Coastdat - Home

coastDat is a model-generated database developed primarily to assess long-term changes in data-poor regions. A series of numerical models are used to reconstruct all aspects of the marine climate (such as storms, waves, storm surges, etc.) and ecosystems including hydrodynamics and biogeochemical processes over many decades, relying only on large-scale information such as large-scale atmospheric conditions. In this way, data is created that is as consistent and homogeneous as possible. Where possible, the reconstructions are supplemented by corresponding projections of climate change, which also enable an assessment of potential future changes. The approach was developed over more than 20 years ago and has been applied successfully to various issues in the North and Baltic Seas, including assessing the planning of offshore wind farms, changes in wind and storm surge climate or long-term changes in primary production and the effects of eutrophication. The coastDat dataset is used by more than 100 users, of which about 40 % are in the industry, 15 % in public authorities and 45 % in research institutes.
