Another large iceberg broke away from Antarctica
Satellite imagery showed the birth of another large iceberg with an area of over 250 square kilometers. An array of ice broke from the glacier bistratose pine island. Photos from the satellite Sentinel-1 has published a Twitter employee Delft University of technology Stef Lermitt.
Reduction of the glacier pine island is a quarter of all loss of ice of Antarctica and is approximately equal to 45 billion tons per year. Received on 23 and 24 September satellite images show the appearance of open water between the ice shelf glacier and iceberg. A new array of floating ice, however, did not go to any comparison with an iceberg, calved from the glacier recently, Larsen C, the area of which amounted to about 5.8 million km2. For glacier pine island, which is responsible for 10% of the West Antarctic ice sheet, this is the third large iceberg in four years: in 2013 it spawned floating ice with an area of 652 km2, and in 2015 — 582 km2.

The office also confirmed the data from the satellites MODIS and Landsat 8. While an iceberg seems unstable, it split into smaller pieces of ice. Christopher Schumann from the Laboratory of the Sciences of the cryosphere NASA, told Gizmodo that it is not in size but in the General trend.
