Ozero Veretenu
Lake Vereteno is a narrow glacial lake, long, located in the northeast part of Breidnes Peninsula, Vestfold Hills in Princess Elizabeth Land of Antarctica. The lake is approximately south of Luncke Ridge. The lake was first photographed by U.S. Navy Operation Highjump (1946–47), and subsequently by ANARE (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 involv ...) (1954–58), and the Soviet Antarctic Expedition (1956). It was named Ozero Veretenu (Spindle Lake) by the latter.

Breidnes Peninsula
Breidnes Peninsula () is a rocky peninsula, long and wide, between Ellis Fjord and Langnes Fjord in the Vestfold Hills. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (1936–37) and named "Breidneset" (the "broad promontory A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula). Most promontories either are formed from a hard ridge of rock that has resisted the erosive forces that have removed the so ...").

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 ...
