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.	A decision by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude which coincides with the Antarctic Treaty Limit. The Southern Ocean is now the fourth largest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).
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	sea temperatures vary from about 10 degrees Celsius to -2 degrees Celsius; cyclonic storms travel eastward around the continent and frequently are intense because of the temperature contrast between ice and open ocean; the ocean area from about latitude 40 south to the Antarctic Circle has the strongest average winds found anywhere on Earth; in winter the ocean freezes outward to 65 degrees south latitude in the Pacific sector and 55 degrees south latitude in the Atlantic sector, lowering surface temperatures well below 0 degrees Celsius; at some coastal points intense persistent drainage winds from the interior keep the shoreline ice-free throughout the winter

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	Antarctic Treaty defers claims (see Antarctic Treaty Summary in the Antarctica 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 maritime claims of other nations and have made no claims themselves (the US and Russia have reserved the right to do so); no formal 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.	Fisheries in 1998-99 (1 July to 30 June) landed 119,898 metric tons, of which 85% was krill and 14% Patagonian toothfish. International agreements were adopted in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 1998-99 season landed five to six times more Patagonian toothfish than the regulated fishery. In the 1999-2000 antarctic summer 13,193 tourists, most of them seaborne, visited the Southern Ocean and Antarctica, compared to 10,013 the previous year. Nearly 16,000 tourists are expected during the 2000-01 season.
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	lowest point: -7,235 m at the southern end of the South Sandwich Trench highest point: sea level 0 m
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	increased solar ultraviolet radiation resulting from the Antarctic ozone hole in recent years, reducing marine primary productivity (phytoplankton) by as much as 15% and damaging the DNA of some fish; illegal, unreported, and unregulated fishing in recent years, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, which is likely to affect the sustainability of the stock; large amount of incidental mortality of seabirds resulting from long-line fishing for toothfish note: the now-protected fur seal population is making a strong comeback after severe overexploitation in the 18th and 19th centuries
Environment - international agreements	-	the Southern Ocean is subject to all international agreements regarding the world's oceans; in addition, it is subject to these agreements specific to the Antarctic region: International Whaling Commission (prohibits commercial whaling south of 40 degrees south [south of 60 degrees south between 50 degrees and 130 degrees west]); Convention on the Conservation of Antarctic Seals (limits sealing); Convention on the Conservation of Antarctic Marine Living Resources (regulates fishing) note: many nations (including the US) prohibit mineral resource exploration and exploitation south of the fluctuating Polar Front (Antarctic Convergence) which is in the middle of the Antarctic Circumpolar Current and serves as the dividing line between the very cold polar surface waters to the south and the warmer waters to the north
Geographic coordinates	90 00 S, 0 00 E	65 00 S, 0 00 E (nominally), but the Southern Ocean has the unique distinction of being a large circumpolar body of water totally encircling the continent of Antarctica; this ring of water lies between 60 degrees south latitude and the coast of Antarctica, and encompasses 360 degrees of longitude
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	the major chokepoint is the Drake Passage between South America and Antarctica; the Polar Front (Antarctic Convergence) is the best natural definition of the northern extent of the Southern Ocean; it is a distinct region at the middle of the Antarctic Circumpolar Current that separates the very cold polar surface waters to the south from the warmer waters to the north; the Front and the Current extend entirely around Antarctica, reaching south of 60 degrees south near New Zealand and near 48 degrees south in the far South Atlantic coinciding with the path of the maximum westerly winds

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.
