| The estimation of chlorophyll concentration in marine waters is fundamental for a number of scientific and practical purposes. Standard ocean color algorithms applicable to moderate resolution imaging spectroradiometer (MODIS) imagery, such as OC3M and MedOC3, are known to overestimate chlorophyll concentration ([CHL]) in Mediterranean oligotrophic waters. The performances of these algorithms are currently evaluated together with two relatively new algorithms, OC5 and SAM_LT, which make use of more of the spectral information of MODIS data. This evaluation exercise has been carried out using in situ data collected in the North Tyrrhenian and Ligurian Seas during three recent oceanographic campaigns. The four algorithms perform differently in Case 1 and... |

| This study is a complement to a previous study on the use of spatialised data for the optimisation of the surveillance of coastal waters in the Mediterranean within the European Water Framework Directive (WFD). This fisrt study aimed at characterising the ecological status of the coastal water masses through surface chlorophyll-A concentrations (Chl-A) derived from satellite imagery. The present study is focused on 3 main topics (i) a complementary characterisation of coastal waters with Suspended Particulate Matter (SPM) derived from satellite imagery; (ii) a hydrodynamic characterisation of the coastal waters based on outputs from the MARS-3D hydrodynamic model of Ifremer, by computation of the rate of renewal of the waters in each individual water mass... |
