Summary of measurements

-Niskin bottle samples at surface and/or at mid-depth. Zooplankton samples were taken in WP2 net over the entire water column.
Parameters studied: temperature, salinity, nitrites, nitrates, ammonium, silicates, phosphates, chlorophyll, primary production, phytoplankton flora, zooplankton flora, suspended matter, microbiology, haloforms, boron for Flamanville and Paluel.
-Paluel: 3 sampling points (Baseline, intake channel, discharge) all parameters.
-Penly: 4 sampling points (baseline, discharge, intake channel and control). All parameters except boron.
-Flamanville: 3 sampling points (baseline, intake channel, discharge). All parameters.
