Abstract. The total number of planktonic bacteria in the upper mixed layer of the Bering Sea during the late spring-early summer period ranged between 1 and ~4 x 106 ml"1 (biomass 10-40 mg C nr3). In the northern Pacific, along 47-52°N, the corresponding characteristics of the bacterioplankton...

Their populations were dominated by naked forms of Strombidium, Strombilidium and Tontonia. In some shelf areas, up to 40 % of the total ciliate population was represented by the symbiotic ciliate Meso-dinium rubrum. The data on the integrated biomass of basic groups of planktonic micToheterotrophs are also presented, and their importance in the trophic relationships in pelagic communities of subarctic seas is discussed.
