英文摘要	The results of studying the upper 20 m-thick Near-Yamal bottom shelf sediments, stripped in May 2014 by two boreholes of VSEGINGEO, have been presented. The boreholes were equipped with the loggers L for monitoring observations of temperature regime dynamics in the bottom sediments. This was necessary in connection with the prospective development of hydrocarbon deposits in the shelf. The results of the temperature change for three summer months of 2014 have been obtained. It has been revealed that the marine aleurolitous clays and aleurolites represent relict frozen strata subjected to cryogenic metamorphization in the subaerial conditions. The diatom complexes of clayey soils consist exclusively of marine extinct species typical of the Early Eocene Pyxilla gracilis diatom zone. A complex of modern marine sublittoral diatoms has been found in the sands of the near-shore borehole upper part.
