    Description: Using gas chromatography technique we examined molecular composition of n-alkanes and lignin from bottom sediments of a core 385 cm long collected in the region of the Blake-Bahama Abyssal Plain. We determined C_org concentrations and lignin composition in soils, mangrove roots and leaves, in algae Sargassum and Ascophyllum, in corals and timber of a sunken ship; they were compared with data on lignin in bottom sediments. Mixed planktonogenic and terrigenous origin of organic matter in the core was proved with different proportions of terrigenous and planktonogenic components at different levels. Multiple changes in dominating sources of organic matter over a period required for accumulation of a four meter thick sedimentary sequence (about 4 m) are shown as obtained from changes in composition and contents of organic-chemical markers referring to classes of n-alkanes and phenols.

    In:  Supplement to: Lein, Alla Yu; Savvichev, Alexander S; Rusanov, Igor I; Pavlova, Galina A; Belyaev, Nikolay A; Crane, Kathleen; Pimenov, Nikolay V; Ivanov, Mikhail V (2007): Biogeochemical processes in the Chukchi Sea. Translated from Litologiya i Poleznye Iskopaemye, 2007, 3, 247-266, Lithology and Mineral Resources, 42(3), 221-239, https://doi.org/10.1134/S0024490207030029

    Description: Study of biogeochemical processes in waters and sediments of the Chukchi Sea in August 2004 revealed atypical maxima of biogenic element (N, P, and Si) concentrations and rate of microbial sulfate reduction in the surface layer (0-3 cm) of marine sediments. The C/N/P ratio in organic matter (OM) of this layer does not fit the Redfield-Richards stoichiometric model. Specific features of biogeochemical processes in the sea are likely related to the complex dynamics of water, high primary produc¬tivity (110-1400 mg C/m**2/day), low depth of the basin (〈50 m for 60% of the water area), reduced food chain due to low population of zooplankton, high density of zoobenthos (up to 4230 g/m**2), and high activity of microbial processes. Drastic decrease in concentrations of biogenic elements, iodine, total alkalinity, and population of microorganisms beneath the 0-3 cm layer testify to large-scale OM decay at the water-seafloor barrier. Our original experimental data support high annual rate of OM mineralization at the bottom of the Chukchi Sea.

    In:  Supplement to: Peresypkin, Valery I; Romankevich, Evgeny A; Belyaev, Nikolay A (2003): Contents and molecular composition of alkane-naphthene hydrocarbons, lignin and lignin-derived phenols in the bottom sediments from the West-European Basin. Translated from Okeanologiya, 2003,43(3), 371-382, Oceanology, 43(3), 347-358

    Description: Three bottom sediment cores were collected from the top, slope, and foot of a small topographic high located near the West European continental rise within the Porcupine abyssal plain at the battleship Bismark wreck site. Using high-efficient gas chromatography technique we determined content and examined molecular composition of n-alkane fraction of hydrocarbons and phenol compounds of lignin. n-Alkane and phenol concentrations in bottom sediments of all three cores were low both in values per unit mass of sediments and in organic matter composition that is typical for pelagic deposits of the World Ocean. They vary from 0.07 to 2.01 µg/g of dry sediment and from 0.0001 to 0.01% of TOC; phenol ranges are from 1.43 to 11.1 µg/g and from 0.03 to 0.6%. Non-uniform supply of terrigenous matter to the bottom under conditions of changes in sedimentation environment in different geological epochs is the principal reason for significant variations in n-alkane and lignin concentrations with depth in the cores. Lignin and its derivatives make the main contribution to formation of organic matter composition of the region in study. With respect to n-alkane and lignin concentrations organic matter of deposits of the West European Basin is composed of remains of higher plants and of autochtonous organic matter of marine flora; they have mixed terrigenous-autochtonous (terrigenous-planktonogenic) origin.
