DYNAMICS OF PERMAFROST IN THE COASTAL ZONE OF EASTERN-ASIAN SECTOR OF THE ARCTIC

DYNAMICS OF PERMAFROST IN THE COASTAL ZONE OF EASTERN-ASIAN SECTOR OF THE ARCTIC

The study summarizes results on the cryogenic dynamics in the coastal zone. The paper shows that ongoing climate warming and shrinking of ice extent of the Arctic seas triggers both thermogenic and cryogenic processes at the same time. The first group includes thermal abrasion, thermal denudation, d...
