Abstract
The differences in the concentration of elements between thawed and frozen sediments were shown in the samples from two boreholes from the coastal zone of the Laptev Sea (Buor-Khaya Bay). The thalassogenic nature of enrichment of thawed deposits with sodium, chlorine, and to a lesser degree sulfur and phosphorus was confirmed. The difference in the concentration of chlorine between thawed and frozen soils may reach two orders.
