Abstract

We consider a method used for the solution of the inverse problem of biooptics of the sea according to the spectrum of upwelling radiation and propose a procedure for the correction of the data of measurement by fixing the value of reflectance at a wavelength of 400 nm. The influence of this assumption on the results of retrieving of the concentrations of admixtures in seawater is analyzed. The computed values of the concentration of chlorophyll correspond to the data of direct biological measurements, and the reconstructed spectra of the absorption coefficient of phytoplankton have local maxima typical of biological particles. The applied correction allows us to decrease the influence of measurement errors on the results of retrieving and to increase the stability of solution of the inverse problem.
