Scientists have finally found Antarctica’s missing groundwater

Vast underground water system helps drive Antarctica’s glaciers

Lake Whillans is a strange body of water, starting with the fact that there is liquid to fill it at all

its temperatures climb to just shy of 0° Celsius, thanks to a combination of geothermal warmth

a geophysicist at Scripps Institution of Oceanography, arrived on the remote stretch of ice above Lake Whillans with a different mystery in mind

Antarctic researchers had long suspected the plumbing below the glacier went much deeper than they could see

A vast reservoir of groundwater reaches more than a kilometer below subglacial water

They expect that similar groundwater systems underpin other areas where the ice is flowing fast—so-called ice streams
