Subglacial lake
Videos
A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where liquid water c

Lake Vostok is the largest of Antarctica's 675 known subglacial lakes and the 16th largest lake in the world by area. Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Stati

…melting point of water intersects with the temperature gradient. Very thick ice gives rise to a relatively high temperature at the bottom. For example, Lake Vostok, the largest Antarctic subglacial lake, is located in a basin and is covered by ice nearly 4000 metres thick, much thicker than the ice sheet around…
