Collerson Lake
Collerson Lake is a small, kidney-shaped glacial lake southwest of Club Lake in the Vestfold Hills of Princess Elizabeth Land in Antarctica. A camp was established on the shores of this lake during geological investigations by K. Collerson, geologist at Davis Station in January 1970, for whom it was named by the Antarctic Names Committee of Australia The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands.

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 ...

Club Lake
Club Lake is a glacial saltwater lake in the central part of Breidnes Peninsula in the Vestfold Hills of Princess Elizabeth Land in Antarctica. The lake is long and its irregular shape resembles a club which is elongated northeast–southwest. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and remapped by Australian National Antarctic Research Expeditions (1957–58) who gave the name. It is next west of Lake Jabs, and it is 1.5 nautical miles (3 km) northeast of Collerson Lake Collerson Lake is a small, kidney-shaped glacial lake southwest of Club Lake 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] |
Davis Station
The Davis Station, commonly called Davis, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Davis is situated on the coast of Cooperation Sea in Princess Elizabeth Land, Ingrid Christensen Coast in the Australian Antarctic Territory, a territory claimed by Australia. Davis lies in the Antarctic oasis, a remarkable ice free area known as the Vestfold Hills. Davis was named in honour of Captain John King Davis. Davis was listed on the Register of the National Estate on 26 October 1999 and has been included on the Commonwealth Heritage List as an indicative place, due to the condition of buildings and structures that varies from no longer exists/demolished due to poor condition, through to very good condition. Purpose Davis is a base for scientific research programs including the study of viruses and bacteria using molecular genetic techniques in glacial lakes, the impact of environmental change and pollution ...

Antarctic Names Committee Of Australia
The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands. The committee also issues nominations Governor General for the award of the Australian Antarctic Medal. Committee members were appointed by the Minister or Parliamentary Secretary responsible for Antarctic matters. The committee was founded in 1952 as the Antarctic Names Committee of Australia, and changed to the current name in 1982 to reflect the multiple functions that the committee is responsible for. The committee was replaced by the Australian Antarctic Division Place names Committee in 2015. Features named by the committee * Fyfe Hills, named after W.V. Fyfe, Surveyor General of Western Australia * Goldsworthy Ridge, named after R.W. Goldsworthy, survey field assistant * Gowlett Peaks, named after Alan Gowlett, engineer * Haigh Nunatak, ...

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] |
