Cross-cutting activity: Modelling

To cover the wide spatial range from open ocean dynamics to small coastal embayments, two hydrodynamic cores are used at IOW, the General Estuarine Transport Model (GETM) [] for the coastal to shelf sea scales and the Modular Ocean Model (MOM) [] for the shelf sea to open ocean scales. For both hydrodynamic models, IOW researchers are substantially involved into the model development. Another model development strongly linked to IOW is the General Ocean Turbulence Model (GOTM) [] which is a one-dimensional water column model providing a turbulence closure module to GETM and MOM and many other ocean models world-wide. As biogeochemical module, the Ecological Regional Ocean Model (ERGOM) [], a medium complexity biogeochemical model, has been developed at IOW since almost two decades and applied for a wide range of studies, being directly linked to the MOM hydrodynamic core. Since a Code Generation Tool (CGT) [] has been developed at IOW which allows for the development of biogeochemical models using a meta-language, ERGOM model code can be generated in various code formats to support different host models. One of these code formats is compatible with the Framework for Aquatic Biogeochemical Models (FABM) [] which links biogeochemical models in a flexible way to hydrodynamic models including GETM, MOM and GOTM. Interactive coupling between GETM and the wave model SWAN is implemented, and the interactive coupling to the atmospheric model ICON is planned. For flexible and modular coupling with other components (waves, atmosphere, sediment), GETM is integrated into the Modular System for Shelves and Coasts (MOSSCO) []. Within the Flexible Modeling System (FMS) MOM is coupled to a dynamic ice model. Output of GETM and MOM results for Live Access Servers (LAS) and webGIS is supported.
