On the basis of a 39-year record of satellite-based data, three basic types of large-scale structures of sea ice drift that are typical for the winter season have been distinguished. The types of atmospheric circulation that create the structure of sea ice drift fields have been revealed. The mechanism by which the drift field variations affect the interannual variations of the extent of sea ice in...
The Bazhenov Formation is represented by Late Jurassic black shales. Russia is the first in the world by the reserves of shale oil, which is mostly related to the Bazhenov Formation. To reconstruct the sedimentation settings for the main types of formation of rocks, the distributions of lanthanides have been used. The results pointed to the formation of the Bazhenov deposits in relatively shallow...
