration of Spanish sovereignty, the area became known as the Territorios Españoles del Golfo de Guinea. Spain had neglected to occupy the area in the Bight of Biafra to which it had right by treaty

Gabon
–
Gabon, officially the Gabonese Republic, is a sovereign state on the west coast of Central Africa. Located on the equator, Gabon is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly 270,000 square kilometres and its capital and largest city is Libreville. Since its independence from France in 1960, Gabon has had three presidents, in the early 1990s, Gabon introduced a multi-party system and a new democratic constitution that allowed for a more transparent electoral process and reformed many governmental institutions. Gabon was also a member of the United Nations Security Council for the 2010–2011 term. GDP grew by more than 6% per year from 2010 to 2012, however, because of inequality in income distribution, a significant proportion of the population remains poor. Gabons name originates from gabão, Portuguese for cloak, which is roughly the shape of the estuary of the Komo River by Libreville, the earliest inhabitants of the area were Pygmy peoples. They were largely replaced and absorbed by Bantu tribes as they migrated, in the 15th century, the first Europeans arrived. By the 18th century, a Myeni speaking kingdom known as Orungu formed in Gabon, on February 10,1722, Bartholomew Roberts, a Welsh pirate known as Black Bart, died at sea off Cape Lopez. He raided ships off the Americas and West Africa from 1719 to 1722, French explorer Pierre Savorgnan de Brazza led his first mission to the Gabon-Congo area in 1875. He founded the town of Franceville, and was later colonial governor, several Bantu groups lived in the area that is now Gabon when France officially occupied it in 1885. In 1910, Gabon became one of the four territories of French Equatorial Africa, in World War II, the Allies invaded Gabon in order to overthrow the pro-Vichy France colonial administration. The territories of French Equatorial Africa became independent on August 17,1960, the first president of Gabon, elected in 1961, was Léon Mba, with Omar Bongo Ondimba as his vice president. However, when Mba dissolved the National Assembly in January 1964 to institute one-party rule, French paratroopers flew in within 24 hours to restore Mba to power. After a few days of fighting, the coup ended and the opposition was imprisoned, French soldiers still remain in the Camp de Gaulle on the outskirts of Gabons capital to this day. When MBa died in 1967, Bongo replaced him as president, in March 1968, Bongo declared Gabon a one-party state by dissolving the BDG and establishing a new party—the Parti Democratique Gabonais. He invited all Gabonese, regardless of political affiliation, to participate. Bongo was elected President in February 1975, in April 1975, the position of president was abolished and replaced by the position of prime minister

Congo Republic
–
The Republic of the Congo, also known as the Congo Republic, West Congo, Congo-Brazzaville or simply Congo, is a country located in Central Africa. The region was dominated by Bantu-speaking tribes, who built trade links leading into the Congo River basin, Congo-Brazzaville was formerly part of the French colony of Equatorial Africa. Upon independence in 1960, the colony of French Congo became the Republic of the Congo. The Peoples Republic of the Congo was a Marxist–Leninist one-party state from 1970 to 1991, Bantu-speaking peoples who founded tribes during the Bantu expansions largely displaced and absorbed the earliest inhabitants of the region, the Pygmy people, about 1500 BC. Several Bantu kingdoms—notably those of the Kongo, the Loango, the Portuguese explorer Diogo Cão reached the mouth of the Congo in 1484. Commercial relationships quickly grew between the inland Bantu kingdoms and European merchants who traded various commodities, manufactured goods, the area north of the Congo River came under French sovereignty in 1880 as a result of Pierre de Brazzas treaty with King Makoko of the Bateke. This Congo Colony became known first as French Congo, then as Middle Congo in 1903, in 1908, France organized French Equatorial Africa, comprising Middle Congo, Gabon, Chad, and Oubangui-Chari. The French designated Brazzaville as the federal capital, economic development during the first 50 years of colonial rule in Congo centered on natural-resource extraction. The methods were brutal, construction of the Congo–Ocean Railroad following World War I has been estimated to have cost at least 14,000 lives. During the Nazi occupation of France during World War II, Brazzaville functioned as the capital of Free France between 1940 and 1943. The Brazzaville Conference of 1944 heralded a period of reform in French colonial policy. Congo benefited from the expansion of colonial administrative and infrastructure spending as a result of its central geographic location within AEF. It also received a local legislature after the adoption of the 1946 constitution that established the Fourth Republic, during these reforms, Middle Congo became known as the Republic of the Congo in 1958 and published its first constitution in 1959. Antagonism between the pro-Opangault Mbochis and the pro-Youlou Balalis resulted in a series of riots in Brazzaville in February 1959, the Republic of the Congo received full independence from France on 15 August 1960. Fulbert Youlou ruled as the countrys first president until labour elements, the Congolese military took charge of the country briefly and installed a civilian provisional government headed by Alphonse Massamba-Débat. Resentment and bitterness between the Baali and the Mbochi peoples brought upheaval in Brazzaville, the French army arrived to quell the turmoil. New elections took place in April 1959, by the time the Congo became independent, Jacques Opangault, the former opponent of Youlou, agreed to serve under him. Youlou became the first President of the Republic of the Congo, since the political tension was so high in Pointe-Noire, Youlou moved the capital to Brazzaville

DR Congo
–
The Democratic Republic of the Congo, also known as DR Congo, DRC, DROC, East Congo, Congo-Kinshasa, or simply the Congo is a country located in Central Africa. From 1971 to 1997 it was named, and is still called, Zaire. It is the second-largest country in Africa by area and eleventh largest in the world, the Congolese Civil Wars, which began in 1996, brought about the end of Mobutu Sese Sekos 32-year reign and devastated the country. These wars ultimately involved nine African nations, multiple groups of UN peacekeepers and twenty armed groups, besides the capital, Kinshasa, the other major cities, Lubumbashi and Mbuji-Mayi, are both mining communities. DR Congos largest export is raw minerals, with China accepting over 50% of DRCs exports in 2012, as of 2015, according to the Human Development Index, DR Congo has a low level of human development, ranking 176 out of 187 countries. The country was known officially as the Democratic Republic of the Congo from 1965 to 27 October 1971, in 1992, the Sovereign National Conference voted to change the name of the country to the Democratic Republic of the Congo, but the change was not put into practice. The countrys name was restored by former president Laurent-Désiré Kabila following the fall of longtime dictator Mobutu Sese Seko in 1997, some historians think that Bantu peoples began settling in the extreme northwest of Central Africa at the beginning of the 5th century and then gradually started to expand southward. Their propagation was accelerated by the transition from Stone Age to Iron Age techniques, the people living in the south and southwest were mostly San Bushmen and hunter-gatherer groups, whose technology involved only minimal use of metal technologies. The development of tools during this time period revolutionized agriculture. This led to the displacement of the groups in the east and southeast. The 10th century marked the expansion of the Bantu in West-Central Africa. Rising populations soon made intricate local, regional and foreign commercial networks that traded mostly in salt, iron. Belgian exploration and administration took place from the 1870s until the 1920s and it was first led by Sir Henry Morton Stanley, who undertook his explorations under the sponsorship of King Leopold II of Belgium. The eastern regions of the precolonial Congo were heavily disrupted by constant slave raiding, mainly from Arab–Swahili slave traders such as the infamous Tippu Tip, Leopold had designs on what was to become the Congo as a colony. Leopold formally acquired rights to the Congo territory at the Conference of Berlin in 1885 and he named it the Congo Free State. Leopolds rėgime began various infrastructure projects, such as construction of the railway ran from the coast to the capital of Leopoldville. Nearly all such projects were aimed at making it easier to increase the assets which Leopold. In the Free State, colonists brutalized the local population into producing rubber, for which the spread of automobiles, rubber sales made a fortune for Leopold, who built several buildings in Brussels and Ostend to honor himself and his country

