Iceberg was previously part of the largest segment of the Larsen Shelf Glacier – Larsen C. It is in the west of the sea Weddell. Giant fragment of the glacier weighs more than a trillion tons, its area – about 5800 km2. This is one of the largest icebergs in the history of observations. Specialists of the British Research Project Midas reported.

Ice block finally separated from the glacier in the interval between July 10 and 12, 2017. Destruction recorded one of NASA AQUA research satellite devices – Modis spectroradiometer. His data then confirmed the pictures of the meteorological satellite Suomi NPP.

Scientists have long expected the separation of this fragment of the glacier. In December 2016, the length of a giant crack in the Larsen C segment exceeded 100 km, and the depth – 500 m. Then Midas experts predicted that the Square of the Giant Iceberg would make about 6,500 km2. As a result, it turned out to be somewhat less than expected, and reduced the area of ​​the Larsen segment with 12%. Representatives of the Midas project believe that the new structure of the glacier will be less stable, and after a few years or decades of Larsen C can continue to collapse. Perhaps the new Iceberg himself will always be as long as. Scientists predict that part of his future fragments can go to the north, in warmer water.

Researchers do not associate the Iceberg Department with anthropogenic exposure to the climate. However, after the loss of a large fragment, the Larsen glacier became more vulnerable, so in the coming years is needed intensive observations of this territory.

The Shelf Glacier Larsna, Located At The Coast of Antarctica, Began to Actively Collapse in The Second Half of the Twentieth Century. Before That, He Remained Stable for 10 Thousand Years. Segment Larsen and Collapsed in 1995, Larsen B – In 2002.

MOST Likely, The New Iceberg Will Receive The Name A68. The Names of The National Icebergham Antarctic Gives The National Center Of The United States on The Control of Glaciers (National Ice Center), Which Conducts A Significant Part Of The Observations of the State of Glaciers. The Letter In The Title Means The Longitude, on Which The Iceberg Was First Discovered. The Letter A IS Assigned to All the Fragments of Glaciers Fixed in the Gap from 0 ° To 90 ° West Longitude.
