a Modeled ice-flow lines at the Last Glacial Maximum (black lines; modified after Patton et al.28). Black box shows the study area and location of (b). Borehole 7316/6-U-1 has Pleistocene glacio-fluvial channel infill52. Bs: Bellsund fan, Hs: Hornsund fan, If: Isfjorden fan, Sb: Sjubrebanken trough mouth fan, Sf: Storfjorden fan. b Study area with relevant borehole locations (white dots). The Senja Ridge (golden polygon), the extent of the 3D seismic survey (black envelope), regional seismic section (red line), seismic profiles (black lines and black numbers, with white numbers associated with the white envelope, indicate figure locations), and areal extents of Figs. 5, 6, and 7 (white stippled line) are indicated. Slope channels and glacial lineations on the present seafloor are shown as insets. Shaded relief maps from mareano.no. c Uninterpreted and interpreted seismic section across the study area, highlighting the Bear Island Fan and the shelf edge on a regional scale. The Quaternary sediments of the SW Barents Sea are thin on the shelf and thicken in the Bear Island Fan. Modified from Lasabuda et al.20. Seismic data courtesy of TGS/Spectrum.
