Glaciogenic, Fluvioglacial, and Fluidogenic Landforms on the Barents Sea Shelf

The results of bathymetric survey using multibeam echosounders are presented for the Barents Sea shelf. Geomorphological evidence supports the former presence of the Barents ice sheet. Glacial outliers (structures similar to “hill-hole pairs”) are found for the first time in the Russian sector of the Barents Sea. The present-day ice exaration grooves are studied. The sea depth, where submarine structures are unaffected by iceberg damage, is refined. Fluidogenic morphosculptures (pockmarks) are examined. The morphological features of rounded and elongated pockmarks are described. It is concluded on their current activity.
