Influence of salinity and light climate on phytoplankton in the Schelde estuary

In this study, we tested the effects of light intensity and salinity on estuarine phytoplankton communities of the Schelde River and Estuary. We used HPLC in order to identify and quantify the different phytoplankton pigments. In two experiments (summer-spring), water was collected in the river and at two locations in the estuary (freshwater tidal and brackish). The water was mixed with an equal amount of filtered water (GF/C filters) from the same or a different site and was exposed to different light levels to test for the effects of the chemical composition of the water (including salinity)...
