Abstract: The aim of this work is the testing of MODIS standard products for chlorophyll -a and Sea Surface Temperature (SST) mapping on Mediterranean sea around Sardinia. The collaboration between TeleGis Laboratory and Biology and Ecology Department of University of Cagliari is carrying out an interdisciplinary research. From 2004 TeleGis laboratory acquire MODIS data by a direct antenna system daytime and nighttime and these data are stored in the original EOS hdf format. The Biology and Ecology Department is involved in the Project MEDITS which contributes to the characterization of bottom fisheries resources in the Mediterranean in term of population distribution (relative abundance indices) as well as demographic structures (length distributions), and provide data for modelling the dynamic of the studied species. In this scope, estimation of total mortality of the exploited species constitutes an important aim. From June 14 to July 7th 2006 an oceanographic cruise around Sardinia was organized to acquire data about bio- logical and biophysical parameters, with water samples to determine pH, salinity, conductivity, chlorophyll a concentration. In this work the first step of this research is presented, focused on comparison of these direct in- formation with the data model from MODIS images.
