Giant crack splitting Antarctic ice shelf

A huge crack in one of Antarctica’s biggest ice shelves is widening at the rate of three feet per day. It could create an iceberg as big as the state of Delaware.

The giant crack in Antarctica’s fourth-largest ice shelf, Larsen-C, was first observed in 2014. The crack is not getting any longer; it is however getting wider every day.

According to Dan McGrath, a geophysicist with the U.S. Geological Survey, the crack is heading for the ocean edge.

Eventually about ten percent of the ice sheet could break off.