Angola
–
Angola /æŋˈɡoʊlə/, officially the Republic of Angola, is a country in Southern Africa. It is the seventh-largest country in Africa and is bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to west. The exclave province of Cabinda has borders with the Republic of the Congo, the capital and largest city of Angola is Luanda. In the 19th century, European settlers slowly and hesitantly began to themselves in the interior. As a Portuguese colony, Angola did not encompass its present borders until the early 20th century, following resistance by groups such as the Cuamato, the Kwanyama and the Mbunda. Independence was achieved in 1975 under a communist one-party state backed by the Soviet Union, however, the country soon descended into an even lengthier civil war that lasted until 2002. It has since become a relatively stable presidential republic. Angola has vast mineral and petroleum reserves, and its economy is among the fastest growing in the world, Angolas economic growth is highly uneven, with the majority of the nations wealth concentrated in a disproportionately small sector of the population. Angola is a state of the United Nations, OPEC, African Union, the Community of Portuguese Language Countries, the Latin Union. A highly multiethnic country, Angolas 25.8 million people span various tribal groups, customs, Angolan culture reflects centuries of Portuguese rule, namely in the predominance of the Portuguese language and the Catholic Church, combined with diverse indigenous influences. The name Angola comes from the Portuguese colonial name Reino de Angola, the toponym was derived by the Portuguese from the title ngola held by the kings of Ndongo. Ndongo was a kingdom in the highlands, between the Kwanza and Lukala Rivers, nominally tributary to the king of Kongo but which was seeking greater independence during the 16th century, modern Angola was populated predominantly by nomadic Khoi and San prior to the first Bantu migrations. The Khoi and San peoples were neither pastoralists nor cultivators, following a hunter-gatherer lifestyle and they were displaced by Bantu peoples arriving from the north, some of whom likely originated in northwestern Nigeria. Bantu speakers introduced the cultivation of bananas and taro, as well as large herds, to Angolas central highlands. During this time, the Bantu established a number of entities in most of what today comprises Angola. To its south lay the Kingdom of Ndongo, from which the area of the later Portuguese colony was known as Dongo. The region now known as Angola was reached by the Portuguese explorer Diogo Cão in 1484, the year before, the Portuguese had established relations with the Kongo, which stretched at the time from modern Gabon in the north to the Kwanza River in the south. The Portuguese established their primary trading post at Soyo, which is now the northernmost city in Angola apart from the Cabinda exclave

Bioko
–
Bioko is an island 32 km off the west coast of Africa, and the northernmost part of Equatorial Guinea. Its population was 334,463 at the 2015 Census and it covers an area of 2,017 km2, the island is located off Cameroon, in the Bight of Bonny portion of the Gulf of Guinea. Its geology is volcanic, its highest peak is Pico Basile at 3,012 m, Bioko has a total area of 2,017 km2. It is 70 km long from NNE to SSW and about 32 km across and it is volcanic and very mountainous with the highest peak Pico Basile. It thus resembles neighbouring islands São Tomé and Príncipe, like them, it lies on the Cameroon line. Bioko used to be the end of an attached to the mainland in what is now Cameroon. The island has a population of 334,463 inhabitants and its historic indigenous people are the Bubi people who currently constitute 58% of the population. Other ethnicities include the Fang, the Igbo who constitute 7% of the population, biokos native name is Otcho in the Bube language. The Portuguese navigator Fernão do Pó in 1472 named it Formosa Flora, the island was inhabited in the middle of the first millennium BC by Bantu tribes from the mainland, who formed the Bubi ethnic group. Unlike other islands in the area, Bioko had an indigenous African population, the Bubi speak a Bantu language. The island has probably been inhabited by this or other Bantu-speaking groups since before the 7th century BC, in 1472, the Portuguese navigator Fernão do Pó was the first European to visit the island. In 1494 it was renamed Fernando Pó in his honor after being claimed as a colony by the Portuguese, the Portuguese developed the island for sugarcane crops, and while considered poor quality, the refineries output was such that Fernando Po sugar briefly dominated the trade centres in Europe. In 1642, the Dutch East India Company established trade bases on the island without Portuguese consent and it temporarily centralized from there its slave trade in the Gulf of Guinea. The Portuguese appeared again on the island in 1648, replacing the Dutch Company with one of their own, also dedicated to slave trading and established in its neighbour island Corisco. Parallel with this establishment, the Bubi clans began the process of establishing the core of a new kingdom on the island. During a period when enslavement was increasing in the region, local clans abandoned their coastal settlements, under the 1778 Treaty of El Pardo, Portugal ceded Fernando Po, Annobón, and the Guinea coast, Rio Muni, to Spain, together forming modern Equatorial Guinea. The treaty was signed by Queen Mary I of Portugal and King Charles III of Spain, in exchange for territory on the American continent, Spain mounted an expedition to Fernando Po, led by the Conde de Argelejos, who stayed for four months. In October 1778, Spain installed a governor on the island who stayed until 1780, chief Molambo was succeeded by another local leader, Lorite, who was succeeded by Lopoa

Corisco
–
Corisco, or Mandj, is a small island of Equatorial Guinea, located 29 kilometres southwest of the Rio Muni estuary that defines the border with Gabon. Corisco, whose name derives from the Portuguese word for lightning, has an area of just 14 km2, during the Iron Age and prior to the arrival of the Portuguese, the island was densely settled. The most important evidence of occupation comes from the area of Nandá, near the eastern coast. These burials belong to two different periods, Early Iron Age and Middle Iron Age, during the first period, the islanders deposited bundles of human bones and iron implements in shallow pits dug in the sand. During the second period, tombs have been documented where the corpses lied down surrounded by pots, probably containing food, the deceased were interred with their adornments and a few personal possessions. When Portuguese sailors arrived in the Mino Estuary in 1471, they noted that the islands in the area were mainly unpopulated and they named Corisco after lightning, due to the gales their experienced around the island. After more than three centuries of abandonment, when it was visited by European sailors, Corisco was settled by the Benga people. They arrived during the half of the 18th century attracted by the prospects of trade with the Europeans. The island was acquired by Spain in 1843, as a result of an arrangement made by J. J. Lerena y Barry with Benga king Bonkoro I. In general the Spanish paid little attention to Corisco, in the early part of the 20th century it was part of the administration of Elobey, Annobon, and Corisco, and postage stamps were issued under that name. It became a part of Equatorial Guinea upon independence. Corisco and the waters of Corisco Bay have become of interest in recent years for their oil prospects. A consortium of Elf Aquitaine and Petrogab began prospecting in 1981, the area is disputed with Gabon because of the perceived value of the oil. In February 2003, Gabonese Defence Minister Ali-Ben Bongo Ondimba visited the islands, arqueología en el Estuario del Muni.

