Relief and structure of the upper part of sedimentary cover in the area of the Fedynsky Rise according to acoustic data

According to the analysis and interpretation of high-resolution acoustic data collected during 2011 marine expedition of the 28th cruise of the R/V «Akademik Nikolai Strakhov» in the southern part of the Russian sector of the Barents Sea shelf, the main genetic relief types were identified, and the thickness of the Quaternary sedimentary cover within the study area was determined. It has been established that the bottom area of the region under consideration is largely occupied by relic forms of aerial and subaerial origin, such as iceberg ploughmarks and pockmarks. Buried channel forms identified on acoustic sections in the Central Basin of the Barents Sea presumably belong to the Paleo-Pechora River drainage basin. Major patterns of the spatial distribution of various mezo- and microrelief types are considered, as well as their geomorphologic association to pre-Quaternary planation surfaces.
