Assessing the Stability of Meromictic and Dimictic Lakes on Bolshoy Solovetsky Island

Research on the Solovetsky Islands reveals that nearly half of the 48 lakes analyzed exhibit meromictic conditions, with six confirmed through hydrological studies. These lakes maintain stable stratification due to chemoclines, which can be disrupted in autumn, leading to bottom water mixing. In contrast, dimictic lakes show resilience against wind-induced thermocline destruction during summer, with autumn mixing driven primarily by convective processes influenced by surface layer mineralization. The study combines morphometric data and hydrological assessments to evaluate lake stability and chemocline behavior, providing insights into the unique hydraulic dynamics of this UNESCO World Heritage Site.
