Абстракт
The effect of in water optically active components on spectral downwelling irradiance and on phytoplankton capacity to absorb light has been investigated in coastal waters of the Black Sea near Crimean Peninsula, where spectral light absorption coefficients of phytoplankton, non-algal particles and colored dissolved organic matter were measured in different seasons 2016. It has been revealed, that an increasing of content of optically active components effect on the spectral features of downwelling irradiance - shift of wavelength of the maximum of spectral downwelling irradiance to the longer wavelength on ~25-40 nm, which resulted in ~3 times decreasing of the spectrally weighted chlorophyll-a specific absorption coefficient. It has been shown that change in spectral downwelling irradiance, caused by content of any optically active components, is described by its relationship on ratio between light absorption coefficients of colored detrital matter and phytoplankton pigment (aCDM(440)/aph(440)), which is optical depth-dependent.
