Abstract

Calculations were made of the runoff of dissolved organic carbon (DOC) into the Kara Sea with the waters of the Ob and Yenisei rivers. The estimates performed showed that the DOC runoff with the Yenisei waters (3.67 × 10⁶ tC/year) is less than the DOC runoff with the Ob waters (4.06 × 10⁶ tC/year), which is due to differences in the structure of the drainage basins and estuaries of these rivers. All previous published estimates show the opposite. The lack of the DOC content data during the maximum flood of the Yenisei does not let us calculate accurately the DOC runoff with its waters, but makes it possible to estimate its maximum and minimum values (3.11–4.18 × 10⁶ tC/year).
