Sentinel-1A Satellite Catches Jakobshavn Glacier Shedding Ice

Jakobshavn glacier, also known as Sermeq Kujalleq and the Jakobshavn Isbræ, is a large glacier in West Greenland and is among the world’s most dynamic glaciers. Radar images from ESA’s Sentinel-1A captured the glacier before and after a massive calving event, which took place between 14 and 16 August 2015. The image composite includes different Sentinel-1A images from 27 July, and 13 and 19 August. The red, green and blue indicate the position of the calving front and other dynamic features on each respective date. Image credit: Copernicus Sentinel data /ESA.
