April 2 (UPI) -- The grounding lines of Antarctica are on the retreat on the ocean floor. According to a new study by scientists at the University of Leeds, warm ocean water is shrinking Antarctica's underwater footprint.According to the new data, published this week in the journal Nature Geoscience, the Southern Ocean melted 565 square miles of underwater ice between 2010 and 2016.Antarctica's glaciers have been retreating at an average rate of 82 feet per year. But the rate retreat of the grounding lines of eight of the ice sheet's 65 largest glaciers is five times greater, roughly 410 feet per year.The most dramatic rates of grounding line retreat were measured along the coast of West Antarctica."Our study provides clear evidence that retreat is happening across the ice sheet due to oce...
