Now that the close to 2,240 square - mile (5,800 square kilometers) chunk of ice has broken away, the Larsen
C shelf area has shrunk by approximately 10 percent.
The iceberg, which is likely to be named A68, was already floating before it broke away so there is no immediate impact on sea levels, but the calving has left the Larsen
C ice
shelf reduced in
area by more than 12 percent.
