Hydrogeology of the artesian basins of the southern part of the Kara sea and Yamal-Gydansk megasaddle
Background. In hydrogeological terms, the territory of the Barents-Kara shelf has not been studied in sufficient detail. The data on its hydrogeological zoning are based mainly on the results of research undertaken in the 1970s, when attempts were made to isolate artesian shelf basins according to a...
