Scientists put finger on iceberg rectangle

A GIGANTIC, monolith iceberg was spotted by NASA scientists, as they were being flown over Antarctica during an airborne survey.

The rectangular berg was sighted off the east coast of the Antarctic Peninsula, near the Larsen C ice shelf.

The NASA experts, who believe it might have broken off the shelf recently, say the sharp angles and flat surfaces are evidence that it was a recent break.

The strange, angular shape is known as a “tabular” iceberg, and, said the space agency: “Its sharp angles and flat surface indicate that it probably calved off from the ice shelf.”

NASA scientist Kelly Brunt, who estimated the iceberg to be about a mile wide, told LiveScience: “Tabular icebergs are rather like fingernails that crack off, giving them sharp edges. “What makes this one a bit unusual is that it looks almost like a square.”

The image was taken during an IceBridge flight, which is an airborne survey of the planet’s polar ice. It gives a 3D view of the ice, forming the Arctic and Antarctic, and provides vital information of how it changes over time.
