- Аннотация: The East Siberian Sea (ESS) is governed by a complex system influenced by seawater of Pacific origin entering from the east and water of Atlantic origin entering from the west. To explore the role of picophytoplankton and its response to different water masses, abundance, composition, contribution to total primary production and chlorophyll a, and environmental parameters were analyzed along two transects located on the shelf of ESS in September 2017. The results showed that the structure of the picophytoplankton community was water-mass-specific in the autumn: Micromonas polaris dominates in the western area of the ESS, influenced by Atlantic waters, while Bathycoccus prasinos dominates in the eastern area of the sea, influenced by Pacific waters. The average picophytoplankton abundances and primary production were higher in the eastern area than in the western area. A possible explanation is Pacific inflow to the eastern area of the ESS that slightly changes the nutrient balance, which, together with low radiation in autumn that limits the growth of large phytoplankton, gives an advantage to small phototrophic algae. These findings indicate the necessity of further studies of regional variations in the function and distribution of picophytoplankton to clarify the effects of changes in the Arctic environment on the marine ecosystem.
