Abstract

An advanced method of measuring the volume scattering function (VSF) of seawater and a unique instrument based on this method are presented. The approach differs from traditional ones and involves the use of a special periscope prism that allows to determine VSF directly over a wide range of angles (0.5°–178°). Experiments performed using artificial suspensions, including bubbles, polystyrene monodisperse beads and biological particles, showed a good agreement between theory and scattering measurements. Measurements of angular scattering in nanopure water provided additional proof of existence of two-dimensional irregularities of molecular structure at the scale of 10-7–10-3m. This allowed to conclude that optical properties of pure water are determined by liquid-like aggregates consisting of H2O molecules and impurity elements. The new data obtained in numerous research expeditions showed that there is a significant environmental variance in the VSF at small angles near forward direction as well as at the angles near 180°. These results are of fundamental importance to the accurate modeling of the propagation of radiation in the ocean.
