The general objective of this research (financed by L.R. 7 of the Autonomous Region of Sardinia for the period May 2010 –May 2012) is to calibrate bio-optical algorithm for more accurate estimates of phytoplanktonic Chl-a in the Asinara Gulf (Northern Sardinia, Italy) using remote sensing data and in situ measurements. The “sea truth” values of Chl-a were obtained with the new laser spectrofluorometric apparatus CASPER (Compact and Advanced laser SPEctrometeR – Patent ENEA). CASPER permitted not only to quantify values of Chl-a but also to detect other algal pigments (phycoerythrin, phycocyanin), chromophoric dissolved organic matter (CDOM), proteins-like components (tyrosine, tryptophan), and qualitative data on the presence of hydrocarbons and oil pollution. At the moment “sea truth” data of Chl-a were just compared to standard chlorophyll products of MODIS OC3 algorithm. In order to reach better results, the bio-optical algorithm is going to be recalibrated according to the measurements of CASPER during the next year, thus providing new estimates of phytoplanktonic Chl-a in the Asinara Gulf. |
