The role of sea ice in coastal and sea bottom dynamics of the Pechora Sea

The article deals with the morpho and lithodynamic rote of ice in shaping the Arctic coasts. Taking the Pechora Sea as an example, the direct and indirect impact of ice an the seafloor and shores is described. The indirect impact of ice that blocks the coastal zone during the largest part of the year is considerable reduction of the Overall energy of waves and currents. Direct impact means active ice scouring by ice ridges, ice-rafting of sedimentary material, formation of strudel scours and frozen rocks an shallows. Based an the performed analysis, the scheure was plotted showing zonation of the Pechora Sea according to the probable ice impact an shores and seafloor.
