- Аннотация: The results of biohydrogeochemical monitoring are used to study time-dependent variations in the hydrogeochemical characteristics of the Lake Karymskii water mass, the state and characteristics of underwater discharge zones in the Tokarev crater ( formed in 1996), hydrogeochemical characteristics of thermal springs around the lake, and the biota succession in the lake for the period 1996-2006 ( 2007). We detected a stratification in the chemical composition of water over depth and the presence of persistent zones of increased concentrations of dissolved oxygen. We found an alkalization of lake water and a decrease in its total salinity. The new thermal springs and underwater discharges of thermal water and gases were found to be continuing. The first data were obtained on the concentration of microelements in the thermal springs of the Karymskii basin. The biodiversity of algae in Lake Karymskii was largely increased by the species diversity of benthic Bacillariophyta. The plankton