Arctic Ocean
–
The Arctic Ocean is the smallest and shallowest of the worlds five major oceans. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean, located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter, the summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center uses satellite data to provide a record of Arctic sea ice cover. The Arctic may become ice free for the first time in human history within a few years or by 2040, for much of European history, the north polar regions remained largely unexplored and their geography conjectural. He was probably describing loose sea ice known today as growlers or bergy bits, his Thule was probably Norway, early cartographers were unsure whether to draw the region around the North Pole as land or water. The makers of navigational charts, more conservative than some of the more fanciful cartographers, tended to leave the region blank and this lack of knowledge of what lay north of the shifting barrier of ice gave rise to a number of conjectures. In England and other European nations, the myth of an Open Polar Sea was persistent, john Barrow, longtime Second Secretary of the British Admiralty, promoted exploration of the region from 1818 to 1845 in search of this. In the United States in the 1850s and 1860s, the explorers Elisha Kane, even quite late in the century, the eminent authority Matthew Fontaine Maury included a description of the Open Polar Sea in his textbook The Physical Geography of the Sea. Nevertheless, as all the explorers who travelled closer and closer to the reported, the polar ice cap is quite thick. Fridtjof Nansen was the first to make a crossing of the Arctic Ocean. The first surface crossing of the ocean was led by Wally Herbert in 1969, in a dog sled expedition from Alaska to Svalbard, with air support. The first nautical transit of the pole was made in 1958 by the submarine USS Nautilus. Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean, scientific settlements were established on the drift ice and carried thousands of kilometres by ice floes. In World War II, the European region of the Arctic Ocean was heavily contested, the Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km2, almost the size of Antarctica. The coastline is 45,390 km long and it is surrounded by the land masses of Eurasia, North America, Greenland, and by several islands. It is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea, countries bordering the Arctic Ocean are, Russia, Norway, Iceland, Greenland, Canada and the United States. There are several ports and harbours around the Arctic Ocean In Alaska, in Canada, ships may anchor at Churchill in Manitoba, Nanisivik in Nunavut, Tuktoyaktuk or Inuvik in the Northwest territories

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

Southern Ocean
–
As such, it is regarded as the fourth-largest of the five principal oceanic divisions, smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean. This ocean zone is cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters. By way of his voyages in the 1770s, Captain James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Oceans northern boundary or even existence, considering the part of the Pacific, Atlantic. Others regard the seasonally-fluctuating Antarctic Convergence as the natural boundary, Borders and names for oceans and seas were internationally agreed when the International Hydrographic Bureau, the precusor to the IHO, convened the First International Conference on 24 July 1919. The IHO then published these in its Limits of Oceans and Seas, Australian authorities regard the Southern Ocean as lying immediately south of Australia. Map publishers using the term Southern Ocean on their maps include Hema Maps, Southern Ocean is an obsolete name for the Pacific Ocean or South Pacific, coined by Vasco Núñez de Balboa, the first European to discover it, who approached it from the north. The South Seas is an archaic synonym. A1745 British Act of Parliament established a prize for discovering a Northwest Passage to the Western and Southern Ocean of America, authors using Southern Ocean to name the waters encircling the unknown southern polar regions used varying limits. James Cooks account of his second voyage implies New Caledonia borders it, peacocks 1795 Geographical Dictionary said it lay to the southward of America and Africa, John Payne in 1796 used 40 degrees as the northern limit, the 1827 Edinburgh Gazetteer used 50 degrees. The United Kingdoms South Australia Act 1834 described the waters forming the southern limit of the new colony of South Australia as the Southern Ocean. The Colony of Victorias Legislative Council Act of 1881 delimited part of the division of Bairnsdale as along the New South Wales boundary to the Southern ocean. The limit then followed the west coast of Tasmania southwards to the South East Cape and then went eastwards to Broughton Island, New Zealand, the northern limits of the Southern Ocean were moved southwards in the IHOs 1937 second edition of the Limits of Oceans and Seas. From this edition, much of the northern limit ceased to abut land masses. As is discussed in detail below, prior to the 2002 edition the limits of oceans explicitly excluded the seas lying within each of them. The Great Australian Bight was unnamed in the 1928 edition, and it therefore encompassed former Southern Ocean waters but was technically not inside any of the three adjacent oceans by 1937. To perform direct comparisons of current and former limits of oceans it is necessary to consider, or at least be aware of, the limits of the Atlantic, Pacific and Indian Oceans have therefore been extended South to the Antarctic Continent. The IHO readdressed the question of the Southern Ocean in a survey in 2000, of its 68 member nations,28 responded, and all responding members except Argentina agreed to redefine the ocean, reflecting the importance placed by oceanographers on ocean currents

World Ocean
–
The unity and continuity of the World Ocean, with relatively free interchange among its parts, is of fundamental importance to oceanography. In turn, oceanic waters are interspersed by many smaller seas, gulfs, a global ocean has existed in one form or another on Earth for eons, and the notion dates back to classical antiquity in the form of Oceanus. The contemporary concept of the World Ocean was coined in the early 20th century by the Russian oceanographer Yuly Shokalsky to refer to the ocean that covers. If viewed from the pole of Earth, the Atlantic, Indian. Farther north, the Atlantic opens into the Arctic Ocean, which is connected to the Pacific by the Bering Strait, the Pacific Ocean, the largest of the oceans, also reaches northward from the Southern Ocean to the Arctic Ocean. It spans the gap between Australia and Asia, and the Americas, the Pacific Ocean meets the Atlantic Ocean south of South America at Cape Horn. The Atlantic Ocean, the second largest, extends from the Southern Ocean between the Americas, and Africa and Europe, to the Arctic Ocean, the Atlantic Ocean meets the Indian Ocean south of Africa at Cape Agulhas. The Indian Ocean, the third largest, extends northward from the Southern Ocean to India, the Indian Ocean joins the Pacific Ocean to the east, near Australia. The Arctic Ocean is the smallest of the five and it joins the Atlantic Ocean near Greenland and Iceland and joins the Pacific Ocean at the Bering Strait. It overlies the North Pole, touching North America in the Western Hemisphere, the Arctic Ocean is partially covered in sea ice, the extent of which varies according to the season. The Southern Ocean is an ocean surrounding Antarctica, dominated by the Antarctic Circumpolar Current. The Southern Ocean is partially covered in sea ice, the extent of which according to the season. The Southern Ocean is the second smallest of the five named oceans, plate tectonics, post-glacial rebound and sea level rise continually change the coastline and structure of the world ocean.

