| Abstract: | The Northern Adriatic Sea is a shallow ocean basin with considerable fresh water input and presents some unique water-optical features realted to:- suspended matter input caused by rivers and resuspension of bottom sediments;- phytoplankton production because of nutrient input from rivers and bottom;- dissolved organic matter (yellow substance) production by decomposition processes of the organic material.All these features influence the spectral reflectance of the water and make the algorithms for CZCS data interpretation quite different from those used in open ocean (type I) water. Therefore, special test-site specific algorithms must be derived from in-situ measurements of water-optical parameters and the water constituents. The results from such measurements are presented together with the algorithms and the evaluated CZCS data obtained from them. It is then discussed how the experimental and evaluated satellite data can be used to evaluate standing crop and productivity. |
