Abstract
Analysis of conditions of formation of microplanktonic microbial communities (MC) was carried out for the Pechora Sea using the data of winter 2002–2005. The patterns of distribution of different MC groups in different water types are discussed. Regular variations of the indices of abundance in a gradient of physicochemical variables were revealed. The estimated average bacterial numbers for under-ice conditions were 234 × 103 cells/mL, with the average cell volume of 0.58 μm3 and total cell area ∼550 mm2/L. The estimated total microbial biomass in the 0–25 m water horizon of the Pechora Sea is 187 × 109 g wet biomass.
