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. Of the three oceans that extend northward from the Antarctic continent, the Pacific is by far the largest, occupying about a third of the surface of the globe. [64], The climate patterns of the Northern and Southern Hemispheres generally mirror each other. It may be further subdivided by the equator into northern (North Pacific) and southern (South Pacific) portions. The Pacific Ocean is the largest and deepest ocean on Earth. The portion of the Pacific near Antarctica sometimes is considered to be part of the Southern Ocean.

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. Calcareous globigerina ooze occurs in the shallower parts of the South Pacific, the dissolving power of the seawater at great depths being sufficient to dissolve calcareous material to such an extent that these oozes are not generally found at depths in excess of about 15,000 feet (4,600 metres). Of the rivers that drain into the Pacific, those of China and Southeast Asia are of the greatest importance; the basins of those rivers support more than one-fourth of the world’s population.

The ocean is explorable, similar to Grand Theft Auto: San Andreas, though with much more detail. The Pacific basin may conveniently be divided into three major physiographic regions: the eastern, western, and central Pacific regions. The dissimilarity continues northeastward along the western edge of the Andes Cordillera along South America to Mexico, returning then to the islands off California. [86], Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. The large series of volcanoes (some active) encircling the Pacific Ocean are referred to as being part of the Ring of Fire, and notorious for frequent earthquakes and volcanic eruptions. Although the United States gained control of Guam and the Philippines from Spain in 1898,[35] Japan controlled most of the western Pacific by 1914 and occupied many other islands during the Pacific War; however, by the end of that war, Japan was defeated and the U.S. Pacific Fleet was the virtual master of the ocean. [68] The Pacific hosts the two most active tropical cyclone basins, which are the northwestern Pacific and the eastern Pacific.

However, it is relatively wide in Australia and Asia.The East Pacific is a mid-ocean ridge extending in the longitudinal direction, some 8,700 km from the Gulf of California to a located about 3,600 km west of the southern tip of South America point, and rises with an average height about 2,130 m above the ocean floor. Only the Antarctic and Australian coasts have no nearby subduction zones. In the eastern Pacific the Cocos Ridge extends southwestward from the Central American isthmus to the Galapagos Islands. Significant contributions to oceanographic knowledge were made by the voyages of HMS Beagle in the 1830s, with Charles Darwin aboard;[29] HMS Challenger during the 1870s;[30] the USS Tuscarora (1873–76);[31] and the German Gazelle (1874–76). The northernmost chain of oceanic islands is associated with the Hawaiian Ridge. [28] One of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. “Pacific-ing Asian Pacific American History,”, This page was last edited on 16 January 2021, at 04:11. They cover large areas of the ocean floor in the Pacific. The ocean's current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favorable winds on reaching the ocean. When there is more … Its area, excluding adjacent seas, encompasses about 63.8 million square miles (165.25 million square km). Pacific Ocean Facts: What is the Great Barrier Reef? [1] The Pacific Ocean encompasses approximately one-third of the Earth's surface, having an area of 165,200,000 km2 (63,800,000 sq mi)— larger than Earth's entire landmass combined, 150,000,000 km2 (58,000,000 sq mi).

The largest and the most geologically stable of the structural provinces of the Earth’s crust, it is characterized by expansive areas of low relief, lying at a general depth of about 15,000 feet (4,600 metres) below the surface. The seaward boundary of the western Pacific region is marked by a broken line of oceanic trenches, extending from the Aleutian Trench in the north through the Kuril and Japan trenches and southward to the Tonga and Kermadec trenches, terminating close to the northeast of North Island, New Zealand. Updates? Tropical cyclones also form in the South Pacific basin, where they occasionally impact island nations. Red or brown radiolarian ooze is found along the zone of the Pacific North Equatorial Current, east of longitude 170° W, and on the floors of some deep Indonesian basins. Davidson, James Wightman. Its greatest longitudinal extent measures some 12,000 miles (19,300 km) along latitude 5° N, between the coasts of Colombia in South America and the Malay Peninsula in Asia. The numerous oceanic islands of the Pacific are unevenly distributed. [23] For the remainder of the 16th century, Spanish influence was paramount, with ships sailing from Mexico and Peru across the Pacific Ocean to the Philippines via Guam, and establishing the Spanish East Indies. At 165,250,000 square kilometers (63,800,000 square miles) in the area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, making it larger than all of Earth's land area combined (148,000,000 square kilometers). The region’s physiography is dominated by a group of large continental islands, however, including New Guinea. Of great geologic interest are the seamounts (submerged volcanoes), guyots (flat-topped seamounts), and oceanic islands of the Pacific. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone. Pacific Ocean Shipping & Maritime Group provides reliable, safe and efficient marine services to the global maritime and oil and gas industry.

The trade winds in the southern and eastern Pacific are remarkably steady while conditions in the North Pacific are far more varied with, for example, cold winter temperatures on the east coast of Russia contrasting with the milder weather off British Columbia during the winter months due to the preferred flow of ocean currents. The Pacific Ocean bounds Asia and Australia to the West, the Americas to the East, the Arctic to the North and Antarctica to the South. It is quite narrow throughout the South and North America. Significant oceanic trenches in this region are the Middle America Trench in the North Pacific and the Peru-Chile Trench in the South Pacific. [18] Sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands,[19] the Aru Islands,[20] and Papua New Guinea.

[16] Magellan stopped at one uninhabited Pacific island before stopping at Guam in March 1521. It is of oceanographic significance that the great rivers of eastern Asia—including the Amur, the Huang He (Yellow River), the Yangtze, the Xi and Pearl (Zhu), and the Mekong—enter the Pacific indirectly by way of the marginal seas. Module:Location map/data/Pacific Ocean is a location map definition used to overlay markers and labels on an equirectangular projection map of Pacific Ocean. From north to south they include the Bering Sea, the Sea of Okhotsk, the Sea of Japan (East Sea), the Yellow Sea, the East China Sea, and the South China Sea.

Ocean between Asia and Australia in the west, the Americas in the east and Antarctica or the Southern Ocean in the south. A petrologic boundary, it separates the deeper, mafic igneous rock of the Central Pacific Basin from the partially submerged continental areas of felsic igneous rock on its margins. It has double the area and more than double the water volume of the Atlantic Ocean—the next largest division of the hydrosphere—and its area more than exceeds that of the whole land surface of the globe. Apart from the narrow coastal zone of the eastern region and the broad continental seas of the western region, the Pacific is floored with pelagic (oceanic) material derived from the remains of marine plants and animals that once inhabited the waters lying above. The island clusters of the western Pacific form the boundaries of the several wide and deep continental seas of the region. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality. The nodules so formed contain manganese, iron, nickel, copper, cobalt, and traces of other metals such as platinum. Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. By contrast, the Atlantic Ocean is increasing in size. Among the many different forms of land-derived muds (formed by the erosive action of rivers, tides, and currents) that floor the continental shelves and slopes of the Pacific, the yellow mud of the Yellow Sea is of particular interest. ), guyots ( flat-topped seamounts ), guyots ( flat-topped seamounts ) New.