Cape Lopez is a 55 km-long peninsula on the coast of west central Africa, in the country of Gabon. It separates the Gulf of Guinea from the South Atlantic Ocean, lying in the delta of the Ogooué River, it shelters the seaport of Port-Gentil. A lighthouse has existed on the Cape since 1897, the current tower was built in 1911 and it is named after the Portuguese explorer Lopes Gonçalves, who reached it about 1474

Cape Palmas
–
Cape Palmas is a headland on the extreme southeast end of the coast of Liberia, West Africa, at the extreme southwest corner of the northern half of the continent. The Cape itself consists of a small, rocky peninsula connected to the mainland by a sandy isthmus, immediately to the west of the peninsula is the estuary of the Hoffman River. Approximately 21 km further along the coast to the east, the Cavalla River empties into the sea and it marks the western limit of the Gulf of Guinea, according to the International Hydrographic Organisation. Approached from the sea, there are several landmarks at the cape, offshore from the estuary of the Hoffman lies the small, oblong shape of Russwurm Island, which was named after the first black governor of Maryland In Africa, John Brown Russwurm. This island is connected to the peninsula by a breakwater, there is also a lighthouse warning of the numerous shoals in the surrounding sea area. Clearly visible from offshore is a building with an enormous golden orb on the roof. Gomes named this geographic feature Cabo das Palmas, i. e. Cape of the Palms, the river was named Rio das Palmas, later to be called the Hoffman River. Interestingly, the name Cape Palmas first appeared on maps of Africa in Latin. The earliest map of Africa with the name Cape Palmas is Cantino planisphere completed in 1502, american-born Episcopal missionary teacher Elizabeth Mars Johnson Thomson taught at Cape Palmas from 1835 until 1862, and died at Cape Palmas in 1864. With Cape Palmas at its center, the colony was granted statehood on February 2,1841, on March 18,1857, the state of Maryland was annexed as a part of the Republic of Liberia, after signing an annexation treaty with the Republic of Liberia. The city of Harper, Liberia extends to the northeast inland along the estuary of the Hoffman, providing a small harbor, the name Cape Palmas is generalized to indicate the entire surrounding region of Maryland County. It is also applied in the vernacular as being virtually synonymous with the county seat

Equator
–
The Equator usually refers to an imaginary line on the Earths surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about 40,075 kilometres long, some 78. 7% lies across water and 21. 3% over land, other planets and astronomical bodies have equators similarly defined. Generally, an equator is the intersection of the surface of a sphere with the plane that is perpendicular to the spheres axis of rotation. The latitude of the Earths equator is by definition 0° of arc, the equator is the only line of latitude which is also a great circle — that is, one whose plane passes through the center of the globe. The plane of Earths equator when projected outwards to the celestial sphere defines the celestial equator, in the cycle of Earths seasons, the plane of the equator passes through the Sun twice per year, at the March and September equinoxes. To an observer on the Earth, the Sun appears to travel North or South over the equator at these times, light rays from the center of the Sun are perpendicular to the surface of the Earth at the point of solar noon on the Equator. Locations on the Equator experience the quickest sunrises and sunsets because the sun moves nearly perpendicular to the horizon for most of the year. The Earth bulges slightly at the Equator, the diameter of the Earth is 12,750 kilometres. Because the Earth spins to the east, spacecraft must also launch to the east to take advantage of this Earth-boost of speed, seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earths axis relative to the plane of revolution. During the year the northern and southern hemispheres are inclined toward or away from the sun according to Earths position in its orbit, the hemisphere inclined toward the sun receives more sunlight and is in summer, while the other hemisphere receives less sun and is in winter. At the equinoxes, the Earths axis is not tilted toward the sun, instead it is perpendicular to the sun meaning that the day is about 12 hours long, as is the night, across the whole of the Earth. Near the Equator there is distinction between summer, winter, autumn, or spring. The temperatures are usually high year-round—with the exception of high mountains in South America, the temperature at the Equator can plummet during rainstorms. In many tropical regions people identify two seasons, the wet season and the dry season, but many places close to the Equator are on the oceans or rainy throughout the year, the seasons can vary depending on elevation and proximity to an ocean. The Equator lies mostly on the three largest oceans, the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean. The highest point on the Equator is at the elevation of 4,690 metres, at 0°0′0″N 77°59′31″W and this is slightly above the snow line, and is the only place on the Equator where snow lies on the ground. At the Equator the snow line is around 1,000 metres lower than on Mount Everest, the Equator traverses the land of 11 countries, it also passes through two island nations, though without making a landfall in either. Starting at the Prime Meridian and heading eastwards, the Equator passes through, Despite its name, however, its island of Annobón is 155 km south of the Equator, and the rest of the country lies to the north

Prime Meridian
–
A prime meridian is a meridian in a geographical coordinate system at which longitude is defined to be 0°. Together, a meridian and its antimeridian form a great circle. This great circle divides the sphere, e. g. the Earth, if one uses directions of East and West from a defined prime meridian, then they can be called Eastern Hemisphere and Western Hemisphere. The most widely used modern meridian is the IERS Reference Meridian and it is derived but deviates slightly from the Greenwich Meridian, which was selected as an international standard in 1884. The notion of longitude was developed by the Greek Eratosthenes in Alexandria, and Hipparchus in Rhodes, but it was Ptolemy who first used a consistent meridian for a world map in his Geographia. The main point is to be comfortably west of the tip of Africa as negative numbers were not yet in use. His prime meridian corresponds to 18°40 west of Winchester today, at that time the chief method of determining longitude was by using the reported times of lunar eclipses in different countries. Ptolemys Geographia was first printed with maps at Bologna in 1477, but there was still a hope that a natural basis for a prime meridian existed. The Tordesillas line was settled at 370 leagues west of Cape Verde. This is shown in Diogo Ribeiros 1529 map, in 1541, Mercator produced his famous 41 cm terrestrial globe and drew his prime meridian precisely through Fuertaventura in the Canaries. His later maps used the Azores, following the magnetic hypothesis, but by the time that Ortelius produced the first modern atlas in 1570, other islands such as Cape Verde were coming into use. In his atlas longitudes were counted from 0° to 360°, not 180°W to 180°E as is usual today and this practice was followed by navigators well into the 18th century. In 1634, Cardinal Richelieu used the westernmost island of the Canaries, Ferro, 19°55 west of Paris, the geographer Delisle decided to round this off to 20°, so that it simply became the meridian of Paris disguised. In the early 18th century the battle was on to improve the determination of longitude at sea, between 1765 and 1811, Nevil Maskelyne published 49 issues of the Nautical Almanac based on the meridian of the Royal Observatory, Greenwich. Maskelynes tables not only made the lunar method practicable, they made the Greenwich meridian the universal reference point. In 1884, at the International Meridian Conference in Washington, D. C.22 countries voted to adopt the Greenwich meridian as the meridian of the world. The French argued for a line, mentioning the Azores and the Bering Strait. In October 1884 the Greenwich Meridian was selected by delegates to the International Meridian Conference held in Washington, united States to be the common zero of longitude and standard of time reckoning throughout the world

Latitude
–
In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earths surface. Latitude is an angle which ranges from 0° at the Equator to 90° at the poles, lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the location of features on the surface of the Earth. Without qualification the term latitude should be taken to be the latitude as defined in the following sections. Also defined are six auxiliary latitudes which are used in special applications, there is a separate article on the History of latitude measurements. Two levels of abstraction are employed in the definition of latitude and longitude, in the first step the physical surface is modelled by the geoid, a surface which approximates the mean sea level over the oceans and its continuation under the land masses. The second step is to approximate the geoid by a mathematically simpler reference surface, the simplest choice for the reference surface is a sphere, but the geoid is more accurately modelled by an ellipsoid. The definitions of latitude and longitude on such surfaces are detailed in the following sections. Lines of constant latitude and longitude together constitute a graticule on the reference surface, latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO19111 standard. This is of importance in accurate applications, such as a Global Positioning System, but in common usage, where high accuracy is not required. In English texts the latitude angle, defined below, is denoted by the Greek lower-case letter phi. It is measured in degrees, minutes and seconds or decimal degrees, the precise measurement of latitude requires an understanding of the gravitational field of the Earth, either to set up theodolites or to determine GPS satellite orbits. The study of the figure of the Earth together with its field is the science of geodesy. These topics are not discussed in this article and this article relates to coordinate systems for the Earth, it may be extended to cover the Moon, planets and other celestial objects by a simple change of nomenclature. The primary reference points are the poles where the axis of rotation of the Earth intersects the reference surface, the plane through the centre of the Earth and perpendicular to the rotation axis intersects the surface at a great circle called the Equator. Planes parallel to the plane intersect the surface in circles of constant latitude. The Equator has a latitude of 0°, the North Pole has a latitude of 90° North, the latitude of an arbitrary point is the angle between the equatorial plane and the radius to that point. The latitude, as defined in this way for the sphere, is termed the spherical latitude

