Antarctica Tourism: Tripadvisor has 1, reviews of Antarctica Hotels, Attractions, and Restaurants making it your best Antarctica resource. Antarctica saw two record-high temperatures set between Feb. 6 and Feb.9, and that took a huge toll on the continent's ice, as seen in NASA images. Antarctica just saw its all-time hottest day. Antarctica (/ æ n ˈ t ɑːr k t ɪ k ə / or / æ n t ˈ ɑːr t ɪ k ə / ()) is Earth's southernmost transparency-rights-management.com contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. Antarctica is the coldest, windiest and driest continent. It contains 90 percent of all of the ice on Earth in an area just under times the size of the United States. Affectionately called Mac Town, Antarctica’s largest base, operated by the US, is the central hub for many transiting to the interior. As such, its rough-and-tumble array of buildings can seem like an international adult summer camp.

    Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.

    The aurora australis , commonly known as the southern lights, is a glow observed in the night sky near the South Pole created by the plasma-full solar winds that pass by the Earth.

    Another unique spectacle is diamond dust , a ground-level cloud composed of tiny ice crystals. It generally forms under otherwise clear or nearly clear skies, so people sometimes also refer to it as clear-sky precipitation.

    A sun dog , a frequent atmospheric optical phenomenon , is a bright "spot" beside the true sun. East Antarctica is colder than its western counterpart because of its higher elevation.

    Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods.

    Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1. At the continent's edge, strong katabatic winds off the polar plateau often blow at storm force.

    In the interior, wind speeds are typically moderate. 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.

    Antarctica is colder than the Arctic for three reasons. 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.

    Third, the Earth is at aphelion in July i. The orbital distance contributes to a colder Antarctic winter and a warmer Antarctic summer but the first two effects have more impact.

    Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from to There is some evidence warming in Antarctica is due to human greenhouse gas emissions , [96] but this this is difficult to determine due to internal variability.

    The trend was at a scale unprecedented over the last years; the most dominant driver of this mode of variability is likely the depletion of ozone above the continent.

    In the Antarctic Peninsula's Larsen-B ice shelf collapsed. Due to its location at the South Pole, Antarctica receives relatively little solar radiation except along the southern summer.

    This means that it is a very cold continent where water is mostly in the form of ice. 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.

    Parts of this ice sheet form moving glaciers known as ice streams , which flow towards the edges of the continent. Next to the continental shore are many ice shelves.

    These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year.

    Sea ice extent expands annually in the Antarctic winter and most of this ice melts in the summer. This ice is formed from the ocean water and floats in the same water and thus does not contribute to rise in sea level.

    An possible explanation for the difference between the Antarctic and the Arctic, which has seen rapid sea ice loss, is that thermohaline circulation transports warmed water to deeper layers in the ocean.

    The amount of variation it has experienced in its thickness is unclear with satellite techniques just emerging as of The Antarctic ice sheet is losing mass as ice flows faster into the ocean than before.

    This effect is partially offset by additional snow falling back onto the continent. 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.

    However, ice sheets work as a stabilizer of the land ice, and are vulnerable to warming water. Recent decades have witnessed several dramatic collapses of large ice shelves around the coast of Antarctica, especially along the Antarctic Peninsula.

    This area is dominated by small accumulations of snowfall which becomes ice and thus eventually seaward glacial flows.

    Estimates of the mass balance of the East Antarctic Ice Sheet as a whole range from slightly positive to slightly negative. There is a large area of low ozone concentration or " ozone hole " over Antarctica.

    This hole covers almost the whole continent and was at its largest in September , when the longest lasting hole on record remained until the end of December.

    This reduced the formation of the 'polar stratospheric clouds' that enable the chemistry that leads to rapid ozone loss. Some scientific studies suggest that ozone depletion may have a dominant role in governing climatic change in Antarctica and a wider area of the Southern Hemisphere.

    This cooling has the effect of intensifying the westerly winds which flow around the continent the polar vortex and thus prevents outflow of the cold air near the South Pole.

