“This one island may maintain a number of clues,” College of Virginia in Charlottesville glacial geologist Lauren Simkins informed Nature Information. “Fast rebound may enhance stress on the remaining ice sheet, inflicting it to interrupt aside extra rapidly.”
Researchers need higher perceive the island and the way it got here to be uncovered by the point their journey finishes on the finish of March.
“However a rising continental shelf may additionally anchor glaciers, rising their stability and slowing their march to the ocean,” Simkins added.
