Environmental conditions of the Baltic Sea’s (BS) ecosystem strongly depend on meteorological forcing over the area and adjacent NE Atlantic. It affects e.g. regional hydrography and saline water inflow from the North Sea into the BS. These changes are recorded in the BS sediments. We aim to identify forcing mechanisms of environmental changes of the BS, to differentiate natural variability and changing patterns due to man-made activity, by studying these sediment archives. In addition we will provide scenarios of the future development of the BS.
The acronyme INFLOW arises from the project title "Holocene saline water inflow changes into the Baltic Sea, ecosystem responses and future scenarios".
Understanding the past is the key for predicting the future
We will study ongoing and past changes in both surface and deep water conditions and their timing by means of multi-proxy studies. We use sediment proxy data along transect from the marine Skagerrak to the freshwater dominated northern BS. We have identified following aims:
Proxy reconstructions will be compared to results from model simulations. We will use these evaluated models to provide selected scenarios of impact of naturally and human induced climate change on the BS ecosystem at the end of the 21st century.
