Deep-Water Glacial Plow Marks in the Western Margin of the Barents Sea

Data obtained from high-resolution multibeam echo sounding during the 26th cruise of R/V Akademik Nikolai Strakhov , maps of the Western Arctic bathymetry, the glaciomorphological characteristics of the last Eurasian Ice Sheet, and isobases of the seafloor uplift have been used for multi-layered cartographic compilation on the western margin of the Barents Sea shelf. Glacial plow marks at depths of 350–400 m were identified on the basis of detailed bathymetry data collected in the transition zone. The glacial plow marks are relict and correspond to the lines of the ice flow of the ancient Eurasian sheet. The seafloor relief, the position of the outlet paths of surges, and the thickness of the shelf glacier morphologically determine the orientation and depth of the plow marks.
