A method for evaluation of the absorption coefficient of conservative yellow substance (CYS) from regression between hydrooptical characteristics is discussed. Estimates of CYS absorption in different waters are obtained. The parameter of spectral selectivity of CYS absorption is determined. The ratio of CYS absorption to total yellow substance absorption in waters with different concentrations of chlorophyll is calculated.
