NASA discovers two lakes under the layer of ice in Antarctica, part of a mysterious network of water

NASA scientists have found two new lakes under the icy layer in Antarctica. These lakes are part of a network of 1.2 to 2.5 miles beneath the ice. These lakes are said to fill and empty continuously. Because of this, the movement of layers is also affected and also on how water gets into the Southern Ocean. This is an important process of circulation in the world’s oceans.

According to Professor Matthew Seyfried, a geophysicist at the Colorado School of Mines and the author of the study, it is not just the ice layer here but the water system that is connected to the Earth’s system. This system under ice was first discovered in 2003 by NASA’s ICESat mission. The data analysis found that the increase in ice in West Antarctica reveals the mass of water beneath the icy layer.

Earlier it was believed that such lakes flow separately and are not connected with others. Later in 2007, researchers found that changes in the height of the ice on the surface of Antarctica reflect the waters of the lakes below. They empty and then fill up several times before flowing into the Southern Ocean. After the ICESat mission, ICESat-2 helps to understand this network better.

Earlier in the second study, scientists have warned that every year 53 thousand square km of ice is melting from the earth. Due to this, humans may have to face serious consequences in the coming time. He said that between 1979 and 2016, so much ice has melted that it can fill the huge Superior Lake.
