By 1900 nearly all Pacific islands were in control of Britain, France, United States, Germany, Japan, and Chile. Although the United States gained control of Guam and the Philippines from Spain in 1898, Japan controlled most of the western Pacific by 1914 and occupied many other islands during

7950-613: The islands in the world. There are about 25,000 islands in the Pacific Ocean. The islands entirely within the Pacific Ocean can be divided into three main groups known as Micronesia , Melanesia and Polynesia . Micronesia, which lies north of the equator and west of the International Date Line , includes the Mariana Islands in the northwest, the Caroline Islands in the center, the Marshall Islands to

8056-752: The islands of eastern Micronesia (including the Carolines , the Marshall Islands , and Kiribati ), mixing with earlier Austronesian migrations in the region. This remained the furthest extent of the Austronesian expansion into Polynesia until around 700 CE when there was another surge of island exploration. They reached the Cook Islands , Tahiti , and the Marquesas by 700 CE; Hawaiʻi by 900 CE; Rapa Nui by 1000 CE; and finally New Zealand by 1200 CE. Austronesians may have also reached as far as

8162-478: The limits of the Caribbean Sea as follows: Although Trinidad and Tobago and Barbados are on the same continental shelf, they are considered to be in the Atlantic Ocean rather than in the Caribbean Sea. The Caribbean Sea is an oceanic sea on the Caribbean Plate . The Caribbean Sea is separated from the ocean by several island arcs of various ages. The youngest stretches from the Lesser Antilles to

8268-777: The mainland river Orinoco and the Magdalena River . Deposits on the bottom of the Caribbean Sea and the Gulf of Mexico have a thickness of about 1 km (0.62 mi). Upper sedimentary layers relate to the period from the Mesozoic to the Cenozoic (250 million years ago) and the lower layers from the Paleozoic to the Mesozoic . The Caribbean seafloor is divided into five basins separated from each other by underwater ridges and mountain ranges. Atlantic Ocean water enters

8374-403: The most diverse marine habitats in the world, but they are fragile ecosystems. When tropical waters become unusually warm for extended periods of time, microscopic plants called zooxanthellae , which are symbiotic partners living within the coral polyp tissues, die off. These plants provide food for the corals and give them their color. The result of the death and dispersal of these tiny plants

8480-523: The north and its convergence with the Euramerica basin decreased in size. The next stage of the Caribbean Sea's formation began in the Triassic . Powerful rifting led to the formation of narrow troughs, stretching from modern Newfoundland to the Gulf of Mexico's west coast, forming siliciclastic sedimentary rocks . In the early Jurassic due to powerful marine transgression , water broke into

8586-601: The north to New Zealand in the south, also encompasses Tuvalu , Tokelau , Samoa , Tonga and the Kermadec Islands to the west, the Cook Islands , Society Islands and Austral Islands in the center, and the Marquesas Islands , Tuamotu , Mangareva Islands , and Easter Island to the east. Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs and uplifted coral platforms. Continental islands lie outside

8692-619: The northern Philippines , but also earlier groups associated with Austroasiatic-speakers , resulting in the modern peoples of Island Southeast Asia and Oceania. A later seaborne migration is the Neolithic Austronesian expansion of the Austronesian peoples . Austronesians originated from the island of Taiwan c.  3000 –1500 BCE. They are associated with distinctive maritime sailing technologies (notably outrigger boats , catamarans , lashed-lug boats, and

8798-551: The northern Atlantic as the Guiana Current and part of the North Equatorial Current enter the sea on the east. On the western side of the sea, the trade winds influence a northerly current which causes an upwelling and a rich fishery near Yucatán . The Caribbean is home to about 9% of the world's coral reefs , covering about 50,000 km (19,000 sq mi), most of which are located off

8904-565: The northern part of the sea Cuba , Hispaniola , Jamaica and Puerto Rico lie on an older island arc. The geological age of the Caribbean Sea is estimated to be between 160 and 180 million years and was formed by a horizontal fracture that split the supercontinent called Pangea in the Mesozoic Era . It is assumed the proto-caribbean basin existed in the Devonian period and in the early Carboniferous movement of Gondwana to

