Timelapse satellite images of Thwaites Glacier melting

This animation is a series of satellite images acquired over the fast flowing and crevassed ice tongue of Thwaites glacier, by Esa's Sentinel-1 satellite. It runs from 2014 to 2018. It shows a constant stream of small blocky icebergs breaking off the glacier due to the very fractured ice surface. However, in March 2017, a much larger iceberg is seen to break away, drastically reducing the size of the floating ice tongue. The video repeats several times.
