The prefabricated station, which is part of the International Polar Year, was shipped to the South Pole from Belgium by the end of 2008 to monitor the health of the polar regions. New types of meteorites and rare meteorites have been found. In Eastern Antarctica, seed ferns or pteridosperms became abundant and large amounts of sandstone and shale were laid down at this time. [84] It was during this era that Gondwana began to break up. The portion west of the Weddell Sea and east of the Ross Sea is called West Antarctica and the remainder East Antarctica. Towards the end of the Permian period, continued warming led to a dry, hot climate over much of Gondwana. | South Pole 1911-2011", "Pioneers: British Antarctic Expedition 1910—1913", "Antarctic Explorers Timeline: Early 1800s", "Women in Antarctica: Sharing this Life-Changing Experience", "Dates in American Naval History: October", "Børge Ousland: How I crossed Antarctica alone", "O'Brady's Antarctic Crossing: Was It Really Unassisted? [214], Astrophysicists at Amundsen–Scott South Pole Station study the celestial dome and cosmic microwave background radiation. It supports scientific research and protects the continent's ecology. The latter made a temporary landing; while the Wilkes expedition, though it did not make a landing, did remain long enough in the region to survey and map some 800 miles of the continent. This area is dominated by small accumulations of snowfall which becomes ice and thus eventually seaward glacial flows. [143] Antarctic krill, which congregate in large schools, is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, squid, icefish, penguins, albatrosses and many other birds. [43] One month later, the doomed Scott Expedition reached the pole. The largest lake, Vostok, is one of the largest sub-glacial lakes in the world. Antarctica covers more than 14 million km2 (5,400,000 sq mi),[1] making it the fifth-largest continent, about 1.3 times as large as Europe. Antarctica's total area is 14.2 million square kilometers (5.5 million square miles), and it has a total population of 1,106 people. There are no countries in Antarctica, although seven nations claim different parts of it: New Zealand, Australia, France, Norway, the United Kingdom, Chile, and Argentina. [151], A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. If the sheet were to break down, ocean levels would rise by several metres in a relatively short geologically period of time, perhaps a matter of centuries. East Antarctica is largely covered by the East Antarctic Ice Sheet. Country Name. In order to promote peace and security on the Continent, and to determine whether parties to the Antarctic Treaty are meeting their obligations under the Treaty, its Environmental Protocol, and related regulations, the An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year. Antarctica is considered a continent, whereas the Arctic isn’t (see below) because Antarctica is a huge landmass that is then covered in snow and ice on top of, and around the land continent. This ice is formed from the ocean water and floats in the same water and thus does not contribute to a rise in sea level. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. The ice was being held back by a "thread" of ice about 6 km (4 mi) wide,[117][118] prior to its collapse on 5 April 2009.[119][120]. Antarctica is the southernmost continent on Earth. [103] A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may have been influenced by ground temperatures and was not recorded at a height of 2 metres (7 ft) above the surface as required for official air temperature records. Most of the whalers were Norwegian, with an increasing proportion of Britons. [94], The geological study of Antarctica has been greatly hindered by nearly all of the continent being permanently covered with a thick layer of ice. [1], The ISO 3166-1 alpha-2 "AQ" is assigned to the entire continent regardless of jurisdiction. [211] With the ban of CFCs in the Montreal Protocol of 1989, climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070. Several exploration "firsts" were achieved in the early 20th century, but generally the area saw little human activity. [147] The Antarctic fur seal was very heavily hunted in the 18th and 19th centuries for its pelt by sealers from the United States and the United Kingdom. The treaty prohibits military activities, mineral mining, nuclear explosions and nuclear waste disposal. [121] Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. In 1959, Argentina, Australia, Belgium, Chile, the French Republic, Japan, New Zealand, Norway, the Union of South Africa, the Union of the Soviet Socialist Republics, the United Kingdom of Great Britain and Northern Ireland, and the United States of America worked together to create the 1959 Antarctica Treaty. [14] The Roman authors Hyginus and Apuleius (1–2 centuries CE) used for the South Pole the romanised Greek name polus antarcticus,[15][16] from which derived the Old French pole antartike (modern pôle antarctique) attested in 1270, and from there the Middle English pol antartik in a 1391 technical treatise by Geoffrey Chaucer, A Treatise on the Astrolabe, referring to the modern Antarctic Pole. Minor eruptions are frequent, and lava flow has been observed in recent years. No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. [202], There has been some concern over the potential adverse environmental and ecosystem effects caused by the influx of visitors. [108], Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. This conversation led to the 1959 Antarctica Treaty. The hole, reoccurring every spring since the 1970s, was detected by scientists in 1985. Sand and silts were laid down in what is now the Ellsworth, Horlick and Pensacola Mountains. [205], About thirty countries maintain about seventy research stations (40-year-round or permanent, and 30 summer-only) in Antarctica, with an approximate population of 4000 in summer and 1000 in winter. The project includes research in climatology, glaciology and microbiology. [210], Since the 1970s an important focus of study has been the ozone layer in the atmosphere above Antarctica. [1] Despite these new acts, unregulated and illegal fishing, particularly of Patagonian toothfish (marketed as Chilean Sea Bass in the U.S.), remains a serious problem.

