Illustration of modular modelling system GCOAST (Grafics: Ha Hagemann / Hereon)
The GCOAST (Geesthacht Coupled cOAstal model SysTem) is built upon a flexible and comprehensive coupled model system integrating the most important key components of the regional and coastal systems and, additionally, allowing to include information from observations. Triggered by the need for novel modelling capacity, the GCOAST system is designed to handle cross compartment fluxes of water and energy between the atmosphere and ocean through the dynamic wave interface, dynamics and biogeochemistry in the land ocean transition and marine ecosystems and benthic-pelagic coupling, transport and transformation of environmental pollutants.
