Abstract
An extensive data base of in situ measured bio-optical parameters is analyzed to examine the influence of absorption of dissolved organic matter on upwelling radiance spectra. The measurements were carried out in the different water masses of the southern Baltic during various seasons of biological activity of the sea basin. Experimental data are the background of statistical relation between spectra of upwelling radiance, absorption of yellow substances and other sea waters constituents in the sea surface. The results allowed to preliminary assess the impact of yellow substance absorption on spectral distribution of upwelled radiance flux in the surface layer of sea water. The spatial and seasonal variability of this relation is considered. Particular attention is given to application of this results in remote sensing determination of water constituents.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
