Seismic reflection data show a local sedimentation bedform at the subglacial trough system of Isunnguata Sermia, West Greenland, September 2013
To check the possible presence of a subglacial lake in Isunnguata Sermia, West Greenland we collected two 5 km perpendicular profiles of seismic reflection data. The data revealed a 1.9 km by 450 m and 50 m thick lens-shaped body at the bottom of a subglacial 190 m deep trough, most likely consistin...
