Shores of the East Siberian Sea

Shores of the East Siberian Sea – length of coastline comprises 5,918 km including the islands. The formation of the East Siberian Sea shores was influenced by general weakness of wave processes, caused by high ice coverage and good development of fast ice as well as evolvement of thermo-abrasive processes and instances of frost weathering. The coast of the East Siberian Sea within its official boundaries (the eastern boundary of meridian 108^°E) is divided in two distinctive parts. The bigger western part of the coast, stretching from the New Siberian Islands to the mouth of the Kolyma, is low and flat. Here the sea is being approached for almost 1,000 km by a vast Yana-Indigirka lowland which is formed by the most recent fluviolacustrine and alluvial, occasionally marine sediments and is covered by permafrost. All the northern part of this lowland that is adjacent to the sea is 200–250 km wide and presents a tundra with thousands of thermokarst lakes and alases. It is cut by big...
