Organic Carbon Flow in the Ob, Yenisey Rivers and Kara Sea of the Arctic Region

摘要

Stable carbon isotope and elemental C/N ratios of the organic fraction of a set of samples along a transect in the Ob and Yenisey Rivers into the Kara Sea in the Arctic Were measured. Previously, the concentrations of ~239,240Pu And ~137Cs in these same samples had been determined. The Coupled measurements were carried out to assess possible Connectivity between organic carbon flow into the Kara Sea and transport of radioactive nuclides in this marine Environment.
