"What makes it unusual is that it looks almost like a square," explained Kelly Brunt of the University of Maryland.

NASA (National Administration of Aeronautics and Space) has discovered a perfectly rectangular ice block on the Larsen ice barrier, a platform located on the east coast of the Antarctic Peninsula.
Thanks to the "Operation IceBridge" project, which is currently being developed to explain the link between global warming and polar regions, NASA has photographed this huge icecap that exceeds one kilometer.
The aviation agency has published in the Twitter account of the project the picture of this phenomenon.
In the tweet, it is explained that the ice cap is a tabular iceberg, a type of glacier that forms exact geometric shapes.

"Since yesterday's flight #IceBridge: a tabular iceberg floats on ice, on the Larsen C platform. The sharp angles and flat surface of the iceberg indicate that it is safe." Probably recently detached from the pack ice, "he said. the publication
In the Live Science Web publication, Kelly Brunt, a scientist at the University of Maryland, said that, as in all icebergs, the visible part only accounts for 10% of its total mass.
"What makes it unusual is that it almost looks like a square"he remarked. He also said that the iceberg seems to have been created recently since neither the wind nor the waves have changed its angles.
