Structure of the transition zone from the barents sea shelf to the Knipovich Ridge Northward from Medvezhii Island (Preliminary results of the 26th cruis of R/V Akademik Nikolaj Strakhov

265 The works of the 26th cruis of R/V Academik Nikolaj Strakhov scientific research vessel showed that the Barents Sea shelf located north of Medvezhii island experiences lift and erosion delivering terrige� nous material for fan systems from the shelf edge to the Knipovich Ridge. Bottom relief indicates the presence of tectonic fracturing in the region of intensive iso� statitical process in a continent–ocean transition zone and traces of movements of icebergs formed at differ� ent times. The survey in the zone of the Knipovich Ridge from 74°40 ′ to 75°20′ N indicates intensifica� tion of neotectonic processes on the eastern side of the rift valley and increase of their amplitude to 1.5 km. The nature of deformations of the sedimentary cover testifies to the continuation of Riedel fractures under sediments on the eastern side and confirms the right
