In 1997 Børge Ousland became the first person to make a solo crossing. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Antarctic Treaty, (Dec. 1, 1959), agreement signed by 12 nations, in which the Antarctic continent was made a demilitarized zone to be preserved for scientific research. The only place you can with drawl cash in Antarctica is at the … These are floating extensions of outflowing glaciers from the continental ice mass. Antarctica had been the only continent spared of the pandemic, which has infected more than 77.6 million people and killed more than 1.7 million … [59], In September 2018, researchers at the National Geospatial-Intelligence Agency released a high resolution terrain map (detail down to the size of a car, and less in some areas) of Antarctica, named the "Reference Elevation Model of Antarctica" (REMA).[60]. So far, 46 countries … Antarctica (/ænˈtɑːrtɪkə/ or /æntˈɑːrktɪkə/ (listen))[note 1] is Earth's southernmost continent. Explorer Matthew Flinders, in particular, has been credited with popularising the transfer of the name Terra Australis to Australia. Antarctic Treaty, (Dec. 1, 1959), agreement signed by 12 nations, in which the Antarctic continent was made a demilitarized zone to be preserved for scientific research. Minor eruptions are frequent, and lava flow has been observed in recent years. [133][134][135] As of 2015, there are two Wells Fargo ATMs in Antarctica.[136]. As much as people might want to think that … The apparently simple morphology, scarcely differentiated structures, metabolic systems and enzymes still active at very low temperatures, and reduced life cycles shown by such fungi make them particularly suited to harsh environments such as the McMurdo Dry Valleys. West Antarctica is covered by the West Antarctic Ice Sheet. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. [160], East Antarctica is a cold region with a ground base above sea level and occupies most of the continent. [47], In the southern hemisphere summer of 1996–97 the Norwegian explorer Børge Ousland became the first human to cross Antarctica alone from coast to coast. As of April 2010, 17 additional nations (Brazil, Bulgaria, China, Czech Republic, Ecuador, Finland, Germany, India, Italy, Netherlands, Peru, Poland, Republic of Korea, Spain, Sweden, Ukraine, and Uruguay) … Over time these swamps became deposits of coal in the Transantarctic Mountains. A sun dog, a frequent atmospheric optical phenomenon, is a bright "spot" beside the true sun. If all of this ice were melted, sea levels would rise about 60 m (200 ft). Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. 14. [48] Ousland got aid from a kite on parts of the distance. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. 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 northernmost reaches of the Antarctic Peninsula. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. found instead that the net change in ice mass is slightly positive at approximately 82 gigatonnes per year (with significant regional variation) which would result in Antarctic activity reducing global sea-level rise by 0.23 mm per year. [68] The ice began to spread, replacing the forests that until then had covered the continent. Courtesy of Antarctica Flights. Twelve Countries Antarctica is defined as all land and ice shelves south of 60’S the purposes of the Treaty System. At the edge of the continent, strong katabatic winds off the polar plateau often blow at storm force. East Antarctica is largely covered by the East Antarctic Ice Sheet. This area is dominated by small accumulations of snowfall which becomes ice and thus eventually seaward glacial flows. However, there is some evidence of antarctic marine glaciation during the Cretaceous period.[65]. The occasion was known as the International Geophysical Year (IGY), a worldwide event that actually involved 18 months of gathering and sharing data concerning the earth’s natural phenomena. Other dormant volcanoes may potentially be active. [142], In 2007 The Polar Geospatial Center was founded. Due to its location at the South Pole, Antarctica receives relatively little solar radiation except along the southern summer. [105] Growth is restricted to a few weeks in the summer. Antarctica is noted as the last region on Earth in recorded history to be discovered, unseen until 1820 when the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny sighted the Fimbul ice shelf. In 1983 the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. [69], 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). Next to the continental shore are many ice shelves. Not all vessels associated with Antarctic tourism are members of IAATO, but IAATO members account for 95% of the tourist activity. [citation needed] Several Antarctic ice streams, which account for about 10% of the ice sheet, flow to one of the many Antarctic ice shelves: see ice-sheet dynamics. [108], The passing of the Antarctic Conservation Act (1978) in the U.S. brought several restrictions to U.S. activity on Antarctica. The Treaty entered into force on 23 June 1961; the 12 signatories became the original 12 consultative nations. [92], Few terrestrial vertebrates live in Antarctica, and those that do are limited to the sub-Antarctic islands. [149], In January 2013, an 18 kg (40 lb) meteorite was discovered frozen in ice on the Nansen ice field by a Search for Antarctic Meteorites, Belgian Approach (SAMBA) mission.