Abstract. The preliminary results of the relief and sediments of the ice-gouging landforms study of the Kara Sea, carried out during the 56th cruise of the R/V “Akademik Nikolai Strakhov”, are presented. The survey of the ice-gouging landforms was carried out at 22 sites, on which ice gouges with depth of up to 10,0 m and up to 260 m wide were recorded. The maximum length of the ice gouges was 45 km. The cores of bottom sediments are taken both directly from the bottom of the ice gouges and from an undisturbed background surface for comparative dating of the ice-gouging relief using the content of the non-equilibrium 210Pb and anthropogenic 137Cs. The ice-gouging landforms investigation was supported by the Russian Scientific Fund (project 21-77-20038). Keywords: ice gouges, bottom topography survey, multibeam echo sounder, bottom sediment cores, Baydaratskaya Bay
