The paper is concerned to the problem to determine the light absorption in seawater by measuring properties of the light field. To highlight the multiple light scattering effects in a water body, the radiation transfer equation (RTE) in the depth regime is analyzed. The scattering phase function of the light by suspended particles was derived from the field VSF data (BLACK SEA BIO-OPT Oceanographic Campaign 31.08 - 16.09.2012). One-parametrical model of phase function accounted only variations in the proportion of molecular scattering. To calculate the deep water angular radiation distribution a new iterative procedure was applied. It is shown that in comparison with formulas of the two-flow approximation the characteristics of the light field exhibit greater non-linearity depending on the Gordon parameters.
