Antarctic lakes

There are hundreds of antarctic lakes, in Antarctica.[1][2][3][4][5][6] In 2018 researchers at the Alfred Wegener Institute's Helmholtz Centre for Polar and Marine Research published a study they claimed cast doubt on earlier estimate that there were almost 400 subglacial antarctic lakes.[7] Antarctica also has some relatively small regions that are clear of ice and snow, and there are some surface lakes in these regions. They called for on the ground seismic studies, or drilling, to determine a more reliable number.

These lakes are buried beneath deep layers of glacial ice.[1][2][3] When a glacier is very thick, the pressure at the bottom is great enough that liquid water can exist at temperatures where water would freeze, at regular pressures. The ice above Lake Vostok, the largest antarctic lake, is approximately 4 kilometres thick.

Scientists studying the lakes, by careful drilling and water sampling, suggest conditions there may resemble the oceans believed to exist on planet Jupiter's moon Europa.[2][3]

Selected Antarctic lakesEdit

Selected Antarctic lakes
name surface
depth volume below
Ablation Lake 117 metres
(384 feet)+
500 metres
(1,600 feet)
The lake contains both saline and freshwater layers.[8][9]
Algae Lake An ice-free lake in the ice-free Bunker Hills highlands.
Amphitheatre Lake A surface lake.
Beaver Lake A surface lake, near a "stagnant" glacier, its name derives from the STOL Beaver aircraft used to supply a nearby base, not from the presence of actual beavers.
Lake Boeckella A surface lake, named for the crustaceans from the genus Boeckella it hosts.
Lake Burton 1.35 square kilometres
(0.52 square miles)
9,690,000 cubic metres

A meromictic and saline lagoon.
Changing Lake One of three surface lakes on Signy Island.
Concordia Lake 900 square kilometres
(350 square miles)

A large subglacial lake, discovered in 1999.[10]
In 2009 it was the second largest subglacial lake to be studied.[11]
Lake Ellsworth
Forlidas Pond This small pond is the only pond in the northern Pensacola Mountains.[12]

Over the past 40 years, radar imagery has revealed around 150 freshwater lakes of various sizes and ages beneath the massive Antarctic ice sheet. Some have been isolated from the outside world for millions of years, raising the possibility that they hold unique life forms. The dark, nutrient-deprived environment of the lakes could resemble conditions on Jupiter's moon Europa, which is assumed to hold a large ocean beneath its frozen surface.

Nearly 4,000 species of microbes inhabit Lake Whillans, which lies beneath 2,625 feet (800 meters) of ice in West Antarctica, researchers report today (Aug. 20) in the journal Nature. These are the first organisms ever retrieved from a subglacial Antarctic lake.

However, when it comes to large lakes -- they had expected to find ones as large as Lake Constance -- the scientists came up empty-handed, even though they analysed the radar data for every known lake criterion.

Two of the lakes are unusual in that they are in contact with seawater from George VI Sound which is covered by an ice shelf, 100-500 m thick, and which separates Alexander Island from the Antarctic mainland.
