The article presents the results of digitizing the maps of submarine permafrost on the shelf of the Arctic seas of Russia. Submarine permafrost mapping relies heavily on expert knowledge because there is a lack of data regarding the structure and thickness of permafrost. Maps compiled by different authors vary significantly due to the use of different approaches, paleogeographic scenarios, ideas about the geological structure, evolution of shelf permafrost, sea level and climatic changes. The first maps were based on the analysis of shelf morphology and seawater temperature; they represent only the assumed boundaries of the submarine permafrost distribution. Later, the distribution of submarine permafrost was associated with neotectonic movements on the modern shelf. As the first drilling and seismoacoustic data were received, more detailed maps were compiled, and the discontinuous distribution of submarine permafrost was substantiated, especially in the Western Arctic. By now, a large amount of seismoacoustic and drilling data has been accumulated, which has made it possible to create new maps based on these data. In recent decades, methods of mathematical modeling the formation and evolution of submarine permafrost have been rapidly developed. Calculated maps of the distribution and depth of submarine permafrost top in the Russian Arctic have been compiled. For the first time, it has become possible to predict the rate of degradation of submarine permafrost under climate warming.
