Seasonal variability of plankton blooms in the Ria de Ferrol (NW Spain): II. Plankton abundance, composition and biomass

The abundance, taxonomic composition and biomass of plankton components were studied in the mostly eutrophic waters of the Ria de Ferrol (Galicia, NW Spain) in contrasting seasons. Three stations arranged in a transect along the main ria axis were sampled during cruises in February, May, July and Se...

Description
Summary:The abundance, taxonomic composition and biomass of plankton components were studied in the mostly eutrophic waters of the Ria de Ferrol (Galicia, NW Spain) in contrasting seasons. Three stations arranged in a transect along the main ria axis were sampled during cruises in February, May, July and September 2000. Phytoplankton, bacteria, micro- (40–200 μm) and mesozooplankton (>200 μm) compartments were considered. Phytoplankton blooms (>10 3 cel ml −1) and high total plankton biomass (up to 44 g C m −2) was found at all seasons, except in winter when values were
