This photo is taken by the infrared camera TIRS installed on the satellite Landsat 8. It shows a recently broken off from the Larsen supercoil glacier with an area of 6000 square kilometers broken off two weeks ago from the ice shelf Larsen S.
The current gradually carries a giant iceberg to the north of the Larsen glacier. The satellite image shows that smaller pieces of ice have already begun to chip away from the iceberg.
Iceberg of this size will gradually melt, raising the level of the ocean, splitting into pieces and threatening navigation.
