Abstract
The lidar fluorosensor equipment has ben used in an extensive marine campaign over the northern Adriatic sea. The apparatus, consisting of an UV lidar fluorosensor together with a laser fluorometer, has been installed on board of a small ship. The lidar fluorosensor was directly pointed to the marine surface, while the laser fluorometer was monitoring the water inside a cell continuously filed by a pump from one meter sea depth. The laser induced fluorescence (LIF) signals at selected wavelengths have been recorded by the two apparata to monitor the distribution of the different species. DOM and chlorophyll signals were detected upon excitation at (lambda) equals 355 nm, while organic pollutants and oils were excited at (lambda) #EQ 266 nm. In both cases, the corresponding water Raman signal was used for normalization. Absolute concentrations of different species were obtained, when possible, after calibrating LIF data against analytical chemical results on a number of water samples. The distribution of several substances, such as industrial pollutants, anthropogenic releases and chlorophyll from phytoplankton were obtained along the ship route. A differential GPS instrument installed on board of the ship has been used to precisely georeference the data, in order to produce thematic maps of the investigated areas containing the distribution of the different monitored species.
