Abstract

During the expeditions of the Institute of Oceanology of the 38th and 41st voyages of the RAS R/V Academic Nikolai Strakhov (2018–2019) in the Pechora Sea between the Kanin Peninsula and Kolguyev Island. Kolguyev revealed a large number of accumulative sandy bottom landforms and characterized a number of their parameters. In 2022 (51st cruise of the R/V Academic Boris Petrov), the study of such relief was continued in order to clarify the area of their development, morphology and dynamics.