Niger River
–
The Niger River is the principal river of western Africa, extending about 4,180 km. Its drainage basin is 2,117,700 km2 in area and its source is in the Guinea Highlands in southeastern Guinea. The Niger is the third-longest river in Africa, exceeded only by the Nile and its main tributary is the Benue River. The Scottish explorer Mungo Park was the first Westerner known to have travelled to the portion of the Niger River. The earliest use of the name Niger for the river is by Leo Africanus in his Della descrittione dell’Africa et delle cose notabili che iui sono published in Italian in 1550, the name may come from Berber phrase ger-n-ger meaning river of rivers. As Timbuktu was the end of the principal Trans-Saharan trade route to the western Mediterranean. When European colonial powers began to send ships along the West coast of Africa in the 16th and 17th centuries, the Niger Delta, pouring into the Atlantic through mangrove swamps and thousands of distributaries along more than 160 kilometres, was thought to be no more than coastal wetlands. The Niger River is a clear river, carrying only a tenth as much sediment as the Nile because the Nigers headwaters lie in ancient rocks that provide little silt. Like the Nile, the Niger floods yearly, this begins in September, peaks in November, an unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region of braided streams, marshes, and lakes the size of Belgium, the river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, the average loss is estimated at 31 km3/year, but varies considerably between years. The river is joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km3/year before the 1980s, the most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The Niger takes one of the most unusual routes of any major river and this strange geography apparently came about because the Niger River is two ancient rivers joined together. Over time upstream erosion by the lower Niger resulted in capture of the upper Niger by the lower Niger. The northern part of the river, known as the Niger bend, is an important area because it is the major river and this made it the focal point of trade across the western Sahara, and the centre of the Sahelian kingdoms of Mali and Gao. The surrounding Niger River Basin is one of the distinct physiographic sections of the Sudan province, the origin of the rivers name remains unclear. What is clear is that Niger was an appellation applied in the Mediterranean world from at least the Classical era, when knowledge of the area by Europeans was slightly better than fable

Volta River
–
The Volta River is a river, primarily flowing in Volta Region and Dagbon in the Northern Region of Ghana, that drains into the Atlantic Ocean at the Gulf of Guinea in Ada. It has three main tributaries—the Black Volta, White Volta and Red Volta, Lake Volta is a reservoir impounded by the Akosombo Dam on the lower Volta River in southern Ghana. It is one of the largest reservoirs in the world and it extends from the Akosombo Dam in southeastern Ghana to the town of Yapei in Dagbon, some 400 kilometres to the north. The reservoirs dam generates electricity for the Volta River Authority, and it may be a resource for irrigation and fish farming. The depth of the river is 45 feet below Lake Volta, the Volta River is crossed by the Adome Bridge below the Akosombo Dam and the reservoir. The Volta River was named by Portuguese gold traders in Ghana and it was their farthest extent of exploration before returning. River of return or “river of bend, ” in reference to its course, impacts of the Akosombo Hydroelectric Project — environmental and human health issues from the Akosombo Dam and Lake Volta

Bight of Benin
–
The Bight of Benin or Bay of Benin is a bight in the Gulf of Guinea area on the western African coast. It extends eastward for about 400 miles from Cape St. Paul to the Nun outlet of the Niger River, to the east it is continued by the Bight of Bonny. The Republic of Benin and this bight were both named after the Benin Empire, on December 25,2003, UTAGE Flight 141 crashed in the Bight. Historical associations with the Atlantic slave trade led to the becoming known as the Slave Coast. The Bight of Benin has an association with slavery, its shore being known as the Slave Coast. An old rhyme says, Beware, beware the Bight of the Benin, a variation goes, Beware beware, the Bight of Benin, one comes out, where fifty went in. This is said to be a jingle or sea shanty about the risk of malaria in the Bight. A third version of the couplet is Beware and take care of the Bight of Benin, theres one comes out for forty goes in. The author Philip McCutchan has written a book titled Beware, beware the Bight of Benin, a short story by Elizabeth Coatsworth, The Forgotten Island, deals with a treasure from Benin. A variation of the rhyme is also mentioned, in Patrick OBrians novel The Commodore, Dr. Maturin recites the rhyme when he learned of his ships destination. Commodore Aubrey checks him, telling him it is bad luck to say out loud on the way in. The rhyme is also quoted in chapter Context of John Brunners novel Stand on Zanzibar. The Bight of Benin is mentioned throughout the novel, david Bramhalls trilogy The Greatest Cape also mentions the rhyme, one of the characters in the first volume, The Black Joke, having been a pirate and a slaver. In 2007, a collection of stories entitled The Bight of Benin. The stories are set in Ghana, Togo, Benin and Nigeria, avant-garde musician Bucketheads song The Bight of Benin off the album Albino Slug is named after this area.

Bight of Bonny
–
The Bight of Biafra is a bight off the West African coast, in the easternmost part of the Gulf of Guinea. The Bight of Biafra extends east of the Bight of Benin from the River Delta of the Niger in the north until it reaches Cape Lopez in Gabon. Besides the Niger River, other rivers reaching the bay are the Cross River, Wouri River, Calabar River, Ndian, Wouri, Sanaga, Nyong River, Ntem, Mbia, Mbini, Muni and Komo River. The main islands in the Bay are Bioko and Príncipe, other important islands are Ilhéu Bom Bom, Ilhéu Caroço, Elobey Grande, countries located at the Bight of Bonny are Nigeria, Cameroon, Equatorial Guinea, and Gabon. The area would, in different steps, merge further via the 12 May 1893 Niger Coast Protectorate,1 January 1900, on 28 February 1906 made into the Colony, from 1 January 1914, it was part of Colony and Protectorate of Nigeria. The bight was renamed within independent Nigeria in 1972, when after the Biafran War, the Nigerian government wanted to remove the name of the term Biafra considered secessionist

