Researchers from England have discovered gigantic subglacial tunnels in Antarctica.
The height of the canals over 100 kilometers long is 250 meters. Geologists were able to identify them under a kilometer-long layer of ice using radar scanning. For details, see the researchers' article published in the journal Nature Geoscience. The discovery was made thanks to the study of satellite photography data, as well as radar scanning of the surveyed area. In the images taken from orbit, scientists noticed the channels of the channels with the naked eye, despite the huge layer of ice that covers them. Radar scans, carried out by aircraft specialists, helped to identify voids in the same places, the height of which reaches 250 meters, and the data on the channels on land matched the data on the channels located under the ice shelf. The tunnels found, according to the researchers, end in a placewhere the continental glacier gradually merges into the shelf, and where long indentations in the ocean floor originate. Scientists are currently paying close attention to flows under ice shelves due to the fact that they play a key role in ice melting. The authors of the discovery emphasize a change in the understanding of scientists about the real structure of the glaciers of Antarctica. The ice shelf was previously thought to be floating on a relatively thin layer of water, but new information suggests that the water under the ice is not just a dormant layer. It would be more accurate to consider it as an active environment, washing its channels and tunnels, as ordinary rivers do.
