Geography Of Antarctica

Location	continent mostly south of the Antarctic Circle
Geographic coordinates	90 00 S, 0 00 E
Map references	antarctic
Area	total: 14 million sq km note: fifth-largest continent, following Asia, Africa, North America, and South America, but larger than Australia and the subcontinent of Europe land: 14 million sq km (280,000 sq km ice-free, 13.72 million sq km ice-covered) (est.)
Area comparative	slightly less than 1.5 times the size of the US
Land boundaries	0 km note: see entry on Disputes - international
Coastline	17,968 km
Maritime claims	Australia, Chile, and Argentina claim Exclusive Economic Zone (EEZ) rights or similar over 200 nm extensions seaward from their continental claims, but like the claims themselves, these zones are not accepted by other countries; 20 of 27 Antarctic consultative nations have made no claims to Antarctic territory (although Russia and the US have reserved the right to do so) and do not recognize the claims of the other nations; also see the Disputes - international entry
Climate	severe low temperatures vary with latitude, elevation, and distance from the ocean; East Antarctica is colder than West Antarctica because of its higher elevation; Antarctic Peninsula has the most moderate climate; higher temperatures occur in January along the coast and average slightly below freezing
Terrain	about 98% thick continental ice sheet and 2% barren rock, with average elevations between 2,000 and 4,000 meters; mountain ranges up to nearly 5,000 meters; ice-free coastal areas include parts of southern Victoria Land, Wilkes Land, the Antarctic Peninsula area, and parts of Ross Island on McMurdo Sound; glaciers form ice shelves along about half of the coastline, and floating ice shelves constitute 11% of the area of the continent
Elevation extremes	lowest point: Bentley Subglacial Trench -2,555 m highest point: Vinson Massif 4,897 m note: the lowest known land point in Antarctica is hidden in the Bentley Subglacial Trench; at its surface is the deepest ice yet discovered and the world's lowest elevation not under seawater
Natural resources	iron ore, chromium, copper, gold, nickel, platinum and other minerals, and coal and hydrocarbons have been found in small uncommercial quantities; none presently exploited; krill, finfish, and crab have been taken by commercial fisheries
Land use	arable land: 0% permanent crops: 0% other: 100% (ice 98%, barren rock 2%) (2001)
Irrigated land	0 sq km
Natural hazards	katabatic (gravity-driven) winds blow coastward from the high interior; frequent blizzards form near the foot of the plateau; cyclonic storms form over the ocean and move clockwise along the coast; volcanism on Deception Island and isolated areas of West Antarctica; other seismic activity rare and weak; large icebergs may calve from ice shelf
Environment - current issues	in 1998, NASA satellite data showed that the antarctic ozone hole was the largest on record, covering 27 million square kilometers; researchers in 1997 found that increased ultraviolet light coming through the hole damages the DNA of icefish, an antarctic fish lacking hemoglobin; ozone depletion earlier was shown to harm one-celled antarctic marine plants; in 2002, significant areas of ice shelves disintegrated in response to regional warming
Environment - international agreements
Geography note	the coldest, windiest, highest (on average), and driest continent; during summer, more solar radiation reaches the surface at the South Pole than is received at the Equator in an equivalent period; mostly uninhabitable
