Petermann Glacier, a major outlet glacier of Northern Greenland, drains a marine-based basin vulnerable to destabilization. Using satellite radar interferometry data from the Sentinel-1a/b missions, we observe a seasonal glacier acceleration of 15% in the summer, from 1,250 m/yr to 1,500 m/yr near t...
