Abstract. As a result of the work, the structure of the Quaternary cover and bedrocks of the eastern slopes of the Perseus Rise and the sources of the Franz Victoria Trough was studied. The leveled top surface and slopes of the Perseus Rise are composed of Mesozoic bedrocks, which are overlain by a very thin cover of Quaternary formations. Based on seismoacoustic data, as well as materials from bottom sampling, we assumed that the hilly-ridge topography is the result of the impact of impact on the bottom of exogenous processes of unknown origin. Keywords: geological survey of the shelf, seismoacoustic profiling, bottom sampling, bottom rock material, Perseus Rise, Barents Sea
