Scripps Institution of Oceanography
–
Hundreds of ocean and Earth scientists conduct research with the aid of oceanographic research vessels and shorebased laboratories. Its Old Scripps Building is a U. S. National Historic Landmark, SIO is a department of the University of California, San Diego. The public explorations center of the institution is the Birch Aquarium at Scripps, since becoming part of the University of California in 1912, the institution has expanded its scope to include studies of the physics, chemistry, geology, biology, and climate of Earth. Dr. Margaret Leinen took office as Vice Chancellor for Marine Sciences, Director of Scripps Institution of Oceanography, Scripps publishes explorations now, an e-magazine of ocean and earth science. To seek, teach, and communicate scientific understanding of the oceans, atmosphere, Earth, and other planets for the benefit of society, Scripps Institution of Oceanography was founded in 1903 as the Marine Biological Association of San Diego, an independent biological research laboratory. It was proposed and incorporated by a committee of the San Diego Chamber of Commerce, led by local activist and they fully funded the institution for its first decade. It began institutional life in the boathouse of the Hotel del Coronado located on San Diego Bay and it re-located in 1905 to the La Jolla area on the head above La Jolla Cove, and finally in 1907 to its present location. In 1912 Scripps became part of the University of California and was renamed the Scripps Institution for Biological Research, the name was changed to Scripps Institution of Oceanography in October 1925. The Old Scripps Building, designed by Irving Gill, was declared a National Historic Landmark in 1982, architect Barton Myers designed the current Scripps Building. The institutions research programs encompass biological, physical, chemical, geological, Scripps also studies the interaction of the oceans with both the atmospheric climate and environmental concerns on terra firma. Related to this research, Scripps offers undergraduate and graduate degrees, today, the Scripps staff of 1,300 includes approximately 235 faculty,180 other scientists and some 300 graduate students, with an annual budget of more than $195 million. The institution operates a fleet of three research vessels and the research platform R/P FLIP for oceanographic research. – RV Ellen B.

Call sign
–
In broadcasting and radio communications, a call sign is a unique designation for a transmitter station. In North America, they are used for all FCC licensed transmitters, a call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a stations identity. The use of signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one line linking all railroad stations. In order to time, two-letter identifiers were adopted for this purpose. This pattern continued in operation, radio companies initially assigned two-letter identifiers to coastal stations and stations aboard ships at sea. These were not globally unique, so a company identifier was later added. Merchant and naval vessels are assigned call signs by their national licensing authorities, in the case of states such as Liberia or Panama, which are flags of convenience for ship registration, call signs for larger vessels consist of the national prefix plus three letters. United States merchant vessels are given call signs beginning with the letters W or K while US naval ships are assigned callsigns beginning with N, leisure craft with VHF radios may not be assigned call signs, in which case the name of the vessel is used instead. Ships in the US wishing to have a radio licence anyway are under F. C. C, class SA, Ship recreational or voluntarily equipped. Those calls follow the land mobile format of the initial letter K or W followed by 1 or 2 letters followed by 3 or 4 numbers. U. S. Coast Guard small boats have a number that is shown on both bows in which the first two digits indicate the length of the boat in feet. For example, Coast Guard 47021 refers to the 21st in the series of 47 foot motor lifeboats, the call sign might be abbreviated to the final two or three numbers during operations, for example, Coast Guard zero two one. Call signs in aviation are derived from several different policies, depending upon the type of flight operation, in most countries, unscheduled general aviation flights identify themselves using the call sign corresponding to the aircrafts registration number. In this case, the sign is spoken using the International Civil Aviation Organization phonetic alphabet. Aircraft registration numbers internationally follow the pattern of a country prefix, for example, an aircraft registered as N978CP conducting a general aviation flight would use the call sign November-niner-seven-eight-Charlie-Papa. However, in the United States a pilot of an aircraft would normally omit saying November, at times, general aviation pilots might omit additional preceding numbers and use only the last three numbers and letters. This is especially true at uncontrolled fields when reporting traffic pattern positions, for example, Skyhawk eight-Charlie-Papa, left base

