Synchronous Fluorescence Spectra as Chemical Tracers to Monitor the Organic Matter Dissolved in North Adriatic Waters
The use of synchronous fluorescence spectra as chemical tracers of the DOM in Adriatic Sea waters is here proposed. Laboratory experiments using both marine diatom cultures and natural phytoplankton provided evidence for the ability of the technique to characterize and quantify the extracellular products. Fluorescence parameters defined on laboratory cultures were applied to the study of the natural DOM present in the mixing area of the Po River with marine waters. The results support the effectiveness of the parameters to detect the contribution of the terrestrial as well as of the newly produced components mixed in seawater DOM. Experimental evidence was provided for the potential of the technique to trace the accumulation of the EOM in marine waters.
