Antarctic Specially Managed Areas
An Antarctic Specially Managed Area (ASMA) is a protected area on the continent of Antarctica, or on its adjacent islands. ASMAs are managed by the governments of Brazil, Poland, Ecuador, Peru, United States, New Zealand, Australia, Norway, Spain, United Kingdom, Chile, India, Russia, and Romania. The purpose of the ASMA sites are "to assist in the planning and coordination of activities within a specified area, avoid possible conflicts, improve cooperation between ATCPs and minimise environmental impacts. ASMAs may include areas where activities pose risks of mutual interference or cumulative environmental impacts, as well as sites or monuments of recognised historical value." Unlike the Antarctic Specially Protected Areas, ASMAs do not require a permit to enter.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas Mawson
Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader during the Heroic Age of Antarctic Exploration. Mawson was born in England and came to Australia as an infant. He completed degrees in mining engineering and geology at the University of Sydney. In 1905 he was made a lecturer in petrology and mineralogy at the University of Adelaide. Mawson's first experience in the Antarctic came as a member of Shackleton's ''Nimrod'' Expedition (1907–1909), alongside his mentor Edgeworth David. They were part of the expedition's northern party, which became the first to attain the South Magnetic Pole and to climb Mount Erebus. After his participation in Shackleton's expedition, Mawson became the principal instigator of the Australasian Antarctic Expedition (1911–1914). The expedition explored thousan ...

Southwest Anvers Island And Palmer Basin
Southwest Anvers Island and Palmer Basin is a 3275 km2 Antarctic Specially Managed Area (ASMA 7). It lies towards the northern end of the Antarctic Peninsula, encompassing the south-western coastline of Anvers Island, in the Palmer Archipelago, with the adjacent deep marine waters of the Palmer Basin, the shallower Bismarck Strait, and fringing island groups. Description Features of the south-west coastline of Anvers Island include the United States’ Palmer Station on Arthur Harbour - an LTER site and the principal logistical centre for research within AMSA 7, as well as the ice cliffs of the Marr Ice Piedmont, the ice-free Capes Monaco and Lancaster, and Biscoe Point. The waters of the Palmer Basin extend to a maximum depth of over 1400 m and are surrounded by shallower waters mostly no more than 600 m deep. The island groups include the Rosenthal and Joubin Islands to the north of the Basin, as well as the Wauwermans, Dannebrog and Vedel Islands of ...

Larsemann Hills
The Larsemann Hills are a series of low rounded coastal hills along the southeastern shore of Prydz Bay, Antarctica extending for from Dålk Glacier. They were discovered in February 1935 by Captain Klarius Mikkelsen from the whaling ship ''Thorshavn'', sent out by Norwegian whaling magnate Lars Christensen, and given this name. The bedrock of the Larsemann Hills contains an unusually high abundance of boron and phosphate minerals and is the location of discovery of four new species of mineral. In 2014, the Stornes Peninsula within the Larsemann Hills was declared an Antarctic Specially Protected Area due to its mineral diversity. Research stations As an Antarctic oasis the hills are the home of several Antarctic research stations. * The abandoned original Russian Progress Station. * The relocated new Russian Progress II Station. * The Chinese Zhongshan station * The Australian-donated Romanian Law-Racoviță-Negoiță Station * The India India, officially the Repu ...

Electro-magnetic Interference
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. Both man-made and natural sources generate changing electrical currents and voltages that can cause EMI: ignition systems, cellular network of mobile phones, lightning, solar flares, and auroras (northern/southern lights). EMI frequently affects AM radios. It can also affect mobile phones, FM radios, and televisions, as well as observations for radio astronomy and atmospheric science. EMI can be used intentionally for radio jamming, as in electronic warfare. History Since the earliest days of radio c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amundsen–Scott South Pole Station
The Amundsen–Scott South Pole Station is the United States scientific research station at the South Pole of the Earth. It is the southernmost point under the jurisdiction (not sovereignty) of the United States. The station is located on the high plateau of Antarctica at above sea level. It is administered by the Office of Polar Programs of the National Science Foundation, specifically the United States Antarctic Program (USAP). It is named in honor of Norwegian Roald Amundsen and Briton Robert F. Scott, who led separate teams that raced to become the first to the pole in the early 1900s. The original Amundsen–Scott Station was built by Navy Seabees for the federal government of the United States during November 1956, as part of its commitment to the scientific goals of the International Geophysical Year, an effort lasting from January 1957 through June 1958 to study, among other things, the geophysics of the polar regions of Earth.

Deception Island
Deception Island is an island in the South Shetland Islands close to the Antarctic Peninsula with a large and usually "safe" natural harbor, which is occasionally troubled by the underlying active volcano. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station. It is now a tourist destination with over 15,000 visitors per year. Two research stations are operated by Argentina and Spain during the summer season. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System. Geography Located within the Bransfield Strait, the island is roughly circular and horseshoe-shaped, with a maximum diameter around . The highest peak, Mont Pond on the east side of the island, has an elevation of , while Mount Kirkwood on the west has an elevation of . Over half (57%) of the island is covered by glaciers up to 10 m thick, ice-cored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying on the Indian Ocean side of the continent, separated from West Antarctica by the Transantarctic Mountains. It lies almost entirely within the Eastern Hemisphere and its name has been accepted for more than a century. It is generally higher than West Antarctica and includes the Gamburtsev Mountain Range in the center. The geographic South Pole is located within East Antarctica. Apart from small areas of the coast, East Antarctica is permanently covered by ice and it has relatively low biodiversity, with only a small number of species of terrestrial plants, animals, algae, and lichens. The coasts are the breeding ground for various seabirds and penguins, and the leopard seal, Weddell seal, elephant seal, crabeater seal and Ross seal breed on the surrounding pack ice in summer.

George V Land
George V Land is a segment of Antarctica part of the land claimed as part of the Australian Antarctic Territory, inland from the George V Coast. As with other segments of Antarctica, it is defined by two lines of longitude, 142°02' E and 153°45' E, and by the 60°S parallel. This region was first explored by members of the Main Base party of the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named this feature for King George V of Australia.
