What's Going On With That Bizarre Rectangular Iceberg?

A weird iceberg has been spotted by NASA scientists - in the shape of a near-perfect rectangle.

The expansive ice shelves that create the icebergs are hanging off of Antarctic land, somewhat similar to the flimsy tape extended out from a tape measure. These shapes are so ideal that they appear recently carved from a bigger sheet of ice.

Harbeck was a part of a survey to assess the changes in the ice height of glacier draining into Larsen A, B, C embayments. He's a research scientist with NASA's Operation IceBridge, the group that took the stunning photo, and is based at the NASA Goddard Space Flight Center.

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

NASA photographed the odd object in Antarctica last week as part of Operation IceBridge.

The block of ice, with its sharp angles and flat surface, looks more like a man-made structure than a natural phenomenon, but this is because it was "probably recently calved from the ice shelf", NASA ICE said on Twitter.

Son of murdered journalist Khashoggi flees Saudi Arabia for US
US President Donald Trump has stated that it will be up to the US Congress to decide what to do in response to the killing. Turkish officials and some USA lawmakers allege the crown prince ordered the operation in which Jamal Khashoggi killed.

A month from now, however, waves and melting will likely eat away at the iceberg's sharp, right-angled form. But these are just one of two kinds of iceberg classified by shape, called non-tabular icebergs.

The team will continue their work until November 18th, so perhaps we have a few more interesting icebergs to look forward to over the coming weeks.

Not satisfied with blowing our minds once, NASA released an image on Monday showing a second rectangular iceberg.

"There's no one going around with a chain saw and chopping it off. Nature does sometimes go on square angles", he said. "The ice has time to spread out and become perfectly flat", Poinar adds, so when an iceberg breaks off from a large ice shelf along an existing fissure, it looks like a large, flat rectangle.

Scientists are concerned about how ice at Earth's poles will fare with warming temperatures, and how melting ice will affect sea levels around the world, but Bartholomaus is hesitant to draw direct links to climate change.
