Nobody knows why the Antarctic icebergs of a trillion tons make a complete fall

One of the largest icebergs ever recorded, weighing more than a thousand billion tons broken on the Larsen ice floe last July. The iceberg, called A68, is massive, it covers an area of ​​5,000 km2 and is about 350 meters thick. It's bigger than most cities in the world. This gigantic piece of ice has now returned to Antarctica and is about to crush on the ice floe from where it came.

The iceberg was so massive that he spent most of the year just stuck in the mud, in the seabed, reports Earther. Now, in the middle of winter in this part of the world, the iceberg has made its biggest move since its fall in the water. He made a dramatic counter-clockwise turn and headed towards the Larsen C shelf for a big crash.

According to ProjectMIDAS, an Antarctic research group, the A68 is the sixth largest iceberg ever recorded. Last year, as it broke down and fell into the ocean, the whole world watched with some magnitude, taking every little information on the shelf along the way. After the actual break and images of its release, the iceberg quickly found itself stuck on the bottom of the ocean in an area called the Bawden Ice Rise, a shallow part of the sea where a shepherd of this size found himself unable to move.

Around July of this year, a year later, the iceberg started to move. It has not been easily seen that this part of the world stays in the dark in winter. A68 had begun drifting north, the report notes. Mark Brandon, a polar oceanographer, spotted this action using satellite temperature data from the Suomi nuclear power plant.

The data was then processed into false color images. Here, the warmer regions like seawater are brilliant compared to cooler icy surfaces like on glaciers and icebergs. The images show that A68 rotates counterclockwise in July and late August, it rotates 90 degrees, placing itself perpendicular to the tablet.

Regarding the displacement of the A68, the report mentions that no one knows for the moment. One of the reasons why glaciologists are uncertain about this move is that the seabed of this region is not yet clearly mapped. It is therefore impossible to predict what will happen now.
