Abstract:
Vertical fluxes of autochtonous detritus at different levels were estimated using the algorithm of structure-function analysis. The calculations are based on pelagic ecosystem parameters in the Kara Sea observed in September 1993 (temperature, primary production, biomass of phytoplankton, bacteria, protozoa, and zooplankton, trophic and size composition, etc.). At eight stations in different parts of the sea where sedimentation traps were set, the range of calculated fluxes of autochtonous detritus through the lower boundary of the water column was 13-90 mgC/m**2/day. The flux was much higher in the estuary of the Yenisey River (55-90 mgC/m**2/day) than in the northeastern regions (I8-50 mgC/m**2/day) and, especially, in the relatively deep southwestern part of the sea (13-35 mgC/m**2/day). The calculated fluxes of autochtonous detritus in shallow water regions (where conditions are variable and poorly known hydrologically and where outflow of allochtonous detritus is substantial) cannot be compared to data from sedimentation traps.
