Аннотация: The Arctic shelf is the most important link in the climatic kitchen of our planet: here, under the influence of the flow of the great Siberian rivers, a layer of freshened water is formed, blocking access to the surface of relatively warm saline waters of the North Atlantic origin, which prevents the melting of the ice cover of the Arctic basin Thus, the processes occurring in the relatively small size of the Arctic region, are able to change the state of the planetary scale system. Such active attention to this problem is associated with the development of offshore oil and gas fields. Permafrost established under the bottom of the Arctic seas occurs at a distance of up to 120 km from the coast, at a depth of several tens of meters. The temperature of the sea day is an important characteristic in assessing the state and direction of the evolution of sub-permafrost. To solve the part of this problem we tried to make bathymetric and temperature GIS of costal and offshore permafrost in Barents and Kara Seas. The GIS is based on the sea depth, temperature, and salinity of sea water collected by the marine organizations of Russia, the USA, England, Germany, Norway and Poland for the Barents and Kara Sea regions from 1898 to 1998. From all sources in the areas of the Barents and Kara Seas, more than 1,000,000 oceanographic stations were selected for processing. These maps are only the part of the GIS project.
