Abstract

The relations of the beam attenuation coefficient with Secchi disk depth in three parts of spectrum for the Mediterranean Sea waters are established. Beam attenuation coefficient spectra in wavelength range 416-677 nm for waters with Secchi disk values of 9 m and 33 m are retrieved using the system of orthogonal vectors. The shape of spectra in oligotrophic and eutrophic waters of the Black and Mediterranean Seas, Atlantic and Pacific Oceans is compared. The influence of different components of sea water on the variability of spectral shape of beam attenuation coefficient is shown.