9010-485: The northern tip of Yucatán Tropical cyclones are a threat to the nations that rim the Caribbean Sea. While landfalls are infrequent, the resulting loss of life and property damage makes them a significant hazard to life in the Caribbean. Tropical cyclones that impact the Caribbean often develop off the West coast of Africa and make their way west across the Atlantic Ocean toward the Caribbean, while other storms develop in

9116-575: The northwestern Pacific and the eastern Pacific. Pacific hurricanes form south of Mexico, sometimes striking the western Mexican coast and occasionally the Southwestern United States between June and October, while typhoons forming in the northwestern Pacific moving into southeast and east Asia from May to December. Tropical cyclones also form in the South Pacific basin , where they occasionally impact island nations. In

9222-439: The number of green turtles has declined from 91 million to 300,000 and hawksbill turtles from 11 million to less than 30,000 by 2006. All 170 species of amphibians that live in the region are endemic. The habitats of almost all members of the toad family, poison dart frogs , tree frogs and leptodactylidae (a type of frog) are limited to only one island. The Golden coqui is in serious threat of extinction. In

9328-451: The ocean was encountered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and reached a new ocean. He named it Mar del Sur ("Sea of the South" or "South Sea" ) because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. In 1520, navigator Ferdinand Magellan and his crew were the first to cross

9434-562: The ocean's surface. One of the most dramatic is the Great Barrier Reef off northeastern Australia with chains of reef patches. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba (formerly Ocean Island) and Makatea in the Tuamotu group of French Polynesia . The volume of the Pacific Ocean, representing about 50.1 percent of

9540-549: The present area of the Gulf of Mexico creating a vast shallow pool. Deep basins emerged in the Caribbean during the Middle Jurassic rifting . The emergence of these basins marked the beginning of the Atlantic Ocean and contributed to the destruction of Pangaea at the end of the late Jurassic . During the Cretaceous the Caribbean acquired a shape close to today. In the early Paleogene due to marine regression

9646-581: The quest for Terra Australis ("the [great] Southern Land"), Spanish explorations in the 17th century, such as the expedition led by the Portuguese navigator Pedro Fernandes de Queirós , arrived at the Pitcairn and Vanuatu archipelagos, and sailed the Torres Strait between Australia and New Guinea, named after navigator Luís Vaz de Torres . Dutch explorers, sailing around southern Africa, also engaged in exploration and trade; Willem Janszoon , made

9752-773: The reefs could severely damage the region's economy. A Protocol of the Convention for the Protection and Development of the Marine Environment of the Wider Caribbean Region came in effect in 1986 to protect the various endangered marine life of the Caribbean through forbidding human activities that would advance the continued destruction of such marine life in various areas. Currently this protocol has been ratified by 15 countries. Also, several charitable organisations have been formed to preserve

9858-558: The region have representatives of both the Indian and Pacific oceans which were caught in the Caribbean before the emergence of the Isthmus of Panama four million years ago. In the Caribbean Sea there are around 1,000 documented species of fish, including sharks ( bull shark , tiger shark , silky shark and Caribbean reef shark ), flying fish , giant oceanic manta ray , angel fish , spotfin butterflyfish , parrotfish , Atlantic Goliath grouper , tarpon and moray eels . Throughout

9964-493: The region. The tropical rainforest climates include lowland areas near the Caribbean Sea from Costa Rica north to Belize , as well as the Dominican Republic and Puerto Rico , while the more seasonal dry tropical savanna climates are found in Cuba , northern Venezuela , and southern Yucatán, Mexico . Arid climates are found along the extreme northern coast of Venezuela out to the islands including Aruba and Curaçao , as well as

10070-533: The same isthmus). The Caribbean Sea had been unknown to the populations of Eurasia until after 1492 when Christopher Columbus sailed into Caribbean waters to find a sea route to Asia. At that time, the Americas were generally unknown to most Europeans, although they had been visited in the 10th century by the Vikings . Following Columbus's discovery of the islands, the area was quickly colonized by several Western cultures (initially Spain , then later England ,

