The world's largest ice lake in the world

Researchers have discovered for the first time lakes located beneath ice shelves in Greenland, the world's largest island.

Polar Scott Research Institute (SPRI) scientists, at the University of Cambridge, UK, discovered two lakes located beneath the ice shelf in Greenland, at a depth of 800m.

According to Nature World News, the area of ​​the two lakes under the ice is discovered about 8-10 km ² , but they can be three times larger than the present at certain times.

The finding suggests that this finding will help them understand how the Greenland ice sheets react with the changing weather conditions, such as how lakes under the ice can affect the flow of ice sheets and sea ​​level change.

"The results of our study show that sub-ice lakes exist in Greenland and they have an important role for the aquifer system under the ice sheets. Speed ​​as well as the way water moves side by side. Under the influence of iceberg speed, a closer understanding of these lakes could allow us to predict the reaction of ice sheets to a more precise global warming , " Steven Palmer , the research leader said.

The structure of the lakes below the Greenland ice shelf differs from the similar lakes discovered beneath the Antarctic ice sheet. The researchers suspect that, unlike in Antarctica, where surface temperatures are always below freezing, Greenland lakes can be replenished by the melting of surface water through cracks. ice.

Another hypothesis was suggested that lakes on the surface near this area could feed the lakes under ice, in warmer months.

So far, scientists have discovered more than 400 lakes of ice below the Antarctic ice shelf. However, this is the first time that ice-bottom lakes have been found beneath the ice shelf in Greenland, the island of Denmark. This may be because the ice surface in this area is relatively steep.
