Massive Iceberg Breaks Off Antarctica

(LONDON) — A vast iceberg with twice the volume of Lake Erie has broken off from a key floating ice shelf in Antarctica, scientists said Wednesday.

The iceberg broke off from the Larsen C ice shelf, scientists at the University of Swansea in Britain said. The iceberg is described as weighing 1 trillion tons (1.12 trillion U.S. tons).

The process, known as calving, occurred in the last few days, when a 5,800-square-kilometer (2,240-square-mile) section broke away.
