Dozens of lakes discovered deep under colossal ice sheet

A new survey of the Greenland Ice Sheet has revealed dozens of previously unknown lakes lying beneath the massive body of ice.

The 56 lakes, ranging in size from about 650 feet to more than 3.5 miles, bring the number of lakes known to exist under the sheet to 60. The researchers say it’s the first comprehensive look at bodies of water locked under the sheet, which in recent years has been melting rapidly as a result of global warming.

“We found a lot more lakes than what people have thought before,” said Winnie Chu, a postdoctoral researcher at Stanford University in Palo Alto, California, and coauthor of a paper about the research published June 26 in the journal Nature Communications.