[212], In 2007, The Polar Geospatial Center was founded. [13] Marinus of Tyre reportedly used the name in his unpreserved world map from the 2nd century CE. The Polar Geospatial Center uses geospatial and remote sensing technology to provide mapping services to American federally funded research teams. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. The amount of variation it has experienced in its thickness is unclear with satellite techniques just emerging as of 2019. Antarctic Treaty System [65], There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. [17], The long-imagined (but undiscovered) south polar continent was originally called Terra Australis, sometimes shortened to Australia as seen in a woodcut illustration titled "Sphere of the winds", contained in an astrological textbook published in Frankfurt in 1545. [41], During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. The Antarctican dollar, a souvenir item sold in the United States and Canada, is not legal tender. [24] Cook came within about 120 km (75 mi) of the Antarctic coast before retreating in the face of field ice in January 1773. As the treaty states in Article IV, 1.: “Nothing contained in the Treaty shall be interpreted as: (a) a renunciation by any Contracting Party of previously asserted rights of or claims to territorial sovereignty in Antarctica.". [90], Fossil Nothofagus leaves in the Meyer Desert Formation of the Sirius Group show that intermittent warm periods allowed Nothofagus shrubs to cling to the Dominion Range as late as 3–4 Ma (mid-late Pliocene). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness,[5] which extends to all but the McMurdo Dry Valleys and the northernmost reaches of the Antarctic Peninsula.[6]. The Prince Charles Mountains contain significant deposits of iron ore. [50] The first women to step onto the South Pole were Pam Young, Jean Pearson, Lois Jones, Eileen McSaveney, Kay Lindsay and Terry Tickhill in 1969. [56], About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. [136] The ozone hole is attributed to the emission of chlorofluorocarbons or CFCs into the atmosphere, which decompose the ozone into other gases. [54], Roald Amundsen and his crew looking at the Norwegian flag they had raised at the South Pole, 1911, The French Dumont d'Urville Station, an example of modern human settlement in Antarctica. [197] The 1991 Protocol on Environmental Protection to the Antarctic Treaty also restricts a struggle for resources. [131][130] Increased ice outflow has been observed in some regions. [47][48][49], It was not until 31 October 1956, that anyone set foot on the South Pole again; on that day a U.S. Navy group led by Rear Admiral George J. Dufek successfully landed an aircraft there. It was once believed that the lake had been sealed off for 500,000 to one million years, but a recent survey suggests that, every so often, there are large flows of water from one lake to another. Antarctica is a continent unto itself and is not a part of any country. Why? [57] In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation, and so the local mass balance is negative. [125] This loss of ice shelf ''buttressing'' has been identified as the major cause of ice loss on the West Antarctic ice sheet, but has also been observed around the East Antarctic ice sheet. Due to the harsh climate, Antarctica was not colonized. So, does Antarctica have countries? Biologists, in addition to examining the wildlife, are interested in how harsh temperatures and the presence of people affect adaptation and survival strategies in a wide variety of organisms. [35][36] The first recorded and confirmed landing was at Cape Adare in 1895 (by the Norwegian-Swedish whaling ship Antarctic). [204] Qantas resumed commercial overflights to Antarctica from Australia in the mid-1990s. [92], A study from 2014 estimated that during the Pleistocene, the East Antarctic Ice Sheet (EAIS) thinned by at least 500 m (1,600 ft), and that thinning since the Last Glacial Maximum for the EAIS area is less than 50 m (160 ft) and probably started after c. 14 ka. Antarctica, the world’s southernmost continent, is almost wholly covered by an ice sheet and is about 5.5 million square miles (14.2 million square km) in size. This is different from the Magnetic South Pole, because Earth’s geomagnetic and magnetic fields do not perfectly align. The coastline measures 17,968 km (11,165 mi)[1] and is mostly characterised by ice formations, as the following table shows: Antarctica is divided in two by the Transantarctic Mountains close to the neck between the Ross Sea and the Weddell Sea. [209] Medical physicians have made discoveries concerning the spreading of viruses and the body's response to extreme seasonal temperatures. [146] The snow petrel is one of only three birds that breed exclusively in Antarctica. This reduced the formation of the 'polar stratospheric clouds' that enable the chemistry that leads to rapid ozone loss. [18], In the early 19th century, the colonial authorities in Sydney removed the Dutch name from New Holland. Tipping points have been identified in some regions; when a certain threshold warming is reached, these regions may start melting significantly faster and irreversibly. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. The motion of the ice sheet tends to concentrate the meteorites at blocking locations such as mountain ranges, with wind erosion bringing them to the surface after centuries beneath accumulated snowfall. Antarctica is an important geographic location because it is the location of the Earth's South Poles. [123] The extent of sea ice around Antarctica, in terms of square kilometres of coverage, has seen no significant trend in the satellite era (1978–2018), with initial growth being reversed in the last years of the record. BVT. [1][207], Each year, scientists from 28 nations conduct experiments not reproducible in any other place in the world. Different country calling codes and currencies[206] are used for different settlements, depending on the administrating country. The name Antarctica is the romanised version of the Greek compound word ἀνταρκτική (antarktiké), feminine of ἀνταρκτικός (antarktikós),[10] meaning "opposite to the Arctic", "opposite to the north". During clear days in summer, more solar radiation reaches the surface at the South Pole than at the equator because of the 24 hours of sunlight each day at the Pole. It is composed of a metamorphic and igneous platform which is the basis of the continental shield. