Huge crack in Antarctic ice shelf grows by 6 more miles

Huge crack in Antarctic ice shelf grows by 6 more miles

This Nov. 10, 2016, aerial photo released by NASA, shows a rift in the Antarctic Peninsula's Larsen C ice shelf.

A crack in an ice shelf in Antarctica grew by six miles in the past few weeks, British scientists say, and now measures more than 100 miles long.

Once the crack is complete, a giant iceberg larger than Rhode Island will break or "calve" off of Antarctica. The iceberg would be one of the biggest on record.

The break "will fundamentally change the landscape of the Antarctic Peninsula," according to Project MIDAS, a British Antarctic research project that's tracking the crack.

Only a final 12 miles of ice now connects the future iceberg to its parent ice shelf.

Ice shelves are permanent floating sheets of ice that connect to a land mass, according to the National Snow and Ice Data Center.
