Abstract
The proposed research project will give us a better understanding of natural processes, especially those relating the carbon, nitrogen and sulphur cycling in lakes that represent the basis for understanding of global environmental and climatic changes. Lake sediments can provide important historical information on changes that affected situation and quality of aquatic ecosystem. Stable isotopes of carbon, nitrogen and sulphur are important indicators of temporal changes in fluxes or cycles of carbon, nitrogen and sulphur compounds. The purpose of this project is to provide new data for reconstruction of paleoproductivity, input and accumulation of C, N and S in the sediment, and anthropogenic impact on eutrophication processes in remote protected areas (Triglav National Park). Combination of chemical and isotopic analyses will enable us to gain data that will be used in modelling for quantification of element cycles. In a selected eutrophic alpine lake, that represents due to its smallness a model environment where the input and output parameters can be controlled, important biogeochemical processes (methanogenesis, nitrate and sulphate reduction) will be studied. Investigations in some other alpine lakes (oligotrophic, mesotrophic) will be done for comparison too. Results of the project will be used for study of C, N, S cycles in bigger sedimentary basins with similar conditions.
