Subsea Permafrost Thawing as a Factor of Changes in the Elemental Composition

Аннотация

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.
