Abstract
The paper deals with a comparative analysis of the data on in-situ measurements of spectral water transparency in the range of 400–800 nm for some sections of Lake Teletskoye water area during stable summer and winter temperature stratifications. Field trips were conducted in summer of 2016–2019 and during the freezing period of 2018. The description of the device developed for measuring spectral underwater irradiance by depth at wavelengths of 303, 361, 590 and 656 nm as well as the measurement results made in the summer of 2018–2019 are presented. The data on distribution of spectral underwater irradiance by depth at maximum height of the Sun and cloudlessness are given. It is revealed how many times spectral transparency increases during the freeze-up period (when the water area covered by ice) as compared to lake warming in summer. Dynamics of changing relative transparency in sites of the lake’s water area according to white disk is shown for different years. The obtained results make it possible to rank the lake water area by anthropogenic and natural impact of the catchment.
