Monolithic rectangular iceberg photographed by Nasa

The iceberg is believed to have broken off from the Larsen C ice shelf, where a giant iceberg the size of DE calved previous year.

NASA scientists spotted this iceberg in Antarctica on October 16 as part of the Operation IceBridge program - an ongoing mission to monitor polar regions and track the planet's global climate system.

In the case of tabular icebergs, she said, that subsurface mass is usually regular-looking and geometric, similar to what's visible above.

The picture was taken last week by scientists on a Nasa research plane.

Speaking with Live Science, NASA ice scientist Kelly Brunt said the shapes of the icebergs are formed by a fairly common process.

The US space agency said the object's sharp angles and flat surface suggested it had recently broken away from an ice shelf.

A photo shows a thick block of ice up to a mile long dramatically protruding from a sea of thin frozen water, thought to have recently splintered off.

Unlike the icebergs of non-tabular variety, such as the irregularly shaped berg that sunk the Titanic, these chunks of ice are distinguished by their flat tops, steep sides, and sometimes massive sizes.

"You can see at between 7-12 July 2018 the weather conditions and ocean currents conspire to swing the trillion tonnes of the giant iceberg A68 in an anticlockwise direction", he said.

"What makes this one a bit unusual is that it looks nearly like a square", she said.

"We get two types of icebergs: We get the type that everyone can envision in their head that sank the Titanic, and they look like prisms or triangles at the surface and you know they have a insane subsurface", Brunt said.

And then there's the iceberg photographed last week by NASA's Operation IceBridge team.
