phytoplankton species composition, CTD, nutrients\nLineage: Vertical profiles of the water column were obtained with Seabird CTD instruments with two auxiliary photosynthetically available radiation (PAR) and fluorometer sensors, a SBE 9, fitted with 12 ten litre bottles on a rosette sampler and one hand operated CTD instrument, a SBE 19Plus, used in the river. Profiles contained pressure (converted to depth (m)), conductivity (converted to practical salinity units), temperature (°C) and photosynthetically active radiation (PAR, 400 to 700 nm). Samples for nutrients, total suspended solids (TSS), cell count, chlorophyll a and pigments by HPLC were obtained from General Oceanics Niskin bottles at the surface and at the bottom or at the surface only in river. Yellow highlights in CTD files indicate downcast.
