Field Background: For all countries in alphabetical order
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 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.

Field Background: For all countries in alphabetical order
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; 21 of 28 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:
Field Background: For all countries in alphabetical order
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:
Field Background: For all countries in alphabetical order
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
Elevation extremes:
Field Background: For all countries in alphabetical order
lowest point: Bentley Subglacial Trench -2,540 m
highest point: Vinson Massif 4,897 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 seawater
Natural resources:
Field Background: For all countries in alphabetical order
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

other: 100% (ice 98%, barren rock 2%) (2011)
Natural hazards:
Field Background: For all countries in alphabetical order
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:
Field Background: For all countries in alphabetical order
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 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; in 2002, significant areas of ice shelves disintegrated in response to regional warming
Geography - note:
Field Background: For all countries in alphabetical order
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

Antarctic Treaty Summary - the Antarctic region is governed by a system known as the Antarctic Treaty System; the system includes: 1. the Antarctic Treaty, signed on 1 December 1959 and entered into force on 23 June 1961, which establishes the legal framework for the management of Antarctica, 2. Recommendations and Measures adopted at meetings of Antarctic Treaty countries, 3. The Convention for the Conservation of Antarctic Seals (1972), 4. The Convention for the Conservation of Antarctic Marine Living Resources (1980), and 5. The Protocol on Environmental Protection to the Antarctic Treaty (1991); the 33rd Antarctic Treaty Consultative Meeting was held in Punta del Este, Uruguay in May 2010; at these periodic meetings, decisions are made by consensus (not by vote) of all consultative member nations; by April 2010, there were 48 treaty member nations: 28 consultative and 20 non-consultative; consultative (decision-making) members include the seven nations that claim portions of Antarctica as national territory (some claims overlap) and 21 non-claimant nations; the US and Russia have reserved the right to make claims; the US does not recognize the claims of others; Antarctica 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) in accordance with their own national laws; the years in parentheses indicate when a consultative member-nation acceded to the Treaty and when it was accepted as a consultative member, while no date indicates the country was an original 1959 treaty signatory; claimant nations are - Argentina, Australia, Chile, France, NZ, Norway, and the UK; nonclaimant consultative nations are - Belgium, Brazil (1975/1983), Bulgaria (1978/1998), China (1983/1985), Ecuador (1987/1990), Finland (1984/1989), Germany (1979/1981), India (1983/1983), Italy (1981/1987), Japan, South Korea (1986/1989), Netherlands (1967/1990), Peru (1981/1989), Poland (196
Legal system:
Field Background: For all countries in alphabetical order
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:
Economy - overview:
Field Background: For all countries in alphabetical order
Scientific undertakings rather than commercial pursuits are the predominate human activity in Antarctica. Fishing off the coast and tourism, both based abroad, account for Antarctica's limited economic activity. Antarctic fisheries, targeting three main species - Patagonian and Antarctic toothfish (Dissostichus eleginoides and D. mawsoni), mackerel icefish (Champsocephalus gunnari), and krill (Euphausia superba) - reported landing 141,147 metric tons in 2008-09 (1 July - 30 June). (Estimated fishing is 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 (also known as Chilean sea bass), is a serious problem. The CCAMLR determines the recommended catch limits for marine species. A total of 37,858 tourists visited the Antarctic Treaty area in the 2008-09 Antarctic summer, down from the 46,265 visitors in 2007-08 (estimates provided to the Antarctic Treaty by the International Association of Antarctica Tour Operators (IAATO); this does not include passengers on overflights). Nearly all of them were passengers on commercial (nongovernmental) ships and several yachts that make trips during the summer.
