Description

Satellite image of an ice shelf (diagonally across bottom left) in the East Antarctic in January 2022. The ice shelf is fed by the Conger (left) and Glenzer (upper left) glaciers and floats on the Mawson Sea. The ice shelf is also anchored to Bowman Island (centre right). This ice shelf, which measured around 1, 200 square kilometres, collapsed in March 2022. It had been slowly shrinking since the mid-2000s, but in early March 2022 an iceberg measuring 144 square kilometres calved from the ice sheet. Temperatures of 40 degrees Celsius above normal in mid March lead to a second iceberg calving and then the disintegration of the ice sheet. Image data obtained on 9th January 2022 by the Operational Land Imager (OLI) on Landsat 8. For an image of the ice sheet after collapse see C055/3346.
