Chlorophyll a content (mg/m3) from May to July in the last
year of monitoring at sampling station S1 (the cages) is given
in Table 6. The phytoplankton biomass slightly increased from
May, but till July it was still below 1 mg/m3. The chlorophyll
a content increased from the bottom to the surface.
Skeletonema costatum and Chaetoceros compressus were
dominant species (90 %) in summer chlorophyll.
