The monograph deals with the activity of sea ice as an agent of active and passive topographical feature formation. The zoning of the coastal shelf zone was carried out according to the types of ice formations and their impact on the sea coast and the floor. The monograph provides a description of the morphology and morphometry of the exarational and other forms of the relief, the formation of which is associated with the dynamics and seasonal presence of sea ice. An attempt was made to correlate the intensity of ice impacts and the safety of the forms of ice grinding. The book assesses the impact of climate change and ice cover on the dynamics of Arctic coasts. The monograph is intended for a wide range of readers: from scientists and professionals - oceanologists, geomorphologists, engineers engaged in the design of hydraulic structures in the offshore shelf zone of the freezing seas, to students and postgraduates studying the physical essence and geography of natural processes in the Arctic, Caspian and other natural regions.
