A photo from open sources researchers from England found in Antarctica ice tunnels of gigantic proportions. Channel height more than 100 kilometers long is 250 meters. Geologists managed to identify them under a kilometer-long layer of ice using radar scan.
Details presented in an article by researchers published in a journal Nature Geoscience. The discovery was made through the study of data satellite photography, as well as radar scanning terrain. In the pictures taken from the orbit, channel channels scientists noticed with the naked eye despite the huge layer of ice the thickness that covers them. Radar scan that was carried out by specialists from aircraft, helped to identify in the same places of emptiness, the height of which reaches 250 meters, and data on channels on land corresponded to data on channels located under ice shelf. Photos from open sources Tunnels found, according to researchers end at the place where the mainland glacier gradually goes offshore, and where long dredging on the ocean floor. Close attention to flows under ice shelves, scientists are currently paying in connection with by the fact that they play a key role in melting ice. The authors discoveries emphasize a shift in scientists’ understanding of real structure glaciers of Antarctica. Ice Shelf Used to Be Floating Over a relatively thin layer of water, the new information also testifies that the water under the ice is not at all just inactive interlayer. It would be more accurate to consider it as an active medium, washing its own channels and tunnels, as ordinary rivers do.
