Remote sea-water quality monitoring by means of a lidar fluorosensor
- ENEA, Frascati (Italy)
The lidar fluorosensor, built at ENEA Frascati to remotely monitor the sea-water quality by collecting the water Raman backscattering and induced fluorescence from dispersed oils, suspended matter and chlorophyll, has been employed in a marine campaign in the lower Adriatic sea. Extensive calibration measurements have been undertaken by analyzing with the lidar, both in the laboratory and during the campaigns, sea water samples taken at several places along the Italian coasts. Absolute values of organic matter chlorophyll concentrations have been obtained by calibrating the lidar data with standard physical-chemical methods. This system has been recently upgraded for detecting the photoplankton photosynthetic activity, by means of the pump-and-probe technique, which has been assessed to monitor the process in microalgae during laboratory experiments.