Fresh water
–
Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs, the term sweet water has been used to describe fresh water in contrast to salt water. The term fresh water does not have the meaning as potable water. Much of the fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants. It may also be in contact with the underlying underground water. The majority of water on Earth is in ice caps. The source of almost all water is precipitation from the atmosphere, in the form of mist, rain. Fresh water falling as mist, rain or snow contains materials dissolved from the atmosphere and material from the sea, in some cases this acid rain results in pollution of lakes and rivers. In coastal areas fresh water may contain significant concentrations of salts derived from the sea if windy conditions have lifted drops of seawater into the rain-bearing clouds. This can give rise to elevated concentrations of sodium, chloride, magnesium, significant quantities of iron may be transported in this way including the well-documented transfer of iron-rich rainfall falling in Brazil derived from sand-storms in the Sahara in north Africa. Water is an issue for the survival of all living organisms. Some can use water but many organisms including the great majority of higher plants. Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Freshwater lakes contain about 87% of this surface water, including 29% in the African Great Lakes, 20% in Lake Baikal in Russia, 21% in the North American Great Lakes. Swamps have most of the balance only a small amount in rivers. In areas with no water on the ground surface, fresh water derived from precipitation may, because of its lower density. Most of the fresh water is frozen in ice sheets. Many areas suffer from lack of distribution of water, such as deserts

Capsizing
–
Capsizing or keeling over is when a boat or ship is turned on its side or it is upside down in the water. The act of reversing a capsized vessel is called righting, if a capsized vessel has enough flotation to prevent sinking, it may recover on its own if the stability is such that it is not stable inverted. Vessels of this design are called self-righting, in dinghy sailing, a practical distinction can be made between being knocked down which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the course of use and can usually be recovered by the crew. Some types of dinghy are occasionally deliberately capsized, as capsizing and righting the vessel again can be the fastest means of draining water from the boat, capsizing is an inherent part of dinghy sailing. It is not a question of if but a question of when, for those who do not want the experience, a keelboat monohull has physics on its side. But even yachts can capsize and turtle in extraordinary conditions, so design considerations are important, such events can overcome skill and experience, boats need to be appropriate for foreseeable conditions. A capsized kayak may be righted with a roll or eskimo rescue, in whitewater kayaking, capsizing occurs frequently and is accepted as an ordinary part of the sport. For sailing vessels, the ratio is a commonly published number used as a guideline for safe operation. However the only variables that go into capsize ratio are a beam and its displacement. A vessel may be designated as self-righting if it is designed to be able to then return to upright without intervention. Most small craft intended as lifeboats with rigid hulls designed since about the middle of the century are self-righting. In a storm, even large vessels may be rolled by being hit broadside by a wave or pitchpoled stem over stern in extreme waves. This is normally catastrophic for larger ships, and smaller yachts can be dismasted due to the drag as the boat is forced to roll over, among ship types, a roll-on-roll-off ship is more prone to capsizing as it has large open car decks near the waterline. If the watertight car-deck doors fail through damage or mismanagement, water entering the car-deck is subject to the surface effect. A ship that is holed may capsize, technically, this was not a capsize as her bottom was only partly exposed, rather this was a partial sinking. A vessel which capsizes without being holed may allow water to enter in places normally above the waterline, the ship may not then be able to right itself, stability and safety will be compromised even if the vessel is righted. In competitive yacht racing, a boat has certain special rights as it cannot maneuver

