| 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... |

| Vertical distributions and diel migrations at nineteen stations located in the Ligurian and Tyrrhenian Seas (northwestem Mediterranean) are described in detail and compared for the main species of micronekton and macroplankton. Sampling was performed in April 1994 in the 0-700 m water column in most cases, down to 350, 450 or 550 m for the coastal or relatively shallow sites. Most of the twenty species showed similar distributions throughout the sampled area, either non-diel-migrating distributions such as the euphausiid Stylocheiron longicorne and the fish Cyclothone braueri, or clear diel-migrant behaviour (e.g. the siphonophore Chelophyes appendiculata and the euphausiid Euphausia krohni). Four species, the siphonophore Lensia conoidea, the pteropods... |
