NASA’s Cryospheric Sciences Program released this astonishing aerial photo of a rectangular iceberg in Antarctica. Located on the Larsen C ice shelf, the curious iceberg is likely one mile or so across. From the BBC News:
Such objects are not unknown, however, and even have a name – tabular icebergs.
These are flat and long and form by splitting away from the edges of ice shelves.
Kelly Brunt, a glaciologist with Nasa and the University of Maryland, said the process of formation was a bit like a fingernail growing too long and cracking off at the end.
They were often geometrically-shaped as a result, she said.
"What makes this one a bit unusual is that it looks almost like a square," she added.