Meteorology
–
Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics, with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century, the 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data, Meteorological phenomena are observable weather events that are explained by the science of meteorology. Different spatial scales are used to describe and predict weather on local, regional, Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology compose the interdisciplinary field of hydrometeorology, the interactions between Earths atmosphere and its oceans are part of a coupled ocean-atmosphere system. Meteorology has application in diverse fields such as the military, energy production, transport, agriculture. The word meteorology is from Greek μετέωρος metéōros lofty, high and -λογία -logia -logy, varāhamihiras classical work Brihatsamhita, written about 500 AD, provides clear evidence that a deep knowledge of atmospheric processes existed even in those times. In 350 BC, Aristotle wrote Meteorology, Aristotle is considered the founder of meteorology. One of the most impressive achievements described in the Meteorology is the description of what is now known as the hydrologic cycle and they are all called swooping bolts because they swoop down upon the Earth. Lightning is sometimes smoky, and is then called smoldering lightning, sometimes it darts quickly along, at other times, it travels in crooked lines, and is called forked lightning. When it swoops down upon some object it is called swooping lightning, the Greek scientist Theophrastus compiled a book on weather forecasting, called the Book of Signs. The work of Theophrastus remained a dominant influence in the study of weather, in 25 AD, Pomponius Mela, a geographer for the Roman Empire, formalized the climatic zone system. According to Toufic Fahd, around the 9th century, Al-Dinawari wrote the Kitab al-Nabat, ptolemy wrote on the atmospheric refraction of light in the context of astronomical observations. St. Roger Bacon was the first to calculate the size of the rainbow. He stated that a rainbow summit can not appear higher than 42 degrees above the horizon, in the late 13th century and early 14th century, Kamāl al-Dīn al-Fārisī and Theodoric of Freiberg were the first to give the correct explanations for the primary rainbow phenomenon. Theoderic went further and also explained the secondary rainbow, in 1716, Edmund Halley suggested that aurorae are caused by magnetic effluvia moving along the Earths magnetic field lines. In 1441, King Sejongs son, Prince Munjong, invented the first standardized rain gauge and these were sent throughout the Joseon Dynasty of Korea as an official tool to assess land taxes based upon a farmers potential harvest. In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and was known as the first anemometer, in 1607, Galileo Galilei constructed a thermoscope

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

San Diego
–
San Diego is a major city in California, United States. It is in San Diego County, on the coast of the Pacific Ocean in Southern California, approximately 120 miles south of Los Angeles and immediately adjacent to the border with Mexico. With an estimated population of 1,394,928 as of July 1,2015, San Diego is the eighth-largest city in the United States and second-largest in California. It is part of the San Diego–Tijuana conurbation, the second-largest transborder agglomeration between the US and a country after Detroit–Windsor, with a population of 4,922,723 people. San Diego has been called the birthplace of California, historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain, the Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly independent Mexico, in 1850, California became part of the United States following the Mexican–American War and the admission of California to the union. The city is the seat of San Diego County and is the center of the region as well as the San Diego–Tijuana metropolitan area. San Diegos main economic engines are military and defense-related activities, tourism, international trade, the presence of the University of California, San Diego, with the affiliated UCSD Medical Center, has helped make the area a center of research in biotechnology. The original inhabitants of the region are now known as the San Dieguito, the area of San Diego has been inhabited by the Kumeyaay people. The first European to visit the region was Portuguese-born explorer Juan Rodríguez Cabrillo sailing under the flag of Castile, sailing his flagship San Salvador from Navidad, New Spain, Cabrillo claimed the bay for the Spanish Empire in 1542, and named the site San Miguel. In November 1602, Sebastián Vizcaíno was sent to map the California coast, in May 1769, Gaspar de Portolà established the Fort Presidio of San Diego on a hill near the San Diego River. It was the first settlement by Europeans in what is now the state of California, in July of the same year, Mission San Diego de Alcalá was founded by Franciscan friars under Junípero Serra. By 1797, the mission boasted the largest native population in Alta California, with over 1,400 neophytes living in, Mission San Diego was the southern anchor in California of the historic mission trail El Camino Real. Both the Presidio and the Mission are National Historic Landmarks, in 1821, Mexico won its independence from Spain, and San Diego became part of the Mexican territory of Alta California. In 1822, Mexico began attempting to extend its authority over the territory of Alta California. The fort on Presidio Hill was gradually abandoned, while the town of San Diego grew up on the land below Presidio Hill. The Mission was secularized by the Mexican government in 1833, the 432 residents of the town petitioned the governor to form a pueblo, and Juan María Osuna was elected the first alcalde, defeating Pío Pico in the vote

