An Iceberg The Size of Delaware Just Broke In Antarctica

One of the largest icebergs ever recorded broke off from an ice shelf in Antarctica, British scientists announced Wednesday.

Known as A68, the iceberg weighs 1 trillion tons and is twice of the volume of Lake Erie.

Even though scientists first spotted the 120-mile crack in 2011, an ever-lengthening crack in the ice shelf garnered worldwide attention in the last few months. According to Project MIDAS, which has been monitoring the shelf, A68 broke off from the Larsen C ice shelf between Monday and Wednesday.

While the new iceberg won’t change sea levels if it melts, it could pose an immediate threat to boats sailing on the South Atlantic.
