Giant Antarctic iceberg snaps into the ocean after forming ominous crack

Crack.

After a nearly 20-mile rift formed across Antarctica’s retreating Pine Island glacier in late September, about 115 square miles of ice — an area more than five times the size of Manhattan — has now broken off into the sea.

The single largest chunk of ice is four times the size of Manhattan.

This iceberg calving event reinforces a continuing story of the melting and retreat of Antarctic glaciers, particularly due to relatively warm oceans eating away at the ice from below.
