Coastal Modeling Framework (COAST)

Based on the coupled model system COAST (Coupled cOAstal model SysTem) developed at the Helmholtz Centre Hereon, new model instruments are being developed as part of Coastal Futures to better address specific questions regarding the protection and utilization of coastal regions. COAST is a model system that flexibly integrates the key components of regional and coastal modeling and additionally allows the incorporation of information from observations. Thus, it provides the ideal foundation to:
i) investigate physical processes in the atmosphere, ocean, and the role of waves at the atmosphere/ocean interface. In Coastal Futures, the atmospheric model COSMO-CLM, the ocean model NEMO, and the wave model WAM are dynamically coupled. The goal is to understand the interaction of components and their variability under changing environmental conditions at regional and interregional scales.
ii) better understand the impact of climate change and anthropogenic stressors, such as the influence of offshore wind energy and fisheries, on the coastal ecosystem. Therefore the model framework is expanded with more accurate models for various fish species. This includes coupling ECOSMO E2E with the multi-species model OSMOSE (Wolfshaar et al. 2021) and the implementation of Individual-Based Models for juvenile fish .
iii) examine the impact of climate change on the distribution of key species. For this purpose habitat models for fish, marine mammals and sea birds are integrated into the model framework.
iv) conduct simulations for the analysis of biogeochemical processes by coupling the ocean model NEMO with the biogeochemical model ECOSMO-E2E.
