Results of research of spatial distribution of attenuation coefficient of light by sea water on 555nm wave length and temporal variability of this coefficient are given in this paper. Its is shown that optical structure of the White sea and spatial-temporal variability of this coefficient are closely connected with hydrological regime of the White sea and meteorological conditions of the region, as well as with various passive water admixture, which concentration changes influenced by continental (including river) drains, and depends on water exchange between the White and Barents Seas. Studies were conducted in summer 1995-1999 on more than 200 stations according to the standard grid of observations. Underwater spectral photometer created by the author of this work was used. The analysis of spatial distribution of attenuation coefficient of light by seawater in the White Sea has shown that water mass differs not only by TS-characteristics, but also by optical characteristics, hence attenuation of light by seawater can serve as an impartial marker of hydrological structure of the sea and its ecological condition.
