The largest ice shelf in the Arctic is located in northeastern Greenland. It has now broken off and appears to be rapidly shrinking, according to KNR.
An ice shelf is a large mass of ice that is attached to a glacier, yet floating on the sea.
The ice shelf that has now broken off is located near a glacier called the Niogenhalvfjerdsfjorden Glacier. Since 1999, the ice shelf has diminished more than 160 square kilometers, more than twice the size of Manhattan.
