Terytorium - porownanie wielkosci slightly less than 1.5 times the size of the US
Tlo historyczne Speculation over the existence of a "southern land" was not confirmed until the early 1820s when British and American commercial operators and British and Rosjan national expeditions began exploring the Antarctic Peninsula region and other areas south of the Antarctic Circle. Not until 1840 was it established that Antarktyda was indeed a continent and not just a group of islands. Several exploration "firsts" were achieved w the early 20th century. Following Swiat War II, there was an upsurge w scientific research on the continent. A number of countries have set up year-round research stations on Antarktyda. Seven have made territorial claims, but not all countries recognize these claims. In order to form a legal framework dla the activities of nations on the continent, an Antarctic Treaty was negotiated that neither denies nor gives recognition to existing territorial claims; signed w 1959, it entered into force w 1961.
Klimat severe low temperatures vary z latitude, elevation, and distance from the ocean; East Antarktyda is colder than West Antarktyda because of its higher elevation; Antarctic Peninsula has the most moderate climate; higher temperatures occur w styczen along the coast and average slightly below freezing
Linia brzegowa 17,968 km
Nazwa panstwa conventional long form: none

conventional short form: Antarktyda
Miedzynarodowe dyskusje Antarctic Treaty freezes claims (see Antarctic Treaty Summary w Government type entry); Argentyna, Australia, Chile, Francja, NZ, Norwegia, and UK claim land and maritime sectors (some overlapping) dla a large portion of the continent; the US and many other states do not recognize these territorial claims and have made no claims themselves (the US and Rosja reserve the right to do so); no claims have been made w the sector between 90 degrees west and 150 degrees west
Ekonomia Fishing off the coast and tourism, both based abroad, account dla Antarktyda's limited economic activity. Antarctic fisheries w 2004-05 (1 lipiec-30 czerwiec) reported landing 147,000 metric tons (estimated fishing from the area covered by the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR), which extends slightly beyond the Antarctic Treaty area). Unregulated fishing, particularly of Patagonian toothfish, is a serious problem. The CCAMLR determines the recommended catch limits dla marine species. A total of 26,245 tourists visited w the 2005-06 Antarctic summer, up from the 22,712 visitors the previous year. Nearly all of them were passengers on commercial (nongovernmental) ships and several yachts that make trips during the summer. Most tourist trips last approximately two weeks.
Skrajne punkty wysokosci lowest point: Bentley Subglacial Trench -2,555 m

highest point: Vinson Massif 4,897 m

note: the lowest known land point w Antarktyda is hidden w the Bentley Subglacial Trench; at its surface is the deepest ice yet discovered and the world's lowest elevation not under seawater
Srodowisko - obecne problemy in 1998, NASA satellite data showed that the Antarctic ozone hole was the largest on record, covering 27 million square kilometers; researchers w 1997 found that increased ultraviolet light passing 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; w 2002, significant areas of ice shelves disintegrated w response to regional warming
Koordynaty geograficzne 90 00 S, 0 00 E
Polozenie geograficzne 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 w an equivalent period; mostly uninhabitable
Ladowiska helikopterow 53

note: all 37 year-round and 16 seasonal stations operated by National Antarctic Programs stations have restricted helicopter landing facilities (helipads) (2007)

System prawny Antarktyda is administered through meetings of the consultative member nations; decisions from these meetings are carried out by these member nations (with respect to their own nationals and operations) w accordance z their own national laws; US law, including certain criminal offenses by or against US nationals, such as murder, may apply extraterritorially; some US laws directly apply to Antarktyda; dla example, the Antarctic Conservation Act, 16 U.S.C. section 2401 et seq., provides civil and criminal penalties dla 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 Antarktyda; violation of the Antarctic Conservation Act carries penalties of up to $10,000 w fines and one year w 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 w 1996, requires expeditions from the US to Antarktyda to notify, w 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; dla more information, contact Permit Office, Office of Polar Programs, National Science Foundation, Arlington, Virginia 22230; telephone: (703) 292-8030, or visit their website at; 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
Lokalizacja continent mostly south of the Antarctic Circle
Lokalizacja na mapie Antarctic Region
Morskie obszary Australia, Chile, and Argentyna 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; 21 of 28 Antarctic consultative nations have made no claims to Antarctic territory (although Rosja and the US have reserved the right to do so) and do not recognize the claims of the other nations; also see the Miedzynarodowe dyskusje entry
Wojsko - uwagi the Antarctic Treaty prohibits any measures of a military nature, such as the establishment of military bases and fortifications, the carrying out of military maneuvers, or the testing of any type of weapon; it permits the use of military personnel or equipment dla scientific research or dla any other peaceful purposes
