Аннотация:This article deals with the morpho- and lithodynamic
role of ice in shaping the Arctic coasts. Taking
the Pechora Sea as an example, the direct and indirect
impact of ice on the sea floor and shores is described.
Active gouging by ice floes, ice-rafting of sedimentary
material, formation of strudel scour depressions and
frozen rocks on shallows are all direct impacts. The
indirect impact of ice that arrests the coastal zone for
most of the year is a considerable reduction of the
overall energy of waves and currents. Based on the
performed analysis, we plot a schematic zonation of
the Pechora Sea according to the probable impact of ice
on the shores and seafloor.
