Abstract

The sunlight spectral composition, penetrating to different depths in the upper water layer, on the one hand, depends on the optically active components contained in the water, on the other hand, it is important for the functioning of phytoplankton, and therefore plays an important role in the functioning of the aquatic ecosystem in general. When studying the spectral composition of light at different depths, a new instrument was used, made on a modern elemental basis. Analysis of the obtained spectra of the vertical attenuation coefficient made it possible to identify regional features of the penetration of natural sunlight characteristic of Lake Teletskoye.
