It looks like a quick photoshop job. Or the work of a secret Antarctic civilization that worshiped right angles. But this rectangular iceberg is natural to one hundred percent.
So it's not a perfect rectangle, but this floating ice cap is approaching disturbingly. NASA scientists spotted the geometric beauty off the northern Antarctic Peninsula when he investigated the area earlier this month as part of Operation IceBridge, the oldest initiative in the polar ice.
"I thought it was quite interesting, I often see icebergs with relatively straight edges, but I've never seen it before with two as straight angles as this one," said the scientist. IceBridge Jeremy Harbeck in a statement from NASA.
With its steep flanks and flat top, this iceberg is what is known as a tabular iceberg. NASA has not released the official measurements, but Ted Scambos, senior researcher at the University of Colorado, told Boulder National Geographic He estimates that the slab has a height of 130 feet and a mile wide or more.
The satisfactory acute angles and the flat surface probably mean that the rectangle has been calved from the Larsen C ice sheet quite recently. NASA tweeted. Larsen C is a 20,000 square mile floating ice layer anchored in the Antarctic landmass. In the background of some images taken by Harbeck, you can distinguish the famous Delaware iceberg that detached from Larsen C in July 2017.
Although it looks pretty, this iceberg has a dark side. Experts worry that the big iceberg is another sign of how rising global temperatures are threatening the future of the pack ice. Because this ice rests on the mainland, when it breaks or melts in the ocean, it adds more water, gradually raising the sea level.
