Abstract :
Water-leaving spectral signatures were used in the spectral regions where chlorophyll has its first and second absorption bands in order to recognize biogeochemical provinces in the pelagic and coastal ocean. The global data set for MODIS used in this study data has a 4.89-km pixel resolution that is mapped on a cylindrical equidistant map projection. The data presented are based on an interpretation of the ratios R443/R551 and R678/R667 that use the spectral region of the two absorption bands of chlorophyll, the fluorescence of chlorophyll at 678 nm und the hinge point at 551 nm. Examples have been presented for eutrophic and oligotrophic oceanic regions.
