Composition of organic matter in suspended matter and bottom sediments of the southeastern Baltic Sea, supplement to: Nemirovskaya, Inna A; Sivkov, Vadim P (2012): Peculiarities in the distribution of hydrocarbons in the southeastern part of the Baltic Sea. Translated from Okeanologiya, 2012, 52(1), 40-53, Oceanology, 52(1), 34-47


Data on contents and compositions of hydrocarbons (HCs)-aliphatic (AHCs) and polycyclic aromatic (PAHs) are provided in comparison with contents of total organic carbon (Corg), lipids in suspended matter, and Corg in bottom sediments. Particular attention is paid to distribution of HCs in the area of the Kravtsov oil field. It is established that concentrations of AHCs in water are governed by concentrations of suspended matter and elevated AHC concentrations are confined to coastal areas. In the area of D-6 platform sandy bottom sediments are notable for great variability of HC concentrations, both laterally and from year to year. In summer of 2010 average content of AHCs was 40 ppm (19% of Corg) and that of PAHs was 0.023 ppm. Natural seepage from sediment mass is considered to be a source of HCs along with oil contamination.
