| contents | Particles of detritus were counted by size-groups and microplankton cells in samples stained with acid fuchsin and acridine orange. Data were obtained for eutrophic and oligotrophic waters. Seston in the eutrophic layer of eutrophic waters consists of 22-65% phytoplankton, 3-18% microzooplankton, and 32-65% detritus; in oligotrophic waters - of 3-7% phytoplankton, 1-5% microzooplankton, and 92-97% detritus. Amount of detritus in seston increases with depth up to 4.4 µg C/l (sigma = 1.48) at 500-4000 m. Microplankton biomass in deep water contains mostly olive-green cells and bacteria; no microzooplankton <200 µm long was found below 200 m. Aggregates 10-50 µm in diameter and fragments of organisms 50-200 µm long were dominant by weight among detrital particles. No discernible associations of microorganisms with detrital particles were observed. |
