Coupling different modelling platforms: an activity across Fram Centre Flagships

Our aim is to link ice, oceanographic and biological sub-models developed in different modeling platforms enabling the setup of complex models for any region within the areas studied by Fram Centre institutions. Besides the proposed modeling work, the project focuses on establishing collaboration between different research groups in the Fram Centre that can benefit from high quality ocean modeling. In addition to the model development, we will strengthen the already established forum on multi-scale modeling. The deliverable of the project will be a user friendly tool linking modeling components from well-established modeling platforms into a coherent whole and with great flexibility, for usage in different environmental contexts and proposals to fund interdisciplinary research within the Fram Centre.
One of the main challenges in environmental and ecosystem modeling is the description of biogeochemical processes that is not always based on generally accepted theories. This leads to a large diversity in the way similar processes are described with different modeling software. Furthermore, when a model is setup for a new ecosystem, it is often necessary to include variables and processes specific to that system or especially important, as a function of the objectives for which the model is being used, and these may not be included in the available modeling software. Therefore, being able to “hybridize” different models developed in different programming environments will speed up the development process and utilize the strengths of the different platforms and developer traditions specific for the different scientific fields.
We will base the hybridization upon well-established structured and unstructured grid ocean models. These models have ocean, hydrodynamic and biogeochemical modules following different paradigms across different models.
