title: Long-term dynamics of spectral water transparency in the surface layer of Lake Teletskoye in summer
abstract: The article presents the long-term experimental data on spectral water transparency in the surface layer of Lake Teletskoye (21 sampling stations) obtained in summer of 2017‒2022. During the study period, values of the light attenuation index calculated at the natural logarithmic base at four wavelengths (430, 450, 550 and 670 nm) ranged within 0.2‒4.0 m‒1. The index of light absorption by yellow substance varied from 0.1 to 3.2 m‒1. Relative transparency measured with the use of a white Secchi
