Irvine, Calif., Jan. 18, 2017 - University of California, Irvine glaciologists have uncovered large oceanic valleys beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the subsurface troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.