Maghreb
–
The Maghreb, or the Greater Maghreb, is usually defined as much or most of the region of western North Africa or Northwest Africa, west of Egypt. Historical terms for the region or various portions of the Maghreb include Mauretania, Numidia, Libya, the term maghrib is Arabic for west, from the verb gharaba. In the strict sense, the definite form al-maghrib denotes the country of Morocco in particular and it identified the westernmost territories that fell to the Islamic conquests of the 7th century. Today, it is a noun for the present region of the Maghreb. The Berber languages alternative term for the region, Tamazgha, has been popularized by Berber activists since the second half of the 20th century. As recently as the late 19th century it was used to refer to the Western Mediterranean region of coastal North Africa in general, and to Algeria, Morocco and Tunisia in particular. The region was unified as an independent political entity during the rule of the Berber kingdom of Numidia. The most enduring rule was that of the local Berber empires of the Almoravids, Almohads, Hammadids, Zirids, Marinids, Saadi, the Ottoman Turks ruled the region as well. Mauritania, Morocco, Tunisia, Algeria, and Libya established the Maghreb Union in 1989 to promote cooperation and it was envisioned initially by Muammar Gaddafi as a superstate. The union included Western Sahara implicitly under Moroccos membership, putting Moroccos long cold war with Algeria to a rest, however, this progress was short-lived, and the union is now frozen. Tensions between Algeria and Morocco over Western Sahara re-emerged strongly, reinforced by the unsolved borderline issue between the two countries and these two main conflicts have hindered progress on the unions joint goals and practically made it inactive as a whole. Around 3,500 BC a tilt in the Earths orbit created a rapid desertification of the Sahara, the Maghreb or western North Africa is believed to have been inhabited by Berbers since from at least 10,000 BC. Maghreb coast ports were predominantly occupied or constructed by the Phoenicians, the main Phoenician settlements centered in the Gulf of Tunis along the North African littoral between the Pillars of Hercules and the Libyan coast east of ancient Cyrenaica. They dominated the trade and intercourse of the Western Mediterranean for centuries, Rome was greatly helped by the defection of King Massinissa and Carthaginians eastern Numidian Massylii client-allies. A century later, the Byzantine emperor Justinian I sent a force under General Belisarius that succeeded in destroying the Vandal kingdom, the Berbers contested outside-the-area control although after the 640s-700 AD period the Arabs controlled the entire region. The Arabs reached the Maghreb in early Umayyad times, Arab expansion and the spread of Islam pushed the development of trans-Saharan trade. While restricted due to the cost and dangers, the trade was highly profitable, commodities traded included such goods as salt, gold, ivory, and slaves. Arab control over the Maghreb was quite weak, various Islamic variations, such as the Ibadis and the Shia, were adopted by some Berbers, often leading to scorning of Caliphal control in favour of their own interpretation of Islam

Elmina
–
Elmina is the first European settlement in West Africa and it has a population of 33,576 people. Prior to the arrival of the Portuguese, the town was called Anomansah, in 1478, near the coast at Elmina was fought a large battle between a Castilian armada of 35 caravels and a Portuguese fleet for hegemony of the Guinea trade. This was the first colonial war among European powers, the town grew around São Jorge da Mina Castle, built by the Portuguese Diogo de Azambuja in 1482 on the site of a town or village called Amankwakurom or Amankwa. It was Portugals West African headquarters for trade and exploitation of African wealth. The original Portuguese interest was gold, with 8,000 ounces shipped to Lisbon from 1487 to 1489,22,500 ounces from 1494 to 1496, and 26,000 ounces by the start of the sixteenth century. Later the port expanded to tens of thousands of slaves channeled through the trading post of Elmina. By 1479, the Portuguese were transporting slaves from as far away as Benin, accounted for 10 percent of the trade in Elmina, the location of Elmina made it a significant site for reprovisioning ships headed south towards the Cape of Good Hope on their way to India. After years of Portuguese wealth on the Elmina Coast, the Dutch learned of the activity taking place through Barent Eriksz of Medenblick, one of the oldest traders. The Dutch West India Company captured it in 1637, in subsequent centuries it was used for the slave trade. The British attacked the city in 1782, but it remained in Dutch hands until 1872, Elmina is also home to Fort Coenraadsburg on St. Jago Hill, built by the Portuguese in 1555 under the name Forte de Santiago, it was used for commerce. In 1637 it was conquered and remained by the Dutch, after the conquest of Elminas main castle, today, Elminas main economic industry is fishing and tourism. Apart from Elmina Castle and Fort Coenraadsburg, the main tourist attractions in Elmina include the Dutch Cemetery, list of sister cities of Elmina, designated by Sister Cities International, Books Diffie, Bailey W. and Winius, George D. - Foundations of the Portuguese Empire, 1415-1580, Volume 1, NEWITT, Malyn- A history of Portuguese overseas expansion, 1400-1668, Routledge, New York,2005.

Gold Coast (region)
–
The Gold Coast is the gold rich region that is now the nation of Ghana on the petroleum sweet crude oil and natural gas rich Gulf of Guinea in West Africa, Africa. The Gold Coast, Slave Coast, Pepper Coast and Ivory Coast were named after the main export resources there, early uses of the term Gold Coast refer literally to the coast and not the interior. It was not until the 19th century that the term came to refer to areas that are far from the coast, the Gold Coast was to the east of the Ivory Coast and to the west of the Slave Coast. Gold Coast was first colonized by the Portuguese, with settlement in 1482 of the Portuguese Gold Coast, in 1642 this became part of the Dutch Gold Coast, which had been colonized by the Dutch since 1598. The Dutch stayed in the region until 1871, when the last of their settlements were taken over by the British Gold Coast, there was also the Brandenburger Gold Coast, which established a colony in the area in 1682. It later became the Prussian Gold Coast, in 1721 it was sold to the Dutch. Sweden also had settlements in Gold Coast, with the Swedish Gold Coast established by the Swedes in 1650, but seized by Denmark in 1663, the Danes had been in the Gold Coast Since 1658. In 1850 all of the settlements became part of the British Gold Coast, the British had taken over all of Gold Coast by 1871. They captured more territory inland in the nineteenth century after the Ashanti wars. In 1957, the territory of Gold Coast was granted independence as Ghana, kwame Nkrumah United Gold Coast Convention and The Big Six Convention Peoples Party

Guinea (region)
–
Guinea is a traditional name for the region of the West coast of Africa that lies along the Gulf of Guinea. It is a naturally moist tropical forest or savanna that stretches along the coast, the etymology of Guinea is uncertain. The term Guinea is extensively used in the 1453 chronicle of Gomes Eanes de Zurara, king John II of Portugal took up the title of Senhor da Guiné from 1483. It is believed the Portuguese borrowed Guineus from the Berber term Ghinawen meaning the burnt people, the Berber terms aginaw and Akal n-Iguinawen mean black and land of the blacks, respectively. A competing theory, first forwarded by Leo Africanus in 1526, claims that Guinea is derived from Djenné, Djenné dominated the gold and salt trade across West Africa, from the 11th century until the 13th century. It is during the period of Djenné dominance that the term Genewah really comes forward into usage in Arab sources, other theories try to connect Guinea to Ghana, but this is less certain. The Ghana Empire is named after the Medieval trading city of Ghanah mentioned already by 11th-century Arab geographers, conversely, it remains possible that both Ghana and Djenné themselves owe their original city names to the Berber appellation for the blacks that lived there. A possible reconciliation of the theories is that the Berber Ghinawen was the source of the Djenné, which in turn gave rise to the Arabic Genewah, historically, the Guinea region was one of the first parts of sub-Saharan Africa to trade with Europeans. In 1478, a Castilian armada of 35 caravels and a Portuguese fleet fought the battle of Guinea in the waters off Elmina, for the hegemony of the Guinea trade. The war ended both with a Portuguese naval victory and the recognition by the Catholic Monarchs of the Portuguese sovereignty over most of the African territories in dispute. This was the first colonial war among European powers, after the Portuguese and Castilians, came the Dutch, French and British. The extensive trade in ivory, gold, and slaves made the region wealthy and these were much smaller than the large states of the wide-open Sahel, but they had far higher population densities and were more centralized politically. The cohesion of these caused the region to show more resistance to European incursions than other areas of Africa. Such resistance, combined with an environment hostile to Europeans. Guinea is often subdivided into Lower Guinea and Upper Guinea, Lower Guinea is one of the most densely populated regions of Africa, covering southern Nigeria, Benin, Togo and stretching into Ghana. It includes the regions as well as the interior. Upper Guinea is far less populated and stretches from Côte dIvoire to Senegal. Within the Republic of Guinea, Lower Guinea refers to the coastal plain

