“…Particulate organic carbon is 40-90% deposited in estuarine zones and on the adjacent shelf, constituting the major part of the organic carbon flux to the bottom, which is confirmed by our long-term studies using sedimentation traps in the White and Barents Seas 12,16 (Fig. 1).…”

“…The flux of organic carbon to the bottom is calculated using the empirical relationship Fc = 33 PP/Z, where PP is the value of primary production in the water column and Z is the depth 2 . *novigatsky@ocean.ru; phone (499) 124-77-37; www.ocean.ru Studies of the fluxes of lithogenic and biogenic particles using long-term (more than a year) sedimentation traps in the northern high latitudes are still very rare and limited to the Arctic marginal seas and subarctic regions [12][13][14][15][16][17][18] . The method of sedimentation traps [19][20] makes it possible to determine benthic vertical fluxes (mgC/m 2 /day) of suspended particulate organic carbon (С bio ) quite confidently, despite some uncertainties in the form of active benthic hydrodynamics, nepheloid layers, daily migration of zooplankton, etc.…”

The studies have shown that the distribution of suspended particulate organic carbon in the seas of the Russian Arctic is characterized by сircumcontinental and vertical zonalities. These zonalities are manifested in decreasing concentrations and therefore fluxes (mgC/m2 /day) of suspended particulate organic carbon in the transition from the near-continental to pelagic areas of the Arctic Ocean, as well as from the surface photic layer to the near-bottom layer by two orders of magnitude, which is confirmed by instrumental data of sedimentation traps and correlates with the zoning of bio-production processes.

The distribution of suspended particulate matter (SPM) by filtration and the magnitude of its fluxs using sediment traps in the Kara and Laptev Seas (cruise 72 of the R/V Akademik Mstislav Keldysh, August–September 2018) was studied. The composition of the SPM was determined by the material composition using an electron microscope, the organic component (Corg and hydrocarbons) and the inorganic component (amorphous silica and calcium carbonate). It was found that the SPM content in surface waters varied from 0.2 to 5.9 mg/L (on average 0.90 mg/L) with a maximum in the Blagopolychia Bay and aliphatic hydrocarbons from 10 to 49 µg/L (average 22 µg/L) with a maximum in the area of the removals of the river Ob. The SPM flux decreased from the surface to the near-bottom horizon only into the Blagopolychia Bay (from 13,127 to 11,900 mg/m2/day), but in most samples the flux increased in the near-bottom horizon with a maximum of 6920 mg/m2/day in the Ob’s discharge water area and correlated with the maximum of the Corg flux 695 mg/m2/day. In the composition of SPM, as well as in organic compounds, including hydrocarbons, allochthonous basically prevailed over autochthonous.
