Water color study of the Adriatic Sea

Pigment spatial and temporal variability was studied from long-term CZCS observations. The three Adriatic sites, Northern, Middle, and Southern Adriatic are differently influenced by meteorological, hydrological and oceanographic parameters, pointing out to some differences in the underlying mechanism of the pigment variability in these areas. The phytoplankton dynamics in the Northern Adriatic, as reflected in chlorophyll a, is especially influenced by the river runoff, which intensively enrich nutrient supply and mixing of shallow bottom sediments, which are induced by the strong wind. The differences between seasonal course of in-situ chlorophyll and remotely sensed pigment concentrations (from CZCS satellite data) from the Adriatic are especially large in winter. However, in-situ chlorophyll changes are in accordance with the course of transparency for the Northern and Middle Adriatic. Meteo-oceanographic and hydrological data are compared to the satellite pigment concentrations from different Adriatic sites, in order to give some information about possible causes of these differences.
