dc.description.abstract In September 1999 two short-term moorings with cylindrical sediment traps were deployed to collect sinking particles in bottom waters off the Ob and Yenisei river mouths. Samples were studied for their bulk composition, pigments, phytoplankton, microzooplankton, fecal material, amino acids, hexosamines, fatty acids and sterols and compared to suspended matter and surface sediments in order to collect information about the nature and cycling of particulate matter in the water column. Results of all measured components in sinking particles point to an ongoing seasonality in the pelagic system from blooming diatoms in the first phase to a more retention system in the second half of trap deployment. Due to a phytoplankton bloom observed north of the Ob estuary, flux rates were generally higher in the trap deployed off the Ob than off the Yenisei. The Ob trap collected fresh surface-derived particulate matter. Particles from the Yenisei trap were more degraded and resembled deep water suspension. This material may partly have been derived from resuspended sediments.
