This study investigates in detail natural processes of modern sedimentation in South Baikal. The article presents data on the total flux of sedimentary matter, collected between March 1999 and March 2021. The quantity and composition of the recovered material is largely determined by SiO2bio, which is directly dependent on annual blooms of diatoms in the lake. Since 2010, particle fluxes have generally increased. At the same time, there was a change in the dominant diatom species. So called “Melosira years” were replaced by years with increased productivity of species of the genus Synedra. Presumably, this happened due to climate change.
