Antarctica Introduction
Background: Speculation over the existence of a "southern land" was not confirmed until the early 1820s when British and American commercial operators and British and Russian national expeditions began exploring the Peninsula region and areas south of the Antarctic Circle. Not until 1838 was it established that Antarctica was indeed a continent and not just a group of islands. Various "firsts" were achieved in the early 20th century, including: 1902, first balloon flight (by British explorer Robert Falcon SCOTT); 1912, first to the South Pole (five Norwegian explorers under Roald AMUNDSEN); 1928, first fixed-wing aircraft flight (by Australian adventurer/explorer Sir Hubert WILKINS); 1929, first flight over the South Pole (by Americans Richard BYRD and Bernt BALCHEN); and 1935, first transantarctic flight (American Lincoln ELLSWORTH). Following World War II, there was an upsurge in scientific research on the continent. A number of countries have set up year-round research stations on Antarctica. Seven have made territorial claims, but no other country recognizes these claims. In order to form a legal framework for the activities of nations on the continent, an Antarctic Treaty was negotiated that neither denies nor gives recognition to existing territorial claims; signed in 1959, it entered into force in 1961.
Antarctica Geography
Location: continent mostly south of the Antarctic Circle
Geographic coordinates: 90 00 S, 0 00 E
Map references: Antarctic Region
Area: total: 14 million sq km
land: 14 million sq km (280,000 sq km ice-free, 13.72 million sq km ice-covered) (est.)
note: fifth-largest continent, following Asia, Africa, North America, and South America, but larger than Australia and the subcontinent of Europe
Area - comparative: slightly less than 1.5 times the size of the US
Land boundaries: 0 km
note: see entry on International disputes
Coastline: 17,968 km
Maritime claims: none; twenty 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 5,140 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 −2,540 m
highest point: Vinson Massif 5,140 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 sea water
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%
permanent pastures: 0%
forests and woodland: 0%
other: 100% (ice 98%, barren rock 2%)
Irrigated land: 0 sq km (1993)
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
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
Antarctica People
Population: no indigenous inhabitants, but there are seasonally staffed research stations
note: approximately 29 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) and year-round research on the continent and in its surrounding oceans; the population of persons doing and supporting science on the continent and its nearby islands south of 60 degrees south latitude (the region covered by the Antarctic Treaty) varies from approximately 4,000 in summer to 1,000 in winter; in addition, approximately 1,000 personnel including ship's crew and scientists doing onboard research are present in the waters of the treaty region; Summer (January) population - 3,687 total; Argentina 302, Australia 201, Belgium 13, Brazil 80, Bulgaria 16, Chile 352, China 70, Finland 11, France 100, Germany 51, India 60, Italy 106, Japan 136, South Korea 14, Netherlands 10, NZ 60, Norway 40, Peru 28, Poland 70, Russia 254, South Africa 80, Spain 43, Sweden 20, UK 192, US 1,378 (1998–99); Winter (July) population - 964 total; Argentina 165, Australia 75, Brazil 12, Chile 129, China 33, France 33, Germany 9, India 25, Japan 40, South Korea 14, NZ 10, Poland 20, Russia 102, South Africa 10, UK 39, US 248 (1998–99); year-round stations - 42 total; Argentina 6, Australia 4, Brazil 1, Chile 4, China 2, Finland 1, France 1, Germany 1, India 1, Italy 1, Japan 1, South Korea 1, NZ 1, Norway 1, Poland 1, Russia 6, South Africa 1, Spain 1, Ukraine 1, UK 2, US 3, Uruguay 1 (1998–99); Summer-only stations - 32 total; Argentina 3, Australia 4, Bulgaria 1, Chile 7, Germany 1, India 1, Japan 3, NZ 1, Peru 1, Russia 3, Sweden 2, UK 5 (1998–99); in addition, during the austral summer some nations have numerous occupied locations such as tent camps, summer-long temporary facilities, and mobile traverses in support of research (July 2001 est.)
