[122] The only documented military land manoeuvre has been the small Operation NINETY by the Argentine military in 1965.[123]. While a few of these countries have mutually recognised each other's claims, the validity of these claims is not recognised universally. Integral to the story of the origin of Antarctica's name is that it was not named Terra Australis—this name was given to Australia instead, because of the misconception that no significant landmass could exist further south. [citation needed], 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. This happened three days before Bransfield sighted the land of the Trinity Peninsula of Antarctica, as opposed to the ice of an ice shelf, and ten months before Palmer did so in November 1820. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia and the United States. 22 Dec 2020 - 19:31 GMT Coronavirus reaches end of earth as first outbreak hits Antarctica. Africa is the world's second-largest and second-most-populous continent. The flightless midge Belgica antarctica, up to 6 mm (1⁄4 in) in size, is the largest purely terrestrial animal in Antarctica. [14], 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. It is governed and protected by the Antarctic Treaty. [133][134][135] As of 2015, there are two Wells Fargo ATMs in Antarctica.[136]. Antarctica is often listed as the 7th, and final, continent. 2012, found that different satellite methods for measuring ice mass and change were in good agreement and combining methods leads to more certainty with East Antarctica, West Antarctica, and the Antarctic Peninsula changing in mass by +14 ± 43, −65 ± 26, and −20 ± 14 gigatonnes (Gt) per year. Is there land under the ice in Antarctica? [171] Between 28 February and 8 March 2008, about 570 km2 (220 sq mi) of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 km2 (5,800 sq mi) of the ice shelf at risk. The continent has about 90% of the world's ice (and thus about 70% of the world's fresh water). Glaciation began at the end of the Devonian period (360 Ma), as Gondwana became centred on the South Pole and the climate cooled, though flora remained. The only people who live there are researchers and support personnel. [45] 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. [108], The passing of the Antarctic Conservation Act (1978) in the U.S. brought several restrictions to U.S. activity on Antarctica. 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. In January 2015, reports emerged of a 2-kilometre (1.2 mi) circular structure, supposedly a meteorite crater, on the surface snow of King Baudouin Ice Shelf. She was a daughter of Fridthjof Jacobsen, the assistant manager of the whaling station, and Klara Olette Jacobsen. More than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). [99], About 1,150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming. The geological study of Antarctica has been greatly hindered by nearly all of the continent being permanently covered with a thick layer of ice. [15], In the nineteenth century, the colonial authorities in Sydney removed the Dutch name from New Holland. Exploitation of all mineral resources is banned until 2048 by the Protocol on Environmental Protection to the Antarctic Treaty. A major concern within this committee is the risk to Antarctica from unintentional introduction of non-native species from outside the region. Synapsids, commonly known as "mammal-like reptiles", were common in Antarctica during the Early Triassic and included forms such as Lystrosaurus. [131] The 1991 Protocol on Environmental Protection to the Antarctic Treaty also restricts a struggle for resources. Instead, the 12 signatory nations would be given mutual sovereignty of the continent. In 1998, a compromise agreement was reached to place an indefinite ban on mining, to be reviewed in 2048, further limiting economic development and exploitation. [148], This large collection of meteorites allows a better understanding of the abundance of meteorite types in the solar system and how meteorites relate to asteroids and comets. These specimens, particularly ALH84001 discovered by ANSMET, are at the centre of the controversy about possible evidence of microbial life on Mars. [138], 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. Those features can also be observed in algae and cyanobacteria, suggesting that these are adaptations to the conditions prevailing in Antarctica.
