Abstract. The preliminary results of the relief and sediments of the ice-gouging landforms study of the southwestern part of the Kara Sea and the north-eastern part of the Barents Sea, carried out during the 51st cruise of the R/V “Akademik Boris Petrov”, are presented. The survey of the ice-gouging landforms was carried out at 16 sites, on which ice gouges with depth of up to 10,0 m and up to 450 m wide were recorded. The maximum length of the ice gouges was 11.1 km. The core 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, anthropogenic 137Cs and heavy metals (Pb, Sb, Cd, Tl, Bi). 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, East-Novaya Zemlya trough
