"Vast Iceberg Poised To Crack Off Antarctica: Scientists"

"A vast iceberg, expected to be one of the biggest ever recorded with an area almost the size of the U.S. state of Delaware or the Caribbean island state of Trinidad and Tobago, is poised to break off Antarctica.

A rift, slowly developing across the Larsen C ice shelf on the Antarctic Peninsula in recent years, expanded abruptly last month, growing by about 18 km (11 miles). It is now more than 80 km long with just 20 km left before it snaps, scientists said.

"The Larsen C Ice shelf in Antarctica is primed to shed an area of more than 5,000 square km (1,930 square miles) following further substantial rift growth," scientists at Project Midas at the University of Swansea in Wales said in a statement."
