Antarctica

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 Antarctic Peninsula region and other areas south of the Antarctic Circle. Not until 1840 was it established that Antarctica was indeed a continent and not just a group of islands. Several exploration "firsts" were achieved in the early 20th century. 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.
Location: Location: Continent mostly south of the Antarctic Circle 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.) Area - comparative: Slightly less than 1.5 times the size of the US Coastline: 17,968 km
Climate and Terrain: 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

People: No indigenous inhabitants, but there are seasonally staffed research stations
Government: Government type: Antarctic Treaty Summary - the Antarctic Treaty, signed on 1 December 1959 and entered into force on 23 June 1961, establishes the legal framework for the management of Antarctica.
Economy overview: Economy - overview: Fishing off the coast and tourism, both based abroad, account for the limited economic activity. Antarctic fisheries in 2000-01 (1 July-30 June) reported landing 112,934 metric tons. Unregulated fishing, particularly of tooth fish, is a serious problem. Allegedly illegal fishing in Antarctic waters in 1998 resulted in the seizure (by France and Australia) of at least eight fishing ships. The Convention on the Conservation of Antarctic Marine Living Resources determines the recommended catch limits for marine species. A total of 12,248 tourists visited in the 2000-01 Antarctic summer, down from the 14,762 who visited the previous year. Nearly all of them were passengers on 21 commercial (nongovernmental) ships and several yachts that made trips during the summer. Most tourist trips lasted approximately two weeks.
Statistics: Airports: 30 Airports - with unpaved runways: Total: 19. Heliports: 27 stations have helicopter-landing facilities.
