Near-perfect rectangular iceberg found in Antarctica

Near-perfect rectangular iceberg found in Antarctica

Scientists explained that the iceberg in the photo was a tabular iceberg - a large slab of ice with a flat top and vertical sides which form by calving (splitting) from a larger ice shelf.

It looks so flawless that it seems Photoshopped - but a unusual perfectly rectangular iceberg near Antarctica is a natural phenomenon, NASA scientists say. 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. This berg hasn't been measured yet, but Brunt says it's about one mile across, which isn't not particularly large.

The striking iceberg isn't the only perfectly shaped formation scientists came across on their flight over the Atlantic last week, with NASA also sharing images online of a triangular berg found in the Weddell Sea.

Operation IceBridge is on a mission to measure and monitor polar ice and document changes over time. "It probably wouldn't flip over", she said, but it could still crack and break up.

Well here's something you don't see everyday: an iceberg so unbelievably geometric in shape you'd think it was deliberately carved with a huge chainsaw.


According to the National Snow & Ice Data Center, ice shelves are permanent floating sheets of ice that connect to a land mass.

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

The space agency said: 'A tabular iceberg can be seen on the right, floating among sea ice just off the Larsen C ice shelf.

Its precisely cut corners show that it hasn't been around that long, because the sharp edges would become round from exposure to wind and waves.
