Antarctic lakes deep beneath the ice could be teeming with microbial life

Frigid lakes locked under the Antarctic ice sheet may be home to microbiological life than scientists ever imagined.

More than 400 subglacial lakes lies below Antarctica ice cover, completely closed from sunlight, according to a new paper published Feb. 17 in the magazine Scientific progress. These lakes form where the weight of the surface ice drops to the bottom of the sheet, creating intense pressure and lowering the melting point of the ice. As the base melts, the remaining ice insulates the melt water from the cold air, while the geothermal heat from the bottom substrate also helps prevent freezing, according to the statement.
