The lakes are fed by geothermal heat that seeps up from the Earth's interior, melting away the bottom of the ice sheet at a rate of several dime - thicknesses per year and liberating water from the ice.
They are linked by rivers that form when melting ice expands the lakes, increasing pressure under the ice cap and causing underground channels of water and mud to squirt out.

A new study by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.
The heat from those eruptions would have melted massive amounts of ice to form englacial lakes — bodies of water that form within glaciers like liquid bubbles in a half - frozen ice cube.

«The DIC lakes are situated within bedrock troughs in mountainous terrain, exist at temperatures well below the pressure - melting point, do not receive surface meltwater input, and likely consist of hypersaline water derived from dissolution of a surrounding salt - bearing geological formation,» the researchers reported.
These lakes occur as a result of geothermal heat trapped by the thick ice, melting it from underneath, and the great pressure from the ice above, which lowers the melting point of water.
I know that, such as East Antarctica, which ice sheet's thickness could reach several kilometers therefore huge pressure and geothermal flux results in melting, then the subglacial lakes and water channels.
Mysterious under - snow lakes pockmarking its edges and deep layers of ice at higher elevations both point to changes that could hasten melt and send water cascading into the ocean, pushing global sea levels ever higher.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.
