Antarctic lakes


There are hundreds of antarctic lakes, in Antarctica.
In 2018 researchers at the Alfred Wegener Institute's Helmholtz Centre for Polar and Marine Research published a study they claimed cast doubt on the earlier estimate that there were almost 400 subglacial antarctic lakes. 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. 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 2 miles 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.
