Processes of early sediment diagenesis, including chemical composition of interstitial waters, content of different sulfur compounds, and rates of sulfate reduction were investigated. Along a profile from the Yenisey River to the Kara Sea, sulfate reduction intensities were high (up to 1.5 µg S/kg/day) in the delta region and in its northern part. Intensities were comparable to those found in shallow-water sediments of the North Sea. In estuarine sediments, where different transformations were possible, lower rates of bacterial sulfate reduction were observed (0.03 to 0.06 µg S/kg/day). Annual production of reduced sulfur in sediments was 24 million tons, and only 0.5 million tons (2%) were deposited. Annual consumption of organic carbon during process of sulfate reduction in the Yenisey delta region was 17.6 million tons.
