Abstract

The results of calculations of the spatial distribution of bottom deformations in the bottom area of the Pechora Sea at different wind directions are presented. It is shown that bottom erosion dominates on the shelf, while in the coastal zone the storm of the prevailing directions cause accumulation of sediments. The shoreline is mostly receding, which ultimately should lead to a flattening of the offshore coastal slope. It is concluded that there are large-scale relatively isolated lithodynamic cells in the coastal zone. The mass of sediment displaced during a storm is measured in hundreds of tons per square kilometer of seabed and increases with increasing wind speed. The bulk of material is transported during storms in a strip of depths from 10 to 30 m.
