The phytoplankton diversity varied along the Swedish west coast. At Anholt E and Släggö it was moderate whereas Å17 and N14 Falkenberg had few cells and mainly small ones. Relatively high cell abundance of the coccolithophore Emiliania huxleyi was found at all stations. The integrated chlorophyll concentrations were within normal for this month all stations.
Overall the phytoplankton community in the Baltic Sea consisted of small cells with a total domination of really small cells at some stations. Different ciliates were also common in most samples. A few filaments of different cyanobacteria were also found at several stations The integrated chlorophyll concentrations were within normal for this month at most of the Baltic stations the only exception were BY15 and BY38 were the concentrations were a bit above what is normal.
