In the ot of Iceberg A-76, which is considered the largest in the world, there is nothing unusual from Antarctica, such events happen every year. The chief specialist of the Department of Sciences of the Russian Academy of Sciences, doctor of geographic sciences Nina Zaitseva, told about it in a conversation with “Tape.ru”.
“Every glacier under the strength of the gravity of ice moves. Antarctica, in principle, is the dome. Therefore, ice flows off. Absolutely nothing extraordinary. In my memory, not one gigantic iceberg was filming,” she said.
According to Zaitseva, the glaciers are formed in those areas where the sum of negative temperatures exceeds the amount of positive. She explained that in Antarctica there is a certain relief that raised over the sea level, snow is dropping there.
“in the glacier ice under great pressure at great depth flows, it becomes not fragile, and viscous. This is a completely normal phenomenon. All glaciers from the mountains go down. Somewhere there will be a disturbance of the relief – a crack is formed, so Outside. Here is the same. The ice that falls into the water, he first, begins to emerge, which is already a certain tension, and secondly, somewhere there is such a critical moment when the weight of that piece, which is already in water, Big enough, “the doctor of geographic science explained.
The climatologist noted that this sloped iceberg, like others, can be a threat only to ships that will swim nearby.
Earlier it was reported that the dimensions of the sloping of giant ice floes are 170 kilometers in length and 25 kilometers wide, and its area reaches 4320 square kilometers, which is comparable to the territories of the Spanish Island Mallorca.
A-76 Own from the western side of the Filter Shelf Glacier – Ronne in the sea Weddell. Iceberg was identified by the British Antarctic Service and confirmed by the US National Ice Center using the Copernicus SentineL-1 mission images.