[150]. Become a Study.com member to unlock this The Antarctic Treaty contained many provisions that would help prevent any conflict over land claims: The 1959 Antarctic Treaty. More than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). Since then, another 41 countries have agreed to the treaty. In Eastern Antarctica, seed ferns or pteridosperms became abundant and large amounts of sandstone and shale were laid down at this time. Researchers include biologists, geologists, oceanographers, physicists, astronomers, glaciologists, and meteorologists. It used to be ice-free until about 34 million years ago, when it became covered with ice. All other trademarks and copyrights are the property of their respective owners. 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. The first official use of the name Antarctica as a continental name in the 1890s is said to have been used by Scottish cartographer John George Bartholomew. The emperor penguin is the only penguin that breeds during the winter in Antarctica; it and the Adélie penguin breed farther south than any other penguin. According to various organisations (the National Science Foundation,[23] NASA,[24] the University of California, San Diego,[25] the Russian State Museum of the Arctic and Antarctic,[26] among others),[27][28] ships captained by three men sighted Antarctica or its ice shelf in 1820: Fabian Gottlieb von Bellingshausen (a captain in the Imperial Russian Navy), Edward Bransfield (a captain in the Royal Navy), and Nathaniel Palmer (a sealer from Stonington, Connecticut). Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size. At 0.00008 people per square kilometre, it is by far the least densely populated continent. [176], A study published in Nature Geoscience in 2013 identified central West Antarctica as one of the fastest-warming regions on Earth. This sediment uplift was accompanied by igneous intrusions and volcanism. The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910. Besides the seven countries that were also busy claiming the territories, five more came forward, willing to ratify the treaty. The flora of the continent largely consists of bryophytes. Lake Vostok, discovered beneath Russia's Vostok Station in 1996, is the largest of these subglacial lakes. [131] The 1991 Protocol on Environmental Protection to the Antarctic Treaty also restricts a struggle for resources. [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. In coastal areas such as Shackleton Range and Victoria Land some faulting has occurred. [62] The Antarctic Peninsula was formed by uplift and metamorphism of sea bed sediments during the late Paleozoic and the early Mesozoic eras. However, it is the outflow of the ice from the land to form the ice shelf which causes a rise in global sea level. Antarctica is the most isolated of the seven continents, and is called home only by penguins and a few other species of animals, as well as scientific researchers from around the world. [77] Antarctica is a frozen desert with little precipitation; the South Pole receives less than 10 mm (0.4 in) per year, on average. [106] Bacteria have been found living in the cold and dark as deep as 800 m (0.50 mi; 2,600 ft) under the ice. While a few of these countries have mutually recognised each other's claims,[111] the validity of these claims is not recognised universally.[1]. The International Geophysical Year (IGY) of 1957-58 aimed to end Cold War divisions among the scientific community by promoting global scientific exchange. 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. It is the only continent that has no indigenous human populations. The largest lake, Vostok, is one of the largest sub-glacial lakes in the world. [157], A single 2015 study by H. Jay Zwally et al. [94] Another member of Chironomidae is Parochlus steinenii. This study also noted that West Antarctica has warmed by more than 0.1 °C (0.2 °F) per decade in the last 50 years, and this warming is strongest in winter and spring. He justified the titling of his book A Voyage to Terra Australis (1814) by writing in the introduction: There is no probability, that any other detached body of land, of nearly equal extent, will ever be found in a more southern latitude; the name Terra Australis will, therefore, remain descriptive of the geographical importance of this country and of its situation on the globe: it has antiquity to recommend it; and, having no reference to either of the two claiming nations, appears to be less objectionable than any other which could have been selected. