Ecosystems of Siberian Arctic Seas-2019: Spring Processes in the Kara Sea (Cruise 76 of the R/V Akademik Mstislav Keldysh)

Abstract—The large-scale expedition of cruise 76 of the R/V Akademik Mstislav Keldysh was performed by the Shirshov Institute of Oceanology from July 1 to August 6 2019 within the Program “Marine Ecosystems of the Siberian Arctic.” Seventy-one scientist from Russian Academy of Sciences institutes, Moscow State University, and VNIRO participated. Coordinated hydrophysical, hydrochemical, biooceanological, geochemical, and radioecological research was carried out over the shelf and continental slope in the Kara Sea, Ob estuary, and in the eastern coastal bays of Novaya Zemlya.
