An iceberg that was once the size of Rhode Island and the biggest in the world has lost about 80% of its mass since May, scientists at the British Antarctic Survey (BAS) report.
Known as A23a, the "megaberg" has been rapidly disintegrating since becoming trapped in a current flowing counterclockwise around South Georgia Island in the South Atlantic Ocean, Andrew Meijers, a polar oceanographer with the BAS, told CNN.
