While the study focused on one tidewater glacier, the new approach should be useful to researchers who study melting at other tidewater glaciers around the world, which would help to improve projections of global sea level rise.
The expedition, meanwhile, took the Indian team 99 days instead of the usual 60 days or so. Their ship was anchored near Bharati Maitri station, as the ice sheet had become thicker after the blizzard and ship didn’t have the capacity to break it and make its way through.
The pace of melting rose dramatically over the four-decade period. From 1979 to 2001, it was an average of 48 gigatonnes annually per decade. The rate jumped 280 per cent to 134 gigatonnes for 2001 to 2017.
During Antarctica's summer, scientists from University of Wisconsin - Milwaukee (UWM) climbed the McIntyre Promontory's frozen slopes in the Transantarctic Mountains, and found evidence of these ancient fossils.
The March mission was part of NASA’s Oceans Melting Greenland (OMG) project, a five-year, $30 million effort aimed at improving sea level rise projections by understanding how warming oceans are melting ice sheets from below - the most ambitious research on the subject to date
