Caption: Series of satellite images showing the formation of the large iceberg, known as A-68, that eventually broke off of the Larsen C ice shelf in the Weddell Sea, Antarctica, in July 2017. The iceberg has an area of around 6,000 square kilometres, more than 10 per cent of the area of the ice shelf. As ice shelves float, the calving of the iceberg will not lead to immediate changes in sea level. However, the presence of an ice shelf slows the seaward flow of glaciers and ice streams. Loss of part of the ice shelf could lead to increased flow that could raise sea levels. Images obtained by the Thermal Infrared Sensor (TIRS) on the Landsat 8 satellite between the 14th and 21st July 2017.
