The paper deals with the development of destructive relief-forming processes at the coasts of the Arctic plains, by the example of Yugorsky peninsula. Geomorphic mapping and study of construction of thermocirques and flat bluffs allows estimation of the distribution of various relief forms and coasts of various types. Collation of the results of repeated measurements at the experimental sites and remote-sensing data is used to acquire the rate of thermocirque extension and shoreline dynamics. These data serves as a base for calculation of sediment and soluble salts removal from land onto the coastal zone.
