Reconstruct recent and past climate and environmental change by investigating lake deposits

We want to reconstruct recent and past climate and environmental change by investigating lake deposits using multiple proxies and dating strategies in combination with growing season reconstructions based on recent and fossil Salix polaris leaf material. The proposed research will lead to: 1) better understanding of base-level natural environmental changes in arctic environments over the last thousands of years; 2) quantification of the impact of recent climate change on artic environments; 3) contribute to the knowledge of relative sea-level changes by dating the isolation of the lake basins; and 4) explore the potential of tephrostratigraphy to reconstruct atmosphere dynamics.
