It is the foremost example of habitat that is critical to the survival of many species, each dependent on the health of a complex food web, based in part on krill. Now both import…  Two species of salps are common in Antarctic waters, Salpa thompsoni and Ihlea racovitzai.  In winter the ocean freezes outward to 65 degrees south latitude in the Pacific sector and 55 degrees south latitude in the Atlantic sector, lowering surface temperatures well below 0 degrees Celsius. These young kittens and cats are available for adoption through our foster program. The Steller’s sea cow is listed as extinct and no on… In November 1774, Cook started from New Zealand and crossed the South Pacific without sighting land between 53° and 57° S to Tierra del Fuego; then, passing Cape Horn on 29 December, he rediscovered Roché Island renaming it Isle of Georgia, and discovered the South Sandwich Islands (named Sandwich Land by him), the only ice-clad land he had seen, before crossing the South Atlantic to the Cape of Good Hope between 55° and 60°. Fur seals are mainly found on the sub-antarctic islands. Antarctic sea life includes penguins, blue whales, orcas, colossal squids and fur seals. , Other sources, such as the National Geographic Society, show the Atlantic, Pacific, and Indian oceans as extending to Antarctica on its maps, although articles on the National Geographic web site have begun to reference the Southern Ocean.. Placer deposits, accumulation of valuable minerals such as gold, formed by gravity separation during sedimentary processes are also expected to exist in the Southern Ocean. © 1986 Panda Symbol WWF – World Wide Fund For Nature (formerly World Wildlife Fund), Protecting Antarctica and the Southern Oceans, Protecting against climate change in Antarctica, Marine protected areas for Antarctica and the Southern Ocean, Climate Witness: David Ainley, Antarctica, the impacts of climate change on Antarctica and in the Southern Ocean are understood and effective, a moratorium on mineral exploitation in the region remains in place under the. Fin Whale. Currently, these little cuties reside with … The other four species can live on the sea ice.  Emperor penguins have four overlapping layers of feathers, keeping them warm. , The benthic communities of the seafloor are diverse and dense, with up to 155,000 animals found in 1 square metre (10.8 sq ft). The Southern Ocean is the coldest and windiest ocean on Earth. Emperor Penguin. WWF is leading the fight to protect Antarctica and the Southern Ocean. The expedition was planned to last for eight months but was unexpectedly terminated after only two months. This difference in practice is markedly seen for the Pacific Ocean in the adjacent figure. Other cats and kittens are available for adoption from the Southern Ocean County Animal Facility located at 360 Haywood Rd., Manahawkin, NJ 08050. The gyres are formed by interactions between the Antarctic Circumpolar Current and the Antarctic Continental Shelf. Crabeater seals (Lobodon carcinophagus) and Weddell seals (Leptonychotes weddellii) form breeding colonies, whereas leopard seals (Hydrurga leptonyx) and Ross seals (Ommatophoca rossii) live solitary lives. As the seafloor environment is very similar all around the Antarctic, hundreds of species can be found all the way around the mainland, which is a uniquely wide distribution for such a large community.  Explorer was the first cruise ship used specifically to sail the icy waters of the Antarctic Ocean and the first to sink there when she struck an unidentified submerged object on 23 November 2007, reported to be ice, which caused a 10 by 4 inches (25 by 10 cm) gash in the hull. Some ocean animals spend most of their life in the waters near the land. Based on the original 1928 IHO delineation of the Southern Ocean (and the 1937 delineation if the Great Australian Bight is considered integral), Australian ports and harbors between Cape Leeuwin and Cape Otway on the Australian mainland and along the west coast of Tasmania would also be identified as ports and harbors existing in the Southern Ocean. In clockwise order these include (with sector): A number of these such as the 2002 Russian-proposed "Cosmonauts Sea", "Cooperation Sea", and "Somov (mid-1950s Russian polar explorer) Sea" are not included in the 1953 IHO document which remains currently in force, because they received their names largely originated from 1962 onward. More surprising are small forms of life such as mudworms, sea cucumbers and free-swimming snails found in both polar oceans. that the Weddell Sea and the Ross Sea are not connected. "Warming of the Southern Ocean since the 1950s": Descriptive Regional Oceanography, P. Tchernia, Pergamon Press, 1980. Map of The World in 1922 by the National Geographic Society showing the Antarctic (Southern) Ocean. , There are relatively few fish species in few families in the Southern Ocean. Adelie Penguin.

The limit then followed the west coast of Tasmania southwards to the South East Cape and then went eastwards to Broughton Island, New Zealand, before returning to Cape Horn.. International agreements came into force in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 1998–99 season landed five to six times more Patagonian toothfish than the regulated fishery. A far cry from the land of singing crustaceans and forgetful (yet totally good-natured!) Our mission is to prevent cruelty to animals, to promote kindness to animals, and to conduct projects for the benefit and welfare of animals in Ocean County, and to promote shelter pet adoptions through publicity and public relations. ):4, Instead, in the IHO 1953 publication, the Atlantic, Indian and Pacific Oceans were extended southward, the Indian and Pacific Oceans (which had not previously touched pre 1953, as per the first and second editions) now abutted at the meridian of South East Cape, and the southern limits of the Great Australian Bight and the Tasman Sea were moved northwards.. Pacific Ocean Animals. , A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. Others live most of their life in the deeper open sea. The ocean, the original home of earth’s animal life, has creatures of every size and type.  The Family Magazine in 1835 divided the "Great Southern Ocean" into the "Southern Ocean" and the "Antarctick [sic] Ocean" along the Antarctic Circle, with the northern limit of the Southern Ocean being lines joining Cape Horn, the Cape of Good Hope, Van Diemen's Land and the south of New Zealand. , The icebergs that form each year around in the Southern Ocean hold enough fresh water to meet the needs of every person on Earth for several months. , The four species that inhabit sea ice are thought to make up 50% of the total biomass of the world's seals. At approximately 20.3 million square kilometers (7.8 million square miles) and about twice the size of the U.S.A., the new ocean is the world's fourth-largest (following the Pacific, Atlantic, and Indian, but larger than the Arctic Ocean). the CIA World Fact Book) which already adopted the principle that seas are contained within oceans. Another four species live on the subantarctic islands.
