NASA flies and photographs regularly around Antarctica to study changes in the istketc.
During such an overview On October 16, researcher Jeremy Harbeck discovered something unusual.
In his eyes, he noticed a strange-shaped ice structure, located just outside the huge Larsen C ice shelf, which extends to the Antarctic Peninsula.
Shelfisarna are the seabed in relation to the Antarctic continent. From time to time, they calve, that is, emit fragments that float like icebergs.
The iceberg often has straight edges and even, and the top is equal. They are thus broken because of the structure of the ice crystals and the way in which the material they form, the ice and the packed snow, behaves so when it is subjected to constraints, "explains NASA researchers for CNN.
But this ice cream was unusually regular.
"I've already seen an iceberg before, but never one with two right corners," Harbeck said in a statement.
Isberget seemed to have been cut with a huge cutting tool, like a leaf saw of a kind of giant.
– It was really interesting visually. The sharp edges and flat surface indicate that the plateau has recently calmed down.
Immediately next to the spectacular iceberg, there was another with a strangely regular shape. It was properly rectangular overall (the first had a short edge), but the edges were not as sharp.
The main focus of Harbeck during the flight mission studies the gigantic A68 iceberg (twice the size of Gotland), which separated from Larsen C last year.
