Abstract. This works presents preliminary interpretation of data, collected during expedition TTR-21 of MSU in the northern part of the Kara Sea. The fieldwork was executed on the board of IO RAS research vessel “Akademik Boris Petrov” in July-August 2022. Due to combination of sediment coring with seismic and hydroacoustic methods such as very high-resolution seismic profiling, acoustic profiling and multibeam echo-sounding, data on quaternary sediments structure and geomorphology of Kara Sea bottom was retrieved. Bedforms located at one of the research area key sites are considered here. Their morphology and origin are described.

Keywords: Kara Sea, TTR-21, very high-resolution seismic profiling, acoustic profiling, multi-beam echo-sounding, subequal geomorphology