    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.

    The terrestrial and native year-round species appears to be the descendants of ancestors who lived in geothermally warmed environments during the last ice age, when these areas were the only places on the continent not covered by ice.

    Few terrestrial vertebrates live in Antarctica, and those that do are limited to the sub-Antarctic islands.

    Some species of marine animals exist and rely, directly or indirectly, on the phytoplankton. Antarctic sea life includes penguins , blue whales , orcas , colossal squids and fur seals.

    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 Weddell seal , a " true seal ", is named after Sir James Weddell, commander of British sealing expeditions in the Weddell Sea.

    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.

    A census of sea life carried out during the International Polar Year and which involved some researchers was released in The research is part of the global Census of Marine Life and has disclosed some remarkable findings.

    Large animals such as some cetaceans and birds make the round trip annually. More surprising are small forms of life such as sea cucumbers and free-swimming snails found in both polar oceans.

    About 1, species of fungi have been recorded from Antarctica, of which about are non-lichen-forming and are lichen-forming.

    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.

    In particular, their thick-walled and strongly melanised cells make them resistant to UV light. Those features can also be observed in algae and cyanobacteria , suggesting that these are adaptations to the conditions prevailing in Antarctica.

    This has led to speculation that, if life ever occurred on Mars, it might have looked similar to Antarctic fungi such as Cryomyces antarcticus , and Cryomyces minteri.

    Endemic Antarctic fungi also include certain dung-inhabiting species which have had to evolve in response to the double challenge of extreme cold while growing on dung, and the need to survive passage through the gut of warm-blooded animals.

    About million years ago Permian forests started to cover the continent, and tundra vegetation survived as late as 15 million years ago, [] but the climate of present-day Antarctica does not allow extensive vegetation to form.

    A combination of freezing temperatures, poor soil quality, lack of moisture, and lack of sunlight inhibit plant growth. As a result, the diversity of plant life is very low and limited in distribution.

    The flora of the continent largely consists of bryophytes. There are about species of mosses and 25 species of liverworts , but only three species of flowering plants , all of which are found in the Antarctic Peninsula: Deschampsia antarctica Antarctic hair grass , Colobanthus quitensis Antarctic pearlwort and the non-native Poa annua annual bluegrass.

    Seven hundred species of algae exist, most of which are phytoplankton. Multicoloured snow algae and diatoms are especially abundant in the coastal regions during the summer.

    The Protocol on Environmental Protection to the Antarctic Treaty also known as the Environmental Protocol or Madrid Protocol came into force in , and is the main instrument concerned with conservation and management of biodiversity in Antarctica.

    The Antarctic Treaty Consultative Meeting is advised on environmental and conservation issues in Antarctica by the Committee for Environmental Protection.

    A major concern within this committee is the risk to Antarctica from unintentional introduction of non-native species from outside the region.

    The passing of the Antarctic Conservation Act in the U. The introduction of alien plants or animals can bring a criminal penalty, as can the extraction of any indigenous species.

    The overfishing of krill , which plays a large role in the Antarctic ecosystem, led officials to enact regulations on fishing.

    The Convention for the Conservation of Antarctic Marine Living Resources CCAMLR , a treaty that came into force in , requires that regulations managing all Southern Ocean fisheries consider potential effects on the entire Antarctic ecosystem.

    The illegal fishing of toothfish has been increasing, with estimates of 32, tonnes 35, short tons in Several governments maintain permanent staffed research stations on the continent.

    The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1, in winter to about 5, in the summer, giving it a population density between 70 and inhabitants per million square kilometres and per million square miles at these times.

    Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment.

    An Orthodox church — Trinity Church , opened in at the Russian Bellingshausen Station —is manned year-round by one or two priests, who are similarly rotated every year.

    The first semi-permanent inhabitants of regions near Antarctica areas situated south of the Antarctic Convergence were British and American sealers who used to spend a year or more on South Georgia , from onward.

    During the whaling era, which lasted until , the population of that island varied from over 1, in the summer over 2, in some years to some in the winter.

    Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken , Leith Harbour , King Edward Point , Stromness , Husvik , Prince Olav Harbour , Ocean Harbour and Godthul.

    Managers and other senior officers of the whaling stations often lived together with their families. 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 She was a daughter of Fridthjof Jacobsen, the assistant manager of the whaling station, and Klara Olette Jacobsen.

    Jacobsen arrived on the island in and became the manager of Grytviken, serving from to ; two of his children were born on the island.

    Emilio Marcos Palma was the first person born south of the 60th parallel south , the first born on the Antarctic mainland, and the only living human to be the first born on any continent.

    In , Juan Pablo Camacho was born at the Frei Montalva Station , becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station.

    Several countries claim sovereignty in certain regions. While a few of these countries have mutually recognised each other's claims, [] the validity of these claims is not recognised universally.

    New claims on Antarctica have been suspended since , although in Norway formally defined Queen Maud Land as including the unclaimed area between it and the South Pole.

    The treaty was signed by twelve countries including the Soviet Union and later Russia , the United Kingdom, Argentina, Chile, Australia], and the United States.

    This was the first arms control agreement established during the Cold War. In the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica.

    They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place.

    The Antarctic Treaty prohibits any military activity in Antarctica , including the establishment of military bases and fortifications, military manoeuvres, and weapons testing.

    Military personnel or equipment are permitted only for scientific research or other peaceful purposes. The Argentine, British and Chilean claims all overlap, and have caused friction.

    On 18 December , the British Foreign and Commonwealth Office named a previously unnamed area Queen Elizabeth Land in tribute to Queen Elizabeth II 's Diamond Jubilee.

    The areas shown as Australia's and New Zealand's claims were British territory until they were handed over following the countries' independence. Australia currently claims the largest area.

    The claims of Britain, Australia, New Zealand, France and Norway are all recognised by each other. 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.

    There is current economic activity in Antarctica outside of fishing off the coast and small-scale tourism. Although coal, hydrocarbons , iron ore, platinum , copper , chromium , nickel , gold and other minerals have been found, they have not been in large enough quantities to exploit.

    In , a compromise agreement was reached to place an indefinite ban on mining, to be reviewed in , further limiting economic development and exploitation.

    The primary economic activity is the capture and offshore trading of fish. Antarctic fisheries in —01 reported landing , tonnes.

    Small-scale "expedition tourism" has existed since 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.

    Travel is largely by small or medium ship, focusing on specific scenic locations with accessible concentrations of iconic wildlife.

    A total of 37, tourists visited during the —07 Austral summer with nearly all of them coming from commercial ships; 38, were recorded in — There has been some concern over the potential adverse environmental and ecosystem effects caused by the influx of visitors.

    Some environmentalists and scientists have made a call for stricter regulations for ships and a tourism quota. Antarctic sightseeing flights which did not land operated out of Australia and New Zealand until the fatal crash of Air New Zealand Flight in on Mount Erebus, which killed all aboard.

    About thirty countries maintain about seventy research stations year-round or permanent, and 30 summer-only in Antarctica, with an approximate population of in summer and in winter.

    The ISO alpha-2 "AQ" is assigned to the entire continent regardless of jurisdiction. Different country calling codes and currencies [] are used for different settlements, depending on the administrating country.

    The Antarctican dollar, a souvenir item sold in the United States and Canada, is not legal tender. Each year, scientists from 28 different nations conduct experiments not reproducible in any other place in the world.

    In the summer more than 4, scientists operate research stations; this number decreases to just over 1, in the winter.

    Researchers include biologists , geologists , oceanographers , physicists , astronomers , glaciologists , and meteorologists. Geologists tend to study plate tectonics , meteorites from outer space , and resources from the breakup of the supercontinent Gondwana.

    Glaciologists in Antarctica are concerned with the study of the history and dynamics of floating ice, seasonal snow , glaciers, and ice sheets.

    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.

