Climate forcing factors for marine environmental change during the mid and late Holocene - a link between the eastern Atlantic and the Baltic Sea (CLIMLINK)
ClimLink "Climate forcing factors for marine environmental change during the mid and late Holocene - a link between the eastern Atlantic and the Baltic Sea" aims to reconstruct mid to late Holocene climate induced ecosystem changes in the eastern Nordic Seas, Skagerrak, Kattegat and Baltic Sea. Linkages and common forcing factors that drive climate changes and their effects will be identified. The following hypotheses will be addressed: 1) The state of the Nordic Seas inflow determines the inflow of saline water in the Baltic Sea, 2) minor changes in the Atlantic can cause major changes in the Baltic sector, and 3) the oceanic conditions of the eastern Nordic Seas and Baltic Sea are driven by common forcing factors. These hypotheses will be addressed based on highresolution micropaleontological and geochemical reconstructions to be performed on a transect of sediment cores strategically located in the Norwegian Trench, Skagerrak, Kattegat, Arkona Basin, Bornholm Basin and Gdansk Bay. Furthermore, there will be a strong emphasis on optimal chronological control to secure a sound basis for placing these reconstructions in a stratigraphic context, and hence, establish an integrated mid to late Holocene climate change history of the North Atlantic and Baltic Sea. The integrated reconstruction of regional climate change will be used in combination with regional downscaled model simulations to identify internal and external forcing factors, climatic and environmental effects.
