‘Ghost Glaciers’ Protect Greenland’s Landscapes

On August 7, 2013 by Grad Forum

A story by LiveScience published by NBC News features a new study by Lee Corbett, a doctoral student in Dartmouth’s Department of Earth Sciences, that reveals how “ghost glaciers” have protected Greenland’s ancient bedrock landscapes from the island’s ice sheet.

“These ghost glaciers come and go, and leave very little evidence of their presence,” Corbett tells LiveScience. “There are indications that these rocks have been exposed and buried for many Ice Age cycles, (but) when the ice advanced over this area, it was essentially frozen to the bedrock below. It’s not eroding or shaping the landscape,” says Corbett.
