Features of the Distribution of Dispersed Sedimentary Matter Composition in the Nordic Seas

Two geodynamic sedimentary settings were studied in the sedimentary system of the Norwegian Sea – in the Lofoten Basin and in the zone of the junction of the Mohns and Knipovich ridges. Dispersed sediment samples were collected from different horizons of the water column, including the subsurface and benthic layers. Elemental and constituent compositions were studied, and the fluxes of matter were analyzed. The vertical and seasonal variability of individual components of the sedimentation system was also assessed. The distribution of the main sediment components in the two sedimentary settings differs insignificantly, several general patterns were identified. The presence of authigenic barite of different morphology in the subsurface horizon of the Lofoten Basin water column was noted.