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. [132], Small-scale "expedition tourism" has existed since 1957 and is currently subject to Antarctic Treaty and Environmental Protocol provisions, but in effect self-regulated by the International Association of Antarctica Tour Operators (IAATO). [162][164], Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. Discovery and claim of French sovereignty over Adélie Land by Jules Dumont d'Urville, in 1840. All previous land claims would become obsolete. What countries are in Antarctica continent? Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. The coronavirus has landed in Antarctica, the … [42][43][44], 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. [126], Other countries participating as members of the Antarctic Treaty have a territorial interest in Antarctica, but the provisions of the Treaty do not allow them to make their claims while it is in force. [100][106], Seven hundred species of algae exist, most of which are phytoplankton. Temperatures reach a minimum of between −80 °C (−112 °F) and −89.2 °C (−128.6 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Antarctic ice serves as both the shield and the detection medium for the largest neutrino telescope in the world, built 2 km (1.2 mi) below Amundsen–Scott station. The portion west of the Weddell Sea and east of the Ross Sea is called West Antarctica and the remainder East Antarctica. There is a waterfall in Antarctica, known as the “Blood Falls,” that has a high amount of iron and is … All attempted crossings, with no kites or resupplies, that have tried to go from the true continental edges, where the ice meets the sea, have failed due to the great distance that needs to be covered. The 30 countries working on Antarctica have imposed strict safety requirements in an attempt to prevent a Covid-19 outbreak on the continent, including significant reductions to … During that period, geographers had to make do with clumsy phrases such as "the Antarctic Continent". In 1895, the first confirmed landing was conducted by a team of Norwegians. Additionally, Australia, Georgia, New Zealand, Norway and the United Kingdom claim the island territories within the Convergence that surround Antarctica. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. 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. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. [98], A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. As a result, the continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. Johan Berte is the leader of the station design team and manager of the project which conducts research in climatology, glaciology and microbiology. Earn Transferable Credit & Get your Degree. Managers and other senior officers of the whaling stations often lived together with their families. [1], The ISO 3166-1 alpha-2 "AQ" is assigned to the entire continent regardless of jurisdiction. Best Countries » Best States » ... Antarctica had been the only continent spared of the pandemic, which has infected more than 77.6 million people around the … Richard E. Byrd led several voyages to the Antarctic by plane in the 1930s and 1940s. [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. Various factors may aid in their distribution – fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 °C, and the major current systems or marine conveyor belt which transport eggs and larval stages. As a result, the diversity of plant life is very low and limited in distribution. If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. Forty … [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. Antarctica is one of the Earth's seven continents. Additionally, Australia, Georgia, New Zealand, Norway and the United Kingdom claim the island territories within the Convergence that surround Antarctica. If you’ve seen my list of how many countries in the world you’ll notice that none of them are part of Antarctica. It dedicates the continent to peaceful research activities. The ice was being held back by a "thread" of ice about 6 km (4 mi) wide,[172][173] prior to its collapse on 5 April 2009. The continent is surrou… Robertson Land, Wilkes Land, and Victoria Land. The geological study of Antarctica has been greatly hindered by nearly all of the continent being permanently covered with a thick layer of ice. [52] 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. For the past 14 million years, it has been the frigid continent that persists today. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. Sciences, Culinary Arts and Personal Since about 15 Ma, the continent has been mostly covered with ice. The Antarctic Treaty was negotiated by 12 countries in 1959: Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, UK, USA and USSR. The most valuable resources of Antarctica lie offshore, namely the oil and natural gas fields found in the Ross Sea in 1973. The Antarctic Treaty was signed in 1959 by the 12 countries who then had a presence in Antarctica. As plate tectonics shifted other continents, Antarctica became colder and drier. The Antarctic Peninsula began to form during the Jurassic period (206–146 Ma), and islands gradually rose out of the ocean. 