The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern (or Antarctic) Ocean or, depending on definition, the southern Pacific , Atlantic , and Indian Oceans .
Antarctic krill is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, crabeater seals, squid, icefish, penguins, albatrosses and many other birds.
Antarctic melt stream. Antarctica is a desert, receiving very little annual precipitation. [1] However meltwater from the continent's ice features produce a number of rivers and streams. A list of these can be found at List of rivers of Antarctica
Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km 2 (5,500,000 sq mi).
This is a list of Antarctic and sub-Antarctic islands. Antarctic islands are, in the strict sense, the islands around mainland Antarctica, situated on the Antarctic Plate, and south of the Antarctic Convergence. According to the terms of the Antarctic Treaty, claims to sovereignty over lands south of 60° S are not asserted. [1]
Its west coast from the tip of the Antarctic Peninsula south to 68° S, which has a maritime Antarctic climate, is the mildest part of the Antarctic Peninsula. Within this part of the Antarctic Peninsula, temperatures exceed 0 °C (32 °F) for 3 or 4 months during the summer, and rarely fall below −10 °C (14 °F) during the winter.
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
