This is the first discovery of such a sub-glacial formation on the planet, reports Phys.org.

Researchers have mapped the lake bottom by analyzing data from instruments that can read signals through the ice. Most of the data came from aircraft flying at low altitude above the ice cover as part of the NASA IceBridge mission.

The prehistoric lake was about 7.1 thousand square meters. km. The deposits in the knife-like basin are 1.2 km thick. The images show the network of 18 creek beds that fed the lake. Experts calculated that the water depth in this reservoir was from 50 to 250 m.

The bottom of the lake can be hundreds of thousands and even millions of years old and contain unique fossils, as well as information about the climate and life in the distant past. The discovery will help understand what awaits Greenland as it warms.
The ice sheet, which is now melting at an accelerated rate, contains enough water to raise sea levels by 7.3 m.
