WASHINGTON — A giant ice island broke off the Petermann Glacier in northern Greenland according to a report Friday.
A University of Delaware researcher said the floating ice sheet covers 100 square miles (260 sq. kilometers) — more than four times the size of New York's Manhattan Island.
Andreas Muenchow, who is studying the Nares Strait between Greenland and Canada, said the ice sheet broke off early Thursday. He said the new ice island was discovered by Trudy Wohlleben of the Canadian Ice Service.
