The elemental composition of suspended particulate matter (SPM) in the Barents Sea was studied based on the materials of the 68th cruise of the RV Akademik Mstislav Keldysh, August 2017, using ICP-MS and AAS methods. SPM of the sea surface layer is characterized by significant heterogeneity in the elemental composition, which is due to differences in the course of biogeochemical processes over the water area (for example, high differences in the level of primary production) and different compositions of terrigenous matter from the sources. Biophilic elements significantly enrich the SPM of the surface water layer and fluffy layer relative to the average composition of the earth's crust (the degree of enrichment of the surface SPM is higher than the fluffy layer).

And Behavior

In order to clarify the origin and behavior of suspended particulate matter (SPM) in a tidal river, variation of SPM in a tidal river was investigated with regard to its size and constituents. SPM was separated into three groups according to size. Change of contents of titanium and organic substances of each group of SPM was examined. SPM which was discharged by run-off was transported with decomposition and sedimentation in a tidal river. Concentration of SPM with a particle size greater than 0.45 μm increased due to resuspension in a tidal river. Origin of SPM with a size of less than 0.45 μm at upstream areas was from natural soil and most of such SPM which had been transported settled near a river mouth. It was determined from examination of the CN ratio and the ratio of the number of attached bacteria to free bacteria that SPM with a size greater than 1.0 μm at upstream areas was decomposing intensively. At the downstream areas, SPM with a size of less than 0.45 μm came from the sea. SPM with particle size greater than 1.0 μm consisted of plankton and substances which were decomposed sufficiently while flowing.
