Tracking a Crack in the Antarctic Ice Sheet
Scientists have been closely following the growth of a large crack in the Larsen C ice shelf on the Antarctic Peninsula. From late 2016 until now, the crack has grown about 150 km long, accelerating in late June 2017. In these dark months, the most recent observations have been done by Thermal Infrared Sensor (TIRS) on Landsat 8. If the crack reaches the coast, which is just about 13 km away, the ice will begin to calve and could be the largest iceberg ever recorded.
