Abstract. As a result of complex geological and geophysical studies conducted in the summer of 2022, new data on the structure of the cover of quaternary sediments were obtained on the 21st flight of the NIS "Academician Boris Petrov". Based on the interpretation of geophysical data, the ideas about the upper part of the section and the features of the Central Kara trench are compiled. Presumably, characteristic wave patterns for deposits of Upper Pleistocene and Holocene age in the studied area have been identified. Further study of the materials will allow us to give a more complete history of the geological development and formation of the relief of the region in Quaternary time.
