| Summary: | Investigations of bottom sediments from the central and northern parts of the Norwegian Sea including study regions at the Storegga landslide, the Haakon Mosby mud volcano, and Knipovich Ridge were carried out. Concentration of n-alkanes in bottom sediments from these regions ranges from 0.53 to 22.1 µg/g of dry sediments that corresponds to 0.02-1.97% of Corg. Molecular composition of hydrocarbons indicates mixed allochtonous-authochtonous genesis of total organic matter (TOC) formed by hydrobiota and residuals of terrestrial plants. Terrigenous organic mater dominates in bottom sediments. Active redox, microbial and thermolytic processes of organic matter transformation take place in the sedimentary mass. Special character of chromatographic spectra of n-alkane distribution in both low and high-molecular ranges, as well as increased naphtene contents can be interpreted as a sign of oil hydrocarbon generation from maternal organic matter as a result of thermocatalytic reactions within sedimentary mass and ... : Supplement to: Peresypkin, Valery I; Romankevich, Evgeny A; Aleksandrov, A V (2004): Studies of the organic matter composition in the bottom sediments of the Norwegian Sea.
