Abstract
The distribution of organic and carbonate carbon in core samples from holes drilled in the shallow part of the Laptev Sea, in the region of Buor-Khaya Bay and Bykovskii Peninsula is considered. Significant heterogeneity in the distribution of carbon in the three columns studied is shown. Significant spatial heterogeneities in the distribution and burial of organic material (OM) under the conditions of a pulsing entrance of river and thermosabrasive material with repeated changes, as well as the mostly terrigenous origin of OM, are demonstrated.
