Antarctica
Introduction
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 and two maintain the basis for a claim, but most countries do not 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. Also relevant to Antarctic governance are the Environmental Protocol to the Antarctic Treaty and the Convention for the Conservation of Antarctic Marine Living Resources.

Antarctic Region
Area
total: 14.2 million sq km
land: 14.2 million sq km (285,000 sq km ice-free, 13.915 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
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 Treaty consultative parties have made no claims to Antarctic territory, although Russia and the United States have reserved the right to do so, and no country can make a new claim; 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 continuous darkness; persistent high pressure over the interior brings dry, subsiding air that results in very little cloud cover
Terrain
about 99% thick continental ice sheet and 1% 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
highest point: Vinson Massif 4,892 m
lowest point: Denman Glacier more than -3,500 m (-11,500 ft) below sea level
mean elevation: 2,300 m
note: the lowest known land point in Antarctica is hidden in the Denman Glacier; 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; mineral exploitation except for scientific research is banned by the Environmental Protocol to the Antarctic Treaty; krill, icefish, toothfish, and crab have been taken by commercial fisheries, which are managed through the Commission for the Conservation of Antarctic Living Marine Resources (CCAMLR)
Land use
agricultural land: 0% (2018 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; large icebergs may calve from ice shelf
volcanism: volcanic activity on Deception Island and isolated areas of West Antarctica; other seismic activity rare and weak
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, 99% 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
Population
no indigenous inhabitants, but there are both year-round and summer-only staffed research stations
note: 54 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 5,000 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
as of 2017, peak summer (December-February) maximum capacity in scientific stations - 4,877 total; Argentina 601, Australia 243, Belarus 12, Belgium 40, Brazil 66, Bulgaria 22, Chile 433, China 166, Czechia 20, Ecuador 34, Finland 17, France 90, France and Italy jointly 80, Germany 104, India 113, Italy 120, Japan 130, South Korea 130, Netherlands 10, NZ 86, Norway 70, Peru 30, Poland 40, Russia 335, South Africa 80, Spain 98, Sweden 20, Ukraine 24, UK 196, US 1,399, Uruguay 68 (2017)

research stations operated within the Antarctic Treaty area (south of 60 degrees south latitude) by National Antarctic Programs year-round stations - approximately 40 total; Argentina 6, Australia 3, Brazil 1, Chile 6, China 2, France 1, France and Italy jointly 1, Germany 1, India 2, Japan 1, Netherlands 1, South Korea 2, NZ 1, Norway 1, Poland 1, Russia 5, South Africa 1, Ukraine 1, UK 2, US 3, Uruguay 2 (2017)
a range of seasonal-only (summer) stations, camps, and refuges - Argentina, Australia, Belarus, Belgium, Bulgaria, Brazil, Chile, China, Czechia, Ecuador, Finland, France, Germany, India, Italy, Japan, Netherlands, South Korea, New Zealand, Norway, Peru, Poland, Russia, South Africa, Spain, Sweden, Ukraine, UK, US, and Uruguay (2017)
in addition, during the austral summer some nations have numerous occupied locations such as tent camps, summer-long temporary facilities, and mobile traverses in support of research
Environment
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 2016, a gradual trend toward "healing" of the ozone hole was reported; since the 1990s, satellites have shown accelerating ice loss driven by ocean change; although considerable uncertainty remains, scientists are increasing our understanding and ability to model potential impacts of ice loss
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 continuous darkness; persistent high pressure over the interior brings dry, subsiding air that results in very little cloud cover

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, 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 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 extraterritoriality; 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 or 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 2665, Department of State, Washington, DC 20520, which reports such plans to other nations as required by the Antarctic Treaty; for more information, contact antarctica@state.gov
Flag description
unofficial; a True South flag, created in 2018, has quickly become popular for its simple yet elegant design and has been used by various National Antarctic Programs, Antarctic nonprofits, and expedition teams; the flag's meaning is described as: horizontal stripes of navy and white represent the long days and nights at Antarctica's extreme latitude; in the center, a lone white peak erupts from a field of snow and ice, echoing those of the bergs, mountains, and pressure ridges that define the Antarctic horizon; the long shadow it casts forms the unmistakable shape of a compass arrow pointed south, an homage to the continent's legacy of exploration; together, the two center shapes create a diamond, symbolizing the hope that Antarctica will continue to be a center of peace, discovery, and cooperation for generations to come
Economy
Economic 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, within the area covered by the Convention on Conservation of Antarctic Marine Living Resources currently target Patagonian toothfish, Antarctic toothfish, mackerel icefish and Antarctic krill. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) manages these fisheries using the ecosystem-based and precautionary approach. The Commission’s objective is conservation of Antarctic marine living resources and it regulates the fisheries based on the level of information available, and maintaining existing ecological relationships. While Illegal, Unreported and Unregulated (IUU) fishing has declined in the Convention area since 1990, it remains a concern
A total of 73,670 tourists visited the Antarctic Treaty area in the 2019-2020 Antarctic summer, 32 percent greater than the 55,489 visitors in 2018-2019. 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.
