Airports - with unpaved runways | total:
19 over 3,047 m: 6 2,438 to 3,047 m: 3 1,524 to 2,437 m: 1 914 to 1,523 m: 4 under 914 m: 5 (2000 est.) |
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 |
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. |
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 |
Coastline | 17,968 km |
Country name | conventional long form:
none conventional short form: Antarctica |
Disputes - international | Antarctic Treaty freezes claims (see Antarctic Treaty Summary in Government type entry); sections (some overlapping) claimed by Argentina, Australia, Chile, France, New Zealand, Norway, and UK; the US and most other nations do not recognize the territorial claims of other nations and have made no claims themselves (the US and Russia reserve the right to do so); no claims have been made in the sector between 90 degrees west and 150 degrees west |
Economy - overview | Fishing off the coast and tourism, both based abroad, account for the limited economic activity. Antarctic fisheries in 1998-99 (1 July-30 June) reported landing 119,898 metric tons. Unregulated fishing landed five to six times more than the regulated fishery, and allegedly illegal fishing in antarctic waters in 1998 resulted in the seizure (by France and Australia) of at least eight fishing ships. Companies interested in commercial fishing activities in Antarctica have put forward proposals. The Convention on the Conservation of Antarctic Marine Living Resources determines the recommended catch limits for marine species. A total of 13,193 tourists visited in the 1999-2000 summer, up from the 10,013 who visited the previous year. Nearly all of them were passengers on 24 commercial (nongovernmental) ships and several yachts that made 143 trips during the summer. Most tourist trips lasted approximately two weeks. |
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 |
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 |
Geographic coordinates | 90 00 S, 0 00 E |
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 |
Heliports | 27 stations have helicopter landing facilities (helipads) (2001 est.) |

Legal system | Antarctica is administered through meetings of the consultative member nations. Decisions from these meetings are carried out by these member nations (within their areas) in accordance with their own national laws. US law, including certain criminal offenses by or against US nationals, such as murder, may apply extra-territorially. Some US laws directly apply to Antarctica. For example, the Antarctic Conservation Act, 16 U.S.C. section 2401 et seq., provides civil and criminal penalties for the following activities, unless authorized by regulation of statute: the taking of native mammals or birds; the introduction of nonindigenous plants and animals; entry into specially protected areas; the discharge or disposal of pollutants; and the importation into the US of certain items from Antarctica. Violation of the Antarctic Conservation Act carries penalties of up to $10,000 in fines and one year in prison. The National Science Foundation and Department of Justice share enforcement responsibilities. Public Law 95-541, the US Antarctic Conservation Act of 1978, as amended in 1996, requires expeditions from the US to Antarctica to notify, in advance, the Office of Oceans and Polar Affairs, Room 5801, Department of State, Washington, DC 20520, which reports such plans to other nations as required by the Antarctic Treaty.