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. Some environmentalists and scientists have made a call for stricter regulations for ships and a tourism quota. [148], In 2006, a team of researchers from Ohio State University used gravity measurements by NASA's GRACE satellites to discover the 500-kilometre-wide (300 mi) Wilkes Land crater, which probably formed about 250 million years ago. The Antarctic Treaty set the foundation for how affairs are conducted in Antarctica today. [114] A coalition of international organisations[115] launched a public pressure campaign to prevent any minerals development in the region, led largely by Greenpeace International,[116] which operated its own scientific station—World Park Base—in the Ross Sea region from 1987 until 1991[117] and conducted annual expeditions to document environmental effects of humans on Antarctica. Countries who have signed the treaty can either be ‘consultative’ or ‘non-consultative’. ", "Fastest unsupported (kite assisted) journey to the South Pole taking just 34 days", "Snow in the McMurdo Dry Valleys, Antarctica", "Scientists Discover Undersea Volcano Off Antarctica", "New Antarctica Map Is Like 'Putting on Glasses for the First Time and Seeing 20/20' – A high resolution terrain map of Earth's frozen continent will help researchers better track changes on the ice as the planet warms", "Temperate rainforests near the South Pole during peak Cretaceous warmth", "Anatomy of a basal sauropodomorph dinosaur from the Early Jurassic Hanson Formation of Antarctica", "Antarctica yields first land mammal fossil", "New CO2 data helps unlock the secrets of Antarctic formation", "A forest grows in Antarctica. Among these are pieces blasted off the Moon, and probably Mars, by impacts. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. [180] Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent. Antarctica is the only continent that was literally discovered, because it has no native hu… The first meteorite was found in 1912 and named the Adelie Land meteorite. Antarctic fisheries in 2000–01 reported landing 112,934 tonnes. These countries... Our experts can answer your tough homework and study questions. For a table of sovereign states and dependent territories in Africa with geographical data such as area, population, and population density, see here. This ice is formed from the ocean water and floats in the same water and thus does not contribute to rise in sea level. Sheperd et al. [112] Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. Antarctica contains many other mountains, on both the main continent and the surrounding islands. Its lands (and ice and snow) have no nationality in the way that we understand it in the rest of the world. [69] It was first recorded near the Beardmore Glacier by Frank Wild on the Nimrod Expedition, and now low-grade coal is known across many parts of the Transantarctic Mountains. The name Antarctica is the romanised version of the Greek compound word ἀνταρκτική (antarktiké), feminine of ἀνταρκτικός (antarktikós),[9] meaning "opposite to the Arctic", "opposite to the north". Africa is the world's second-largest and second-most-populous continent. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Many countries conducted their first Antarctic explorations and constructed the first research stations on Antarctica. More than 50 Antarctic stations were established for the IGY by just 12 countries: Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the Soviet Union, the United Kingdom, and the United States. [125] Argentine–UK relations had previously been damaged throughout 2012 due to disputes over the sovereignty of the nearby Falkland Islands, and the 30th anniversary of the Falklands War. Most of the whalers were Norwegian, with an increasing proportion of Britons. [107], The Protocol on Environmental Protection to the Antarctic Treaty (also known as the Environmental Protocol or Madrid Protocol) came into force in 1998, and is the main instrument concerned with conservation and management of biodiversity in Antarctica. East Antarctica is geologically varied, dating from the Precambrian era, with some rocks formed more than 3 billion years ago. The overfishing of krill, which plays a large role in the Antarctic ecosystem, led officials to enact regulations on fishing. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. Most of these meteorites have fallen onto the ice sheet in the last million years. [122] The only documented military land manoeuvre has been the small Operation NINETY by the Argentine military in 1965.[123]. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. Ongoing experiments are conducted by more than 4,000 scientists from many nations. [177], In February 2020, the region recorded the highest temperature of 18.3 °C (64.9 °F), which was a degree higher than the previous record of 17.5 °C (63.5 °F) in March 2015. https://trulytraveled.com/travel-destinations/travel-guides/countries-in-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. 35,000 short tons ) in 2000 Convergence that surround Antarctica sensing technology provide!
