Abstract:The abundance, cell size (cellular carbon content), and cellular pigments of picophytoplankton on the shelf area of the north Bearing Sea(61°29' 64°21'N, 168°00' 174°32'W) were analyzed by flow cytometry(FCM).A statistical analysis was used to study the response of the picophytoplankton to environmental changes. Synechococcus and picoeukaryotes were the only type of the picophytoplankton community; and their respective cell abundance was 0.01×106 2.69×106 and 0.47×106 13.20×106 cells/dm3. The chlorophyll a, phycoerythrin, and the cell size (cellular carbon content) had the same changing trend with the change of environmental factors. Comparatively, the chlorophylls a and the cell abundance, and the carotenoids and the cell size (cellular carbon content) of the picoeukaryotes had the same changing trends, respectively. Both salinity and nutrients had significant influence on the cellular carbon content and the ratio of carotinoids to chlorophylls a of picoeukaryotes. High nutrient concentration was prone to induce high ratio of cellular carbon content to chlorophylls a. Both synechococcus and picoeukaryotes preferred relatively high temperature and low salinity; and were easily to form high cell abundance in oligotrophic water, whereas in seawaters with relatively high nutrient concentration were prone to form cells with high cellular carbon content.The cell abundance of picoeukaryotes decreased intensely when the nitrogen-phosphorus ratio greater than 7. The cell abundance was relatively high, whereas the cell size (cellular carbon content) and the phycoerythrin-chlorophyll a ratio were relatively small. Comparatively, the cell size (cellular carbon content) and the phycoerythrin-chlorophyll a ratio were relatively large and the cell abundance was relatively low when the picophytoplankton was at relatively deep water layers and high latitudes. The ascending of the water temperature and the increase of the inflows of freshwater from the continent can increase both the abundance and the variety of picophytoplankton on the continental shelf of the north Bering Sea.
