Coincidence and Twitter lead to discovery new crack in Greenland’s largest glacier

19 April 2017 by Webredactie CiTG

Something caught the eye of Stef Lhermitte last week, while he was looking through satellite images of the Greenland’s Petermann Glacier. Almost by coincidence he saw a new thin line, as he was going through ESA Sentinel-1 images for research on melt. He checked other satellite images, and saw the line first appear on July 2016, apparently unnoticed until then. In a series of five tweets, Lhermitte shared his discovery, hoping someone might be able to shed some light.
