Land use: arable land: 0% permanent crops: 0% other: 100% (ice 98%, barren rock 2%) (1998 est.)
Irrigated land: 0 sq km (1998 est.)
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
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
People Antarctica
Population: no indigenous inhabitants, but there are seasonally staffed research stations note: approximately 27 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 2002 est.)
