Abstract

Suspended matter entering Lake Onego with river runoff was studied from 2019 to 2021. Observations on rivers in different seasons on the basis of an interdisciplinary systematic approach combining modern landscape-geographical, biogeochemical, mineralogical, geochemical, hydro-chemical, ecological methods allowed us to gain new knowledge about the weighted average flow of substances into Lake Onego for seasonal variability.
