    Biomarkers in surface sediments from the Ob and Yenisei estuaries and the southern Kara Sea (2003)
    PANGAEA
    In:  Supplement to: Fahl, Kirsten; Stein, Ruediger; Gaye-Haake, Birgit; Gebhardt, Andrea Catalina; Kodina, Ludmilla A; Unger, Daniela; Ittekkot, Venugopalan (2003): Biomarkers in surface sediments from the Ob and Yenisei estuaries and the southern Kara Sea: Evidence for particulate organic carbon sources, pathways, and degradation. In: Stein, R; Fahl, K; Fütterer, D K; Galimov, E M & Stepanets, O V (eds.), Siberian River Run-off in the Kara Sea: Characterisation, Quantification, Variability, and Environmental Significance, 488 pp. Proceedings in Marine Sciences, Elsevier, Amsterdam, 6, 329-348

    Description: Organic-geochemical bulk parameter (Total organic carbon contents, C/N ratios and d13Corg values), biogenic opal and biomarkers (n-alkanes, fatty acids, sterols and amino acids) were determined in surface sediments from the Ob and Yenisei estuaries and the adjacent southern Kara Sea. Maximum TOC contents were determined in both estuaries, reaching up to 3 %. Relatively high C/N ratios around 10, light d13Corg values of -26.5 per mil (Yenisei) and -28 to -28.7 per mil (Ob), and maximum concentrations of long-chain n-alkanes of up to about 10 µg/g Sed clearly show the predominance of terrigenous organic matter in the sediments from the estuaries. Towards the open Kara Sea, all p arameters indicate a decrease in terrigenous organic carbon. Brassicasterol as well as the short-chain n-alkanes parallel this trend, suggesting that these biomarkers are probably also related to a terrigenous (fresh-water phytoplankton) source. Amino acid spectra show characteristic trends from the Yenisei Estuary to the open Kara Sea revealing increasing state of degradation. Sedimentary organic matter in the Yenisei Estuary is relatively less degraded compared to the Ob Estuary and the open Kara Sea.
