Abstract
To solve inverse problems, in particular, the recovery of optically active substances from hydro-optical measurements, it is necessary to clearly understand the nature of these dependencies. The work analyzes such relationships between the fluorescence of dissolved organic matter, chlorophyll-a fluorescence and the beam attenuation coefficient at a wavelength of 660 nm based on direct measurements performed in Lake Teletskoye in August 2023. It is shown that the waters of Lake Teletskoye belong to the so-called waters of the second type (CASE2) according to the Morel classification, i. e. optically complex waters.
