Use of SeaWiFS data to estimate water optical properties of the Black Sea

Since 1997 the U.S. satellite sensor SeaWiFS is providing an information, that can be helpful to monitor Black Sea waters in routine operational mode. Due to the errors inherent in atmospheric correction procedures, the possibilities to determine the full spectrum of normalized spectral water-leaving radiance are very limited. At the same time the analysis shows that the use of two SeaWiFS channels at 510 and 555 nm allow us to detect many interesting features of temporal and spatial variability of the effects of absorption and scattering of light in the Black Sea.
