Seafloor ploughmarks on the mid-Norwegian continental shelf reveal iceberg trajectories during the last glacial period
… curvilinear depressions interpreted as iceberg ploughmarks were mapped across the mid-Norwegian continental shelf using high-resolution swath bathymetry data. The orientation and morphology of each iceberg ploughmark was calculated and analysed, with features being up to 30 km long and 500 m …

Iceberg-keel ploughmarks on the seafloor of Antarctic continental shelves and the North Falkland Basin: implications for palaeo-glaciology
The use of iceberg-keel ploughmarks as proxy indicators of past and present iceberg morphology, keel depth and drift direction has seldom been approached in the southern hemisphere. Using high-resolution multi-beam swath bathymetry of the mid-shelf Pine Island Trough and outermost Weddell Sea shelf …

The Quaternary evolution of the mid-Norwegian continental margin
… glacial–interglacial cycles. Evidence of iceberg ploughmarks found within the earliest Quaternary Naust surfaces documents a marine-terminating, calving Fennoscandian Ice Sheet margin extending periodically onto the mid-Norwegian shelf since the earliest Quaternary. Buried subglacially-produced …

Submarine Geomorphology of the Continental Shelves of Southeast and Southwest Greenland from Olex Data
… was rapid. In Southeast Greenland, iceberg ploughmarks suggest that initial retreat from the shelf edge was characterised by the calving of deep-keeled icebergs. In contrast, gullying offshore of inter-ice stream areas and evidence of meltwater sedimentation in Southwest Greenland, indicate …
