Two Subglacial Lakes Discovered in Greenland
This map shows the location of two subglacial lakes near the town of Qaanaaq in northwestern Greenland.
Subglacial lakes are likely to influence the flow of the ice sheet, impacting global sea level change. The discovery of the lakes in Greenland will help researchers to understand how the ice will respond to changing environmental conditions.
The Cambridge scientists used airborne radar measurements to reveal the lakes underneath the ice sheet.
The two lakes are roughly 8-10 km2, and at one point may have been up to 3 times larger than their current size.
They are found in the northwest sector of the Greenland Ice Sheet, about 40 km from the ice margin, and below 757 and 809 m of ice, respectively.
â€œOur results show that subglacial lakes exist in Greenland, and that they form an important part of the ice sheetâ€™s plumbing system.

Scientists have discovered two subglacial lakes 800 meters below the Greenland Ice Sheet. Subglacial lakes are likely to influence the flow of the ice sheet, impacting global sea level change. The discovery of the lakes in Greenland will also help researchers to understand how the ice will respond to changing environmental conditions.
