Four years-worth of satellite data shows three calving events in Pine Island Glacier on the West Antarctic Ice Sheet, the most recent of which took place at the weekend.
A calving event describes the process of a block of ice separating from a glacier and drifting out into the ocean. It can take place on different timescales. In some instances, it can take decades. In others, calving events can be frequent and occur in quick succession.
The most recent of the three calving events in the animation took place Tuesday, when a large chunk of the Pine Island Glacier shattered, forming a 120 square mile iceberg. An animation from the ESA shows just how rapidly cracks were able to grow and cause the breakaway. The clip uses 57 images taken between February 2019 and February 2020 by Copernicus Sentinel-1., scientists have been anticipating the breakaway for almost a year, after satellite images revealed large cracks in the glacier were spreading and becoming bigger. The iceberg that formed was almost the size of Las Vegas.Calving events at the Pine Island Glacier appear to be increasing in frequency.
With iceberg B-49 the Pine Island ice shelf has again become smaller than we have observed in recent history.
