NASA Has Photographed More of Those Strangely Soothing Rectangular Icebergs

NASA Has Photographed More of Those Strangely Soothing Rectangular Icebergs”

Senior support scientist Jeremy Harbeck noticed the iceberg just off the Larsen C ice shelf.

In July 2017, Antarctica's Larsen C ice shelf released the enormous A68 iceberg, which weighs about 1,000 billion tonnes. But how does an iceberg take on such a uniform shape?

The images of the unusually shaped iceberg were captured by Jeremy Harbeck on NASA's Operation IceBridge, an aerial survey of polar ice, when it flew over the northern Antarctic Peninsula on October 16, 2018.

When NASA released a picture of an incredibly strange-looking iceberg that it had photographed during a survey flight over Antarctica I'm not sure they expected the response they received.

As per a statement by Harbeck, he said that at first he thought it was pretty interesting and he often sees the icebergs with the relatively straight edges.

On October 16, NASA scientists found a number of large icebergs between Antarctica's Larsen C ice shelf and the A-68 ice island, which separated from the ice shelf previous year.

Another rectangular iceberg spotted by the IceBridge team.

The new image comes just days after a photo of a perfectly rectangular iceberg found in the northern Antarctic Peninsula was widely shared online.

The new image also shows one corner of Tabular A poking above an engine of Harbeck's plane, as well as the big tabular berg known as A68 off in the distance.

In a different photo (above), Harbeck captured both the edge of the now-famous iceberg, and a slightly less rectangular iceberg.

The photos were taken as part of Operation IceBridge, an ongoing NASA mission to document changes in polar ice. It's now in the midst of a five-week project to chart icebergs in the Northern Antarctic Peninsula, a mission that's scheduled to conclude on November 18.