West Africa
–
West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. Early human settlers from northern Holocene societies arrived in West Africa around 12,000 B. C, sedentary farming began in, or around the fifth millennium B. C, as well as the domestication of cattle. By 1500 B. C, ironworking technology allowed an expansion of productivity. Northern tribes developed walled settlements and non-walled settlements that numbered at 400, in the forest region, Iron Age cultures began to flourish, and an inter-region trade began to appear. The desertification of the Sahara and the change of the coast cause trade with upper Mediterranean peoples to be seen. Local leather, cloth, and gold also contributed to the abundance of prosperity for many of the following empires. Also, based on the archaeology of city of Kumbi Saleh in modern-day Mauritania, three great kingdoms were identified in Bilad al-Sudan by the ninth century. They included Ghana, Gao and Kanem, the Sosso Empire sought to fill the void, but was defeated by the Mandinka forces of Sundiata Keita, founder of the new Mali Empire. In the 15th century, the Songhai would form a new dominant state based on Gao, in the Songhai Empire, under the leadership of Sonni Ali, further east, Oyo arose as the dominant Yoruba state and the Aro Confederacy as a dominant Igbo state in modern-day Nigeria. The Kingdom of Nri was a West African medieval state in the present-day southeastern Nigeria, the Kingdom of Nri was unusual in the history of world government in that its leader exercised no military power over his subjects. The kingdom existed as a sphere of religious and political influence over a third of Igboland, the Eze Nri managed trade and diplomacy on behalf of the Nri people, and possessed divine authority in religious matters. The Oyo Empire was a Yoruba empire of what is today Western, established in the 15th century, the Oyo Empire grew to become one of the largest West African states. It rose through the organizational skills of the Yoruba, wealth gained from trade. The Benin Empire was an empire located in what is now southern Nigeria. Its capital was Edo, now known as Benin City, Edo and it should not be confused with the modern-day country called Benin, formerly called Dahomey. The Benin Empire was one of the oldest and most highly developed states in the hinterland of West Africa. Olfert Dapper, a Dutch writer, describing Benin in his book Description of Africa and its craft was the most adored and treasured bronze casting in the history of Africa. It was annexed by the British Empire in 1897 during the invasion, in the early 19th century, a series of Fulani reformist jihads swept across Western Africa

Southern Africa
–
Southern Africa is the southernmost region of the African continent, variably defined by geography or geopolitics, and including several countries. The term southern Africa or Southern Africa, generally includes Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, from a political perspective the region is said to be unipolar with South Africa as a first regional power. It is not used in political, economic or human geography contexts because this definition cuts Mozambique in two, the Southern African Development Community was established in 1980 to facilitate co-operation in the region. Comoros, Madagascar, Malawi, Mayotte, Mauritius, Mozambique, Réunion, Seychelles, Zambia, the Democratic Republic of the Congo and Tanzania, though more commonly reckoned in Central and Eastern Africa, respectively, are occasionally included in Southern Africa as they are SADC members. The terrain of Southern Africa is varied, ranging from forest, the region has both low-lying coastal areas, and mountains. While colonialism has left its mark on the development over the course of history, today poverty, corruption, the pursuit of economic and political stability is an important part of the regions goals, as demonstrated by the SADC. In terms of strength, South Africa is by far the dominant power of the region. South Africas GDP alone is many times greater than the GDPs of all countries in the region. Southern Africa has a diversity of ecoregions including grassland, bushveld, karoo, savannah. It has complex Plateaus that create massive mountain structures along the South African border, there are numerous environmental issues in Southern Africa, including air pollution and desertification. Southern Africa is home to cultures and people. It was once populated by San, Khoikhoi and Pygmies in widely dispersed concentrations, the process of colonization and settling resulted in a significant population of European and Asian descent in many southern African countries. These factors vary from country to country, for example, the Democratic Republic of Congo has favourable climatic and physical conditions, but performs far below its capacity in food provision due to political instability and poor governance. The Republic of South Africa is a food producer and exporter in the region. However this data might not fully capture the reality of a region with high urban populations, urban food security has been noted as an emerging area of development concern in the region, with recent data showing high levels of food insecurity amongst low-income households. In South Africa for example, while over 50% experience hunger, there is only limited data on the other Southern African countries. History of Southern Africa Sub-Saharan Africa Southern Africa

Guinea
–
Guinea /ˈɡɪni/, officially the Republic of Guinea, is a country on the West coast of Africa. Guinea has a population of 10.5 million and an area of 245,860 square kilometres, the president is directly elected by the people and is head of state and head of government. The unicameral Guinean National Assembly is the body of the country. The judicial branch is led by the Guinea Supreme Court, the highest, the country is named after the Guinea region. Guinea is a name for the region of Africa that lies along the Gulf of Guinea. It stretches north through the tropical regions and ends at the Sahel. Guinea is a predominantly Islamic country, with Muslims representing 85 percent of the population, Guineas people belong to twenty-four ethnic groups. French, the language of Guinea, is the main language of communication in schools, in government administration, and the media. Guineas economy is dependent on agriculture and mineral production. It is the second largest producer of bauxite, and has rich deposits of diamonds. The country was at the core of the 2014 Ebola outbreak, human rights in Guinea remain a controversial issue. In 2011 the United States government claimed that torture by security forces, the land that is now Guinea belonged to a series of African empires until France colonized it in the 1890s, and made it part of French West Africa. Guinea declared its independence from France on 2 October 1958, from independence until the presidential election of 2010, Guinea was governed by a number of autocratic rulers. What is now Guinea was on the fringes of the major West African empires, the Ghana Empire is believed to be the earliest of these which grew on trade but contracted and ultimately fell due to the hostile influence of the Almoravids. It was in period that Islam first arrived in the region. The Mali Empire was ruled by Mansa, the most famous being Kankou Moussa, shortly after his reign the Mali Empire began to decline and was ultimately supplanted by its vassal states in the 15th century. The most successful of these was the Songhai Empire, which expanded its power from about 1460 and it continued to prosper until a civil war over succession followed the death of Askia Daoud in 1582. The weakened empire fell to invaders from Morocco at the Battle of Tondibi just three years later, the Moroccans proved unable to rule the kingdom effectively, however, and it split into many small kingdoms

