Two new studies offer results that show more warm seawater than previously thought eroding grounding lines, the divider between the glacial ice and where it rests on land and ocean. One of those studies was led by Alexander Robel, assistant professor in the School of Earth and Atmospheric Sciences, whose research team also found that warm seawater may be extending much farther past the grounding lines into the interior of glacial ice sheets. (Coverage of this research also appeared at Daily Kos.)
