Freshwater carbon, which utilizes the absorption of carbon dioxide through photosynthesis by aquatic plants and phytoplankton, is attracting attention as a measure to reduce carbon dioxide. Previous studies have shown that stratification in freshwater lakes can significantly change carbon dioxide fluxes. However, more research is needed regarding the stratification formed by the presence of aquatic plants. Therefore, in this study, we conducted a field survey at Lake Akan and Chuurui Bay in 2022 and analyzed water temperature data, with the aim of evaluating the influence of aquatic plants on the formation of the surface mixed layer. The results showed that the presence of aquatic plants promoted the formation of a surface mixed layer. In addition, we introduced a novel formula, taking wind energy into account, to estimate the surface mixed layer thickness. This innovative approach demonstrated good reproducibility, sparking new avenues for research in this field.