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape. It is governed and protected by the Antarctic Treaty. Each country currently has claimed a sector of the Antarctic continent that is more or less directly south of its national antarctic-facing lands. [88], Around 25 Ma, the Drake Passage opened between Antarctica and South America, resulting in the Antarctic Circumpolar Current that completely isolated the continent. Antarctica. It is by far the least populated continent, with around 5,000 people in the summer and around 1,000 in the winter. Home to mostly penguins, ice, and a handful of scientists, Antarctica’s inhospitable climate has helped ensure its status as the only continent on … Ozone depletion over Antarctica can cause a cooling of around 6 °C in the local stratosphere. The Great White Continent is governed under a series of recognised guidelines and agreements called the Antarctic Treaty System. They are as follows: These rules meant that Antarctica was to be left to scientific researchers and nature, with a goal for minimal human-derived negative impacts. The Geomagnetic South Pole is where the geomagnetic field intersects the Earth’s surface. Antarctica contains no countries or permanent residents. Due to its location at the South Pole, Antarctica receives relatively little solar radiation except along the southern summer. They searched for a more poetic replacement, suggesting various names such as Ultima and Antipodea. The country is considered politically neutral and it is looked after by the 12 countries that have signed the Antarctic Treaty, including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. [169] He was born in 1978 at Esperanza Base, on the tip of the Antarctic Peninsula;[170][171] his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. While a few of these countries have mutually recognised each other's claims,[175] the validity of these claims is not recognised universally.[1]. [174], Several countries claim sovereignty in certain regions. [64], Antarctica is home to more than 70 lakes that lie at the base of the continental ice sheet. [37], On 22 January 1840, two days after the discovery of the coast west of the Balleny Islands, some members of the crew of the 1837–40 expedition of Jules Dumont d'Urville disembarked on the highest islet[38] of a group of coastal rocky islands about 4 km from Cape Géodésie on the coast of Adélie Land where they took some mineral, algae, and animal samples, erected the French flag and claimed French sovereignty over the territory.[39]. In January 1840, land at Antarctica was discovered for the first time, almost simultaneously, by the United States Exploring Expedition, under Lieut. [107], East Antarctica is colder than its western counterpart because of its higher elevation. The biggest eruption in Antarctica in the last 10,000 years, the volcanic ash was found deposited on the ice surface under the Hudson Mountains, close to Pine Island Glacier. The location of this pole is constantly changing due to magnetic drift, which is caused by the constant movement of iron under the crust, shifting the orientation of Earth’s magnetic field. At 14,200,000 square kilometres (5,500,000 square miles), it is the fifth-largest continent and nearly twice the size of Australia. Legally, Antarctica is not considered a country but a de facto condominium, which is a political territory where several sovereign states agree to share and divide power equally. In fact, it was one of the first major Cold War disarmament actions. Antarctica doesn’t have any of these things. In fact, the only country on earth with more surface area than Antarctica is Russia, which beats it by about a million square miles. [53] For this crossing, Ousland also holds the record for the fastest unsupported journey to the South Pole, taking just 34 days. Earth spins around an axis, and the Geographic South Pole is where the axis intersects Earth’s crust. By the start of the Devonian period (416 Ma), Gondwana was in more southern latitudes and the climate was cooler, though fossils of land plants are known from this time. [124], Melting of floating ice shelves (ice that originated on the land) does not in itself contribute much to sea-level rise, since the ice displaces only its own mass of water. Over time these swamps became deposits of coal in the Transantarctic Mountains. It is roughly the size of the United States and Mexico combined and is almost completely covered by a layer of ice that averages more than one mile in thickness, but is nearly three miles thick in places. That does not mean, however, that no country has tried to claim it in the past or present. [189] On 22 December 2012, the UK ambassador to Argentina, John Freeman, was summoned to the Argentine government as a protest against the claim. [167], The first child born in the southern polar region was a Norwegian girl, Solveig Gunbjørg Jacobsen, born in Grytviken on 8 October 1913, and her birth was registered by the resident British Magistrate of South Georgia. The people who travel to or live in Antarctica fall into two main groups, those who live and work on scientific research stations or bases, and tourists. 155 ] [ 70 ], the ISO 3166-1 alpha-2 `` AQ '' is assigned to the Treaty.
