Lake Zvezda
Lake Zvezda is a large, irregular-shaped glacial lake southeast of Lake Cowan in the east part of Vestfold Hills of Princess Elizabeth Land in Antarctica. The lake was photographed from the air by U.S. Navy Operation Highjump (1946–47) and was mapped from air photos taken by the Soviet Antarctic Expedition (1956) and ANARE (Australian National Antarctic Research Expeditions) (1957–58). It was named Zvezda (star) by the Soviet expedition, and is not to be confused with Braunsteffer Lake Braunsteffer Lake is a glacial lake long located west of the central part of Lake Zvezda in the Vestfold Hills of Princess Elizabeth Land in Antarctica .

Vestfold Hills
The Vestfold Hills are rounded, rocky, coastal hills, in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between in height, with the highest summit reaching nearly . Geography The Vestfold Hills are largely snow and ice-free and are thus classified as an Antarctic oasis. They contain a great variety of lake systems with over 300 lakes and ponds including what is possibly the largest concentration of meromictic (stratified) lakes in the world. This region contains 37 permanently stratified water bodies, including six marine basins and seven seasonally isolated marine basins (SIMBs). These stratified basins also have great variety. They range in salinity from 4 g L−1 to 235 g L−1, in temperature from , in depth from , in area from and surface level from below to above sea level. The region contains ...

Princess Elizabeth Land
Princess Elizabeth Land is the sector of Antarctica between longitude 73° east and Cape Penck (at 87°43' east). The sector is claimed by Australia as part of the Australian Antarctic Territory, although this claim is not widely recognized. Geography Princess Elizabeth Land is located between 64°56'S and 90°00'S and between 73°35' E and 87°43'E. It is divided into two sectors: * Ingrid Christensen Coast, 73°35'E to 81°24'E * Leopold and Astrid Coast, 81°24'E to 87°43'E It is bounded on the west by Amery Ice Shelf, Mac. Robertson Land, and on the east by Kaiser Wilhelm II Land. Exploration Princess Elizabeth Land was discovered on 9 February 1931, by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) (1929–31) under Sir Douglas Mawson. Princess Elizabeth Land was named by Mawson after Princess Elizabeth, granddaughter of King George V who reigned at the time as King of Australia, among his other titles. Princess Elizabeth would later g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-bloc ...

Soviet Antarctic Expedition
The Soviet Antarctic Expedition (SAE or SovAE) (russian: Советская антарктическая экспедиция, САЭ, ''Sovetskaya antarkticheskaya ekspeditsiya'') was part of the Arctic and Antarctic Research Institute of the Soviet Committee on Antarctic Research of the Academy of Sciences of the USSR. The Soviet Union's Ministry of Sea Transport was responsible for the administration, logistics and supply of the expeditions. The first Soviet contact with Antarctica was in January 1947 when the Slava whaling flotilla began whaling in Antarctic waters. Stations The first Soviet Antarctic station, '' Mirny'', was established near the coast on February 13, 1956. This was added to in December 1957 by another station, ''Vostok'' built inland near the south geomagnetic pole. Year-round stations * Mirny (established February 13, 1956) * Vostok (established December 16, 1957) * Novolazarevskaya (established January 18, 1961) * Molodyozhnaya (established January 1 ...

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

Lakes Of Princess Elizabeth Land
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
