A manual for phytoplankton primary production studies in the baltic

 · Unlike nutrients and Chl. a, phytoplankton composition of the Baltic proper has not been analysed statistically for trends by HELCOM and in earlier investigations (Kononen and Niemi, ). Reasons for this might include the complicated structure and incomplete quality assurance of the phytoplankton data bank, high variability in species composition for natural Cited by: Gargas E () A manual for phytoplankton primary production studies in the Baltic.

As primary production is, at least in the summer months, limited mainly by nitrogen (Granéli et al., ), phytoplankton biomass should be correlated with nitrogen concentrations. Total phytoplankton biomass can be reflected by Chl. a concentration because this constitutes the dominant pigment of photo-autotrophic organisms. The spring bloom of phytoplankton typically produces up to half the annual production of algal biomass during a relatively short time period (2–6 weeks), and the phytoplankton community is dominated by relatively large ( 10 μm) diatoms and dinoflagellates, with little grazing pressure (Lignell et al. ; Wasmund et al. ). We analyzed phytoplankton primary production, heterotrophic bacterial production and chemolithoautotrophic dark CO 2 fixation along with concentrations of oxygen and inorganic nutrients in the Baltic Proper and in the Gulf of Riga during June At the time of our study, North Sea water derived from a major Baltic inflow during the previous winter season had propagated to the Gotland Basin.
