Mother Nature with a chainsaw? Perfectly rectangular iceberg dazzles online

Nasa had found a piece of floating ice in Antarctica that is so flawless, it looks like it was deliberately cut.

Nasa has released a striking photo of a rectangular iceberg floating in the Weddell Sea off Antarctica.

They're usually formed when breaking off from ice shelves; in this case, it likely came from the deteriorating Larsen C-the same shelf that saw a 2,200 square-mile, trillion-ton iceberg break away previous year.

Scientists are now taking part in an airborne survey of Earth's ice as part of what is known as Operation IceBridge.

As the picture shows, tabular icebergs are large slabs of ice with almost vertical sides and flat tops.

Operation IceBridge's mission is to image the planet's polar regions to better understand how ice has changed and shifted in recent years.


Many of thelargest icebergs on record have formed this way.

A triangular iceberg was also seen nearby, surrounded by several different types of sea ice. "It probably wouldn't flip over", she said, but it could still crack and break up.

Brandon wrote on his blog that in July, 'the weather conditions and ocean currents conspire to swing the trillion tonnes of the giant iceberg A68 in an anticlockwise direction.

As the sea and wind haven't eroded the iceberg's clean edges, it's thought that it must have cleaved away only recently.

'My guess is that A68a will continue rotating as it is now around that western point, until what is currently the northern edge collides with the Larsen C ice front. I should think we will see some interesting collisions with the ice shelf in the next few months'.

The calving of the huge iceberg reduced the size of the ice shelf by 12%. Once they split from an ice shelf, they are often geometric in shape.
