IMIS

Flow cytometry analyses were performed every hour from the same inlet water as the FerryBox during the survey. Discrete samples were taken using CTD rosette at 4 metres to calibrate the chlorophyll fluorescence. The analysis of the phytoplankton functional types were done manually (according to the knowledge of the operator), and the discrete samples were analysed by HPLC (DHI, Denmark). All data from the FerryBox (fluorimetry, turbidity, salinity, temperature, oxygen) as well as HPLC and flow cytometry followed specific quality controled procedures before being available.
