92d cruise of R/V “Akademik Mstislav Keldysh” was organized by Shirshov Institute of Oceanology in a frame of long-term Program “Marine Ecosystems of Siberian Arctic” and was held from 5 October to 7 November 2023. 76 scientists from the institutes of Russian Academy of Sciences, National Research Center Kurchatov Institute, Moscow State University, Moscow Institute of Physics and Technology, VNIRO and MES of Russia participated in the cruise. Coordinated hydrophysical, hydrochemical, biooceanological, geochemical research were carried out in the eastern part of the Kara Sea in the period of seasonal ice formation, as well as in the Ob river estuary and fjords of Novaya Zemlya archipelago. Conditions of largest disposals of radioactive waste in the Kara Sea were evaluated.