Guinea-Bissau
–
Guinea-Bissau, officially the Republic of Guinea-Bissau, is a country in West Africa. It covers 36,125 square kilometres with a population of 1,704,000. Guinea-Bissau was once part of the kingdom of Gabu, as well as part of the Mali Empire, parts of this kingdom persisted until the 18th century, while a few others were under some rule by the Portuguese Empire since the 16th century. In the 19th century, it was colonized as Portuguese Guinea, upon independence, declared in 1973 and recognised in 1974, the name of its capital, Bissau, was added to the countrys name to prevent confusion with Guinea. Guinea-Bissau has a history of instability since independence, and no elected president has successfully served a full five-year term. Only 14% of the population speaks Portuguese, established as the language in the colonial period. Almost half the population speaks Crioulo, a Portuguese-based creole language, the main religions are African traditional religions and Islam, there is a Christian minority. The countrys per-capita gross domestic product is one of the lowest in the world, Guinea-Bissau was once part of the kingdom of Gabu, part of the Mali Empire, parts of this kingdom persisted until the 18th century. Other parts of the territory in the current country were considered by the Portuguese as part of their empire, Portuguese Guinea was known as the Slave Coast, as it was a major area for the exportation of African slaves by Europeans to the western hemisphere. Early reports of Europeans reaching this area include those of the Venetian Alvise Cadamostos voyage of 1455, the 1479–1480 voyage by Flemish-French trader Eustache de la Fosse, and Diogo Cão. In the 1480s this Portuguese explorer reached the Congo River and the lands of Bakongo, setting up the foundations of modern Angola, some 4200 km down the African coast from Guinea-Bissau. The local African rulers in Guinea, some of whom prospered greatly from the trade, controlled the inland trade. They kept them in the coastal settlements where the trading took place. African communities that fought back against slave traders also distrusted European adventurers, the Portuguese in Guinea were largely restricted to the port of Bissau and Cacheu. A small number of European settlers established isolated farms along Bissaus inland rivers, for a brief period in the 1790s, the British tried to establish a rival foothold on an offshore island, at Bolama. But by the 19th century the Portuguese were sufficiently secure in Bissau to regard the neighbouring coastline as their own special territory, cuba also agreed to supply artillery experts, doctors, and technicians. The PAIGC even managed to acquire a significant anti-aircraft capability in order to defend itself against aerial attack, by 1973, the PAIGC was in control of many parts of Guinea, although the movement suffered a setback in January 1973 when Cabral was assassinated. Independence was unilaterally declared on 24 September 1973, recognition became universal following 25 April 1974 socialist-inspired military coup in Portugal, which overthrew Lisbons Estado Novo regime

New Guinea
–
New Guinea is a large Island in the South West Pacific region. It is the worlds second-largest island, after Greenland, covering an area of 785,753 km2. The island is divided between two countries, Papua New Guinea to the east, and Indonesia to the west, the island has been known by various names. The name Papua was used to refer to parts of the island before contact with the West and its etymology is unclear, one theory states that it is from Tidore, the language used by the Sultanate of Tidore, which controlled parts of the islands coastal region. The name came from papo and ua, which means not united or, ploeg reports that the word papua is often said to derive from the Malay word papua or pua-pua, meaning frizzly-haired, referring to the highly curly hair of the inhabitants of these areas. When the Portuguese and Spanish explorers arrived in the island via the Spice Islands, when the Dutch colonized it as part of Netherlands East Indies, they called it Nieuw Guinea. The name Irian was used in the Indonesian language to refer the island and Indonesian province, the name was promoted in 1945 by Marcus Kaisiepo, brother of the future governor Frans Kaisiepo. It is taken from the Biak language of Biak Island, and means to rise and this name of Irian is the name used in the Biak language and other languages such as Serui, Merauke and Waropen. The name was used until 2001, when the name Papua was again used for the island, the name Irian, which was originally favored by natives, is now considered to be a name imposed by the authority of Jakarta. New Guinea is an island to the north of Australia, and it is isolated by the Arafura Sea to the west and the Torres Strait and Coral Sea to the east. A spine of east–west mountains, the New Guinea Highlands, dominates the geography of New Guinea, stretching over 1,600 km from the head to the tail of the island. The western half of the island of New Guinea contains the highest mountains in Oceania, rising up to 4,884 m high, the tree line is around 4,000 m elevation and the tallest peaks contain permanent equatorial glaciers—which have been retreating since at least 1936. Various other smaller mountain ranges occur both north and west of the central ranges, except in high elevations, most areas possess a warm humid climate throughout the year, with some seasonal variation associated with the northeast monsoon season. At 4,884 metres, Puncak Jaya makes New Guinea the worlds fourth highest landmass, Puncak Mandala, located in Papua, is the second highest peak on the island at 4,760 metres. Puncak Trikora, also in Papua, is 4,750 metres, mount Wilhelm is the highest peak on the PNG side of the border at 4,509 metres. Its granite peak is the highest point of the Bismarck Range, mount Giluwe 4,368 metres is the second highest summit in PNG. It is also the highest volcanic peak in Oceania, another major habitat feature is the vast southern and northern lowlands. Stretching for hundreds of kilometres, these include lowland rainforests, extensive wetlands, savanna grasslands, the southern lowlands are the site of Lorentz National Park, also a UNESCO World Heritage Site

Melanesia
–
Melanesia is a subregion of Oceania extending from the western end of the Pacific Ocean to the Arafura Sea, and eastward to Fiji. The region includes the four countries of Vanuatu, the Solomon Islands, Fiji, the concept among Europeans of Melanesia as a distinct region evolved gradually over time as their expeditions mapped and explored the Pacific. Early European explorers noted the differences among groups of Pacific Islanders. In the first half of the nineteenth century Jean Baptiste Bory de Saint-Vincent, over time, however, Europeans increasingly viewed Melanesia as a distinct cultural, rather than racial, area. Scholars and other commentators disagreed on its boundaries, which were fluid, in the nineteenth century Robert Codrington, a British missionary, produced a series of monographs on the Melanesians based on his long-time residence in the region. He did not include the islands of New Guinea because only some of its people were Melanesians, like Bory de Saint-Vincent, he excluded Australia from Melanesia. It was in works that Codrington introduced the cultural concept of mana to the West. Uncertainty about the delineation and definition of the region continues, the scholarly consensus now includes New Guinea within Melanesia. Ann Chowning wrote in her 1977 textbook on Melanesia that there is no agreement even among anthropologists about the geographical boundaries of Melanesia. In 1998 Paul Sillitoe wrote of Melanesia, it is not easy to define precisely, on geographical, cultural, biological, or any other grounds, where Melanesia ends and the neighbouring regions. It covers populations that have a linguistic, biological and cultural affinity – a certain ill-defined sameness. Both Sillitoe and Chowning include the island of New Guinea in the definition of Melanesia, most of the peoples in Melanesia have established independent countries, are admistered by France or have active independence movements. Many have recently taken up the term Melanesia as a source of identity, stephanie Lawson writes that the term moved from a term of denigration to one of affirmation, providing a positive basis for contemporary subregional identity as well as a formal organisation. For instance, the author Bernard Narokobi wrote about the Melanesian Way as a form of culture that could empower the people of this region. The concept is used in geopolitics. For instance, the Melanesian Spearhead Group preferential trade agreement is a trade treaty among Vanuatu, the Solomon Islands, Papua New Guinea. The people of Melanesia have a distinctive ancestry, the limit of this ancient migration was Sahul, the continent formed when Australia and New Guinea were united by a land bridge as a result of low sea levels. The first migration into Sahul came over 40,000 years ago, a further expansion into the eastern islands of Melanesia came much later, probably between 4000 B. C. and 3000 B. C

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
