The Northeast Greenland continental shelf is only sparsely mapped due to its remoteness and harsh year-round sea-ice conditions. Mapping the distribution of submarine glacial landforms relies mainly on single track lines of multibeam echo sounder bathymetric data with only occasional systematic surveys. Ice streams drain the modern Greenland Ice Sheet [GrIS] to its northeastern margin in several fjords near the head of the Westwind Trough (Fig. 1a). The presence of glacial lineations and recessional moraines in the inner to middle trough indicates that the GrIS extended onto the continental shelf probably during the Last Glacial Maximum (Evans et al. 2009; Winkelmann et al. 2010).