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

YouTube
–
YouTube is an American video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees—Chad Hurley, Steve Chen, and Jawed Karim—in February 2005, Google bought the site in November 2006 for US$1.65 billion, YouTube now operates as one of Googles subsidiaries. Unregistered users can watch videos on the site, while registered users are permitted to upload an unlimited number of videos. Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old, YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, Hurley had studied design at Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign. Karim could not easily find video clips of either event online, Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not. YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital between November 2005 and April 2006, YouTubes early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California. The domain name www. youtube. com was activated on February 14,2005, the first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo. The video was uploaded on April 23,2005, and can still be viewed on the site, YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005. Following a $3.5 million investment from Sequoia Capital in November, the site grew rapidly, and in July 2006 the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day. The site has 800 million unique users a month and it is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. The choice of the name www. youtube. com led to problems for a similarly named website, the sites owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to www. utubeonline. com, in October 2006, Google Inc. announced that it had acquired YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13,2006. In March 2010, YouTube began free streaming of certain content, according to YouTube, this was the first worldwide free online broadcast of a major sporting event. On March 31,2010, the YouTube website launched a new design, with the aim of simplifying the interface, Google product manager Shiva Rajaraman commented, We really felt like we needed to step back and remove the clutter. In May 2010, YouTube videos were watched more than two times per day. This increased to three billion in May 2011, and four billion in January 2012, in February 2017, one billion hours of YouTube was watched every day

Merchant vessel
–
A merchant vessel or trading vessel is a boat or ship that transports cargo or carries passengers for hire. This excludes pleasure craft that do not carry passengers for hire, most countries of the world operate fleets of merchant ships. However, due to the costs of operations, today these fleets are in many cases sailing under the flags of nations that specialize in providing manpower. Such flags are known as flags of convenience, currently, Liberia and Panama are particularly favoured. Ownership of the vessels can be by any country, however, the Greek-owned fleet is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world’s tonnage, during wars, merchant ships may be used as auxiliaries to the navies of their respective countries, and are called upon to deliver military personnel and materiel. The term commercial vessel is defined by the United States Coast Guard as any vessel engaged in trade or that carries passengers for hire. In English, Merchant Navy without further clarification is used to refer to the British Merchant Navy, general cargo ships include multi-purpose and project vessels and roll-on/roll-off cargo. A cargo ship or freighter is any sort of ship or vessel that carries cargo, goods, thousands of cargo carriers ply the worlds seas and oceans each year, they handle the bulk of international trade. Cargo ships are usually designed for the task, often being equipped with cranes and other mechanisms to load and unload. Dry cargo ships today are mainly bulk carriers and container ships, bulk carriers or bulkers are used for the transportation of homogeneous cargo such as coal, rubber, copra, tin, and wheat. Container ships are used for the carriage of miscellaneous goods, a bulk carrier is an ocean-going vessel used to transport bulk cargo items such as iron ore, bauxite, coal, cement, grain and similar cargo. Bulk carriers can be recognized by large box-like hatches on deck, the dimensions of bulk carriers are often determined by the ports and sea routes that they need to serve, and by the maximum width of the Panama Canal. Most lakes are too small to accommodate bulk carriers, but a large fleet of lake freighters has been plying the Great Lakes, container ships are cargo ships that carry all of their load in truck-size containers, in a technique called containerization. They form a common means of commercial freight transport. A tanker is a designed to transport liquids in bulk. Tankers can range in size from several hundred tons, designed to serve small harbours and coastal settlements, to several hundred thousand tons, gas Carriers such as LNG carriers as they are typically known, are a relatively rare tanker designed to carry liquefied natural gas. It has a deadweight of 565 thousand metric tons and length of about 458 meters, the use of such large ships is in fact very unprofitable, due to the inability to operate them at full cargo capacity, hence, the production of supertankers has currently ceased
