The monograph examines the activity of sea ice as an agent of active and passive relief formation. Zoning of the coastal-shelf zone was performed according to the types of ice formations and their impact on the shores and bottom. A description of the morphology and morphometry of exaration and other relief forms, the formation of which is associated with the dynamics and seasonal presence of sea ice, is given. An attempt was made to correlate the intensity of ice impacts and the preservation of ice plowing forms. An assessment of the impact of climate change and ice cover on the dynamics of the Arctic coast is given.
