Ciliates, naked dinoflagellates and small species like cryptomonads were common in the phytoplankton samples from the Skagerrak and Kattegat areas. In the Kattegat, diatoms were common. A few potentially toxic species were found in low amounts. The filamentous cyanobacterium Nodularia spumigena* had reached N14 Falkenberg with the Baltic current. However, the high salinity in the area prevents the blooms that occur in the Baltic Sea during summer. The integrated chlorophyll concentrations were within normal for this month. Threadlike cyanobacteria were still numerous at many of the Baltic stations. This confirms what the satellite surveillance has been reporting, that surface accumulations are present in the southern and southwestern parts of the Baltic Proper. http:// www.smhi.se/en/weather/sweden-weather/1.11631. The Baltic samples were rather species rich, but small species were the most numerous ones and small colony forming cyanobacteria were found in all of the samples. The integrated chlorophyll concentrations were within normal for this month at all stations except at BY38 where the concentration was below normal.