10176-451: The seawater is about 3.6%, and its density is 1,023.5–1,024.0 kg/m (63.90–63.93 lb/cu ft). The surface water color is blue-green to green . The Caribbean's depth in its wider basins and deep-water temperatures are similar to those of the Atlantic. Atlantic deep water is thought to spill into the Caribbean and contribute to the general deep water of its sea. The surface water (30 m; 100 ft) acts as an extension of

10282-505: The settlement of Buka by 32,000 B.P. and Manus by 25,000 B.P. Journeys of 180 kilometres (110 mi) and 230 kilometres (140 mi) are involved, respectively. The descendants of these migrations today are the Negritos , Melanesians , and Indigenous Australians . Their populations in maritime Southeast Asia , coastal New Guinea , and Island Melanesia later intermarried with the incoming Austronesian settlers from Taiwan and

10388-540: The sewage from the Central American and Caribbean Island countries is properly treated before being released into the sea. The region has been famous for its rum production - the drink is first mentioned in records from Barbados in around 1650, although it was likely to have been produced beforehand across the other islands. The Caribbean region supports a large tourism industry. The Caribbean Tourism Organization calculates that about 12 million people

10494-818: The south from the Venezuelan coastline to the Colombian coastline , and Central America and the Yucatán Peninsula to the west from Panama to Mexico . The geopolitical region centered around the Caribbean Sea, including the numerous islands of the West Indies and adjacent coastal areas in the mainland of the Americas , is known as the Caribbean . The Caribbean Sea is one of the largest seas on Earth and has an area of about 2,754,000 km (1,063,000 sq mi). The sea's deepest point

10600-504: The southeast of Hawaii is computed, and if the region is more than 0.5 °C (0.9 °F) above or below normal for that period, then an El Niño or La Niña is considered in progress. In the tropical western Pacific, the monsoon and the related wet season during the summer months contrast with dry winds in the winter which blow over the ocean from the Asian landmass. Worldwide, tropical cyclone activity peaks in late summer, when

10706-410: The surface do not exceed 3 °C (5.4 °F). Over the past 50 years, the Caribbean has gone through three stages: cooling until 1974, a cold phase with peaks during 1974–1976 and 1984–1986, and finally a warming phase with an increase in temperature of 0.6 °C (1.1 °F) per year. Virtually all temperature extremes were associated with the phenomena of El Niño and La Niña . The salinity of

10812-804: The tropics and Antarctica, which records the coldest temperature readings on the planet. In the Southern hemisphere, because of the stormy and cloudy conditions associated with extratropical cyclones riding the jet stream, it is usual to refer to the Westerlies as the Roaring Forties, Furious Fifties and Shrieking Sixties according to the varying degrees of latitude. The ocean was first mapped by Abraham Ortelius ; he called it Maris Pacifici following Ferdinand Magellan 's description of it as "a pacific sea" during his circumnavigation from 1519 to 1522. To Magellan, it seemed much more calm (pacific) than

10918-586: The west, and Drake Passage and the Strait of Magellan link the Pacific with the Atlantic Ocean on the east. To the north, the Bering Strait connects the Pacific with the Arctic Ocean . As the Pacific straddles the 180th meridian , the West Pacific (or western Pacific , near Asia) is in the Eastern Hemisphere , while the East Pacific (or eastern Pacific , near the Americas) is in

11024-597: The width of the Pacific with precision for the first time in history. 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 European powers, and later Japan and

11130-434: The world's oceanic water, has been estimated at some 714 million cubic kilometers (171 million cubic miles). Surface water temperatures in the Pacific can vary from −1.4 °C (29.5 °F), the freezing point of seawater, in the poleward areas to about 30 °C (86 °F) near the equator. Salinity also varies latitudinally, reaching a maximum of 37 parts per thousand in the southeastern area. The water near

11236-583: Was the first to show the Americas separating two distinct oceans. Later, the Diogo Ribeiro map of 1529 was the first to show the Pacific at about its proper size. (Inhabited dependent territories are denoted by the asterisk (*), with names of the corresponding sovereign states in round brackets. Associated states in the Realm of New Zealand are denoted by the hash sign (#).) Territories with no permanent civilian population. The Pacific Ocean has most of
