Abstract—Comprehensive geological, geophysical, geomorphological, and hydrophysical studies were carried out on the R/V Akademik Boris Petrov in the eastern Barents Sea and western Kara Sea in fall 2022. The research included multibeam echo sounding and seismic profiling, hydrological sounding, and sampling of water and sediments in the areas of oil and gas field development and along the Northern Sea Route. The expedition studied in depth the structure of the seabed relief and upper sedimentary strata at the given research sites. The distribution areas of various glacial landforms and modern geohazards were refined during the expedition.
Keywords: Barents–Kara shelf, seabed relief, glaciation, geohazards
