Antarctica :: Antarctica

- Introduction :: 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 merely a group of islands or an area of ocean. Several exploration "firsts" were achieved in the early 20th century, but generally the area saw little human activity. Following World War II, however, the continent experienced an upsurge in scientific research. A number of countries have set up a range of year-round and seasonal stations, camps, and refuges to support scientific research in Antarctica. Seven have made territorial claims, but not all countries recognize 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.
- Geography :: Antarctica
- 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

  country comparison to the world: 2
  Area - comparative:
  slightly less than 1.5 times the size of the US
  Land boundaries:
  0

  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; 22 of 29 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:
  the coldest, windiest, and driest continent on Earth; 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; summers characterized by continuous daylight, while winters bring continous darkness; persistent high pressure over the interior brings dry, subsiding air that results in very little cloud cover
  Terrain:
  about 98% thick continental ice sheet and 2% barren rock, with average elevations between 2,000 and 4,000 m; mountain ranges up to nearly 5,000 m; 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:
  mean elevation: 2,300 m
  elevation extremes: -2,540 m lowest point: Bentley Subglacial Trench
  4892 highest point: Vinson Massif

  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 noncommercial quantities; none presently exploited; krill, finfish, and crab have been taken by commercial fisheries
  Land use:
  0% (2015 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:
  the discovery of a large Antarctic ozone hole in the earth's stratosphere (the ozone layer) - first announced in 1985 - spurred the signing of the Montreal Protocol in 1987, an international agreement phasing out the use of ozone-depleting chemicals; the ozone layer prevents most harmful wavelengths of ultra-violet (UV) light from passing through the earth's atmosphere; ozone depletion has been shown to harm a variety of Antarctic marine plants and animals (plankton); in 2002, significant areas of ice shelves disintegrated in response to regional warming; in 2016, a gradual trend toward "healing" of the ozone hole was reported
  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, 98% of the land area is covered by the Antarctic ice sheet, the largest single mass of ice on earth covering an area of 14 million sq km (5.4 million sq mi) and containing 26.5 million cu km (6.4 million cu mi) of ice (this is almost 62% of all of the world's fresh water); if all this ice were converted to liquid water, one estimate is that it would be sufficient to raise the height of the world's oceans by 58 m (190 ft)
- People and Society :: Antarctica
- Population:
  no indigenous inhabitants, but there are both permanent and summer-only staffed research stations
  note: 53 countries have signed the 1959 Antarctic Treaty; 30 of those operate through their National Antarctic Program a number of seasonal-only (summer) and year-round research stations on the continent and its nearby islands south of 60 degrees south latitude (the region covered by the Antarctic Treaty); the population engaging in and supporting science or managing and protecting the Antarctic region varies from approximately 4,400 in summer to 1,100 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

  Legal system:
  Antarctica is administered through annual meetings - known as Antarctic Treaty Consultative Meetings - which include consultative member nations, non-consultative member nations, observer organizations, and expert organizations; decisions from these meetings are carried out by these member nations (with respect to their own nationals and operations) in accordance with their own national laws; more generally, access to the Antarctic Treaty area, that is to all areas between 60 and 90 degrees south latitude, is subject to a number of relevant legal instruments and authorization procedures adopted by the states party to the Antarctic Treaty; note - US law, including certain criminal offenses by or against US nationals, such as murder, may apply extraterritorially; 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, Room 5805, Department of State, Washington, DC 20520, which reports such plans to other nations as required by the Antarctic Treaty; for more information, contact Permit Office, Office of Polar Programs, National Science Foundation, Arlington, Virginia 22230; telephone: (703) 292-8030, or visit its website at www.nsf.gov
- Economy :: Antarctica
- Economy - overview:

  Scientific undertakings rather than commercial pursuits are the predominant human activity in Antarctica. Offshore fishing and tourism, both based abroad, account for Antarctica's limited economic activity.

  Antarctic fisheries, targeting three main species – Chilean sea bass, mackerel, and krill– reported landing 295,000 metric tons in 2013-14. Unregulated fishing is an ongoing problem. The Convention on the Conservation of Antarctic Marine Living Resources determines the recommended catch limits for marine species.

  A total of 36,702 tourists visited the Antarctic Treaty area in the 2014-15 Antarctic summer, slightly lower than the 37,405 visitors in 2013-14. These estimates were provided to the Antarctic Treaty by the International Association of Antarctica Tour Operators and do not include passengers on overflights. Nearly all of the tourists were passengers on commercial ships and several yachts that make trips during the summer.
