A shipborne fluorosensor laboratory has been built and used for extensive marine campaigns to monitor the quality of different seawaters including Mediterranean, Northern sea and Antarctic Ross sea. The core of the system is a compact lidar fluorosensor capable of single or dual laser excitation of the target. In the single excitation mode the detection of different chromophores characteristic of water impurities is possible, while the dual laser excitation is necessary to monitor the phytoplankton photosynthetic activity on the chlorophyll emission channel. A lamp spectrofluorometer, a pulsed amplitude fluorometer (PAM) and a solar radiance detector complete the set of instruments on board. Georeferenced data have been collected and released on thematic maps of the different seawater quality parameters (phytoplankton concentration, yellow matter, turbidity, biomass productivity, organic pollutants) remotely and in situ monitored during several marine campaigns.