    Medical physicians have made discoveries concerning the spreading of viruses and the body's response to extreme seasonal temperatures. Astrophysicists at Amundsen—Scott South Pole Station study the celestial dome and cosmic microwave background radiation.

    Many astronomical observations are better made from the interior of Antarctica than from most surface locations because of the high elevation, which results in a thin atmosphere; low temperature, which minimises the amount of water vapour in the atmosphere; and absence of light pollution , thus allowing for a view of space clearer than anywhere else on Earth.

    Since the s an important focus of study has been the ozone layer in the atmosphere above Antarctica. In , 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.

    It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons CFCs emitted by human products.

    In , The Polar Geospatial Center was founded. The Polar Geospatial Center uses geospatial and remote sensing technology to provide mapping services to American federally funded research teams.

    The prefabricated station, which is part of the International Polar Year, was shipped to the South Pole from Belgium by the end of to monitor the health of the polar regions.

    The project includes research in climatology , glaciology and microbiology. In January British Antarctic Survey BAS scientists, led by Hugh Corr and David Vaughan , reported in the journal Nature Geoscience that 2, years ago, a volcano erupted under Antarctica's ice sheet based on airborne survey with radar images.

    The biggest eruption in Antarctica in the last 10, years, the volcanic ash was found deposited on the ice surface under the Hudson Mountains , close to Pine Island Glacier.

    Meteorites from Antarctica are an important area of study of material formed early in the solar system ; most are thought to come from asteroids , but some may have originated on larger planets.

    The first meteorite was found in and named the Adelie Land meteorite. In , a Japanese expedition discovered nine meteorites.

    Most of these meteorites have fallen onto the ice sheet in the last million years. 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.

    Compared with meteorites collected in more temperate regions on Earth, the Antarctic meteorites are well-preserved. 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.

    New types of meteorites and rare meteorites have been found. Among these are pieces blasted off the Moon, and probably Mars, by impacts. These specimens, particularly ALH discovered by ANSMET , are at the centre of the controversy about possible evidence of microbial life on Mars.

    Because meteorites in space absorb and record cosmic radiation, the time elapsed since the meteorite hit the Earth can be determined from laboratory studies.

    The elapsed time since fall, or terrestrial residence age, of a meteorite represents more information that might be useful in environmental studies of Antarctic ice sheets.

    In January , reports emerged of a 2-kilometre 1. Satellite images from 25 years ago seemingly show it. North America.

    A subsequent treaty, called the Madrid Protocol adopted in prohibited mining, required evironmental impact assessments for new activities, and designated the continent as a natural reserve.

    Knowledge about Antarctica has increased greatly since the IGY. Until the s, scientists relied on ground-based geophysical techniques such as seismic surveys of the Antarctic ice sheets to reveal hidden mountain ranges and peaks.

    Advances in radar technology since then have resulted in airborne radio -echo sounding systems that can measure ice-thickness, which has enabled scientific teams to make systematic remote surveys of ice-buried terrains.

    Satellites and other remote-sensing technologies have become key tools in providing mapping data. The ice-choked and stormy seas around Antarctica long hindered exploration by wooden-hulled ships.

    No lands break the relentless force of the prevailing west winds as they race clockwise around the continent, dragging westerly ocean currents along beneath.

    The southernmost parts of the Atlantic, Pacific, and Indian oceans converge into a cold oceanic water mass with unique biological and physical characteristics.

    Early penetration of this Southern or Antarctic Ocean in the search for fur seals led in to the discovery of the continent. Icebreakers and aircraft now make access relatively easy, although still not without hazard in inclement conditions.

    The familiar map boundaries of the continent known as Antarctica, defined as the South Polar landmass and all its nonfloating grounded ice , are subject to change with current and future climate change.

    The continent was ice-free during most of its lengthy geologic history, and there is no reason to believe it will not become so again.

    As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting. At sea, this exposes more of the dark ocean below the ice, and on land, the dark vegetation below.

    These dark surfaces then absorb the solar radiation causing more melting. This creates a positive feedback loop, which exacerbates the impacts of climate change.
