WADDEN SEA PROJECT

Objective


Within 2 years 2 field experiments have been conducted. Several concepts for the coupling of numerical models for the simulation of complete ecosystem scenarios of the Wadden Sea have been planned. The necessary software has been realized and to some extent also validated. Submodels for the atmosphere, the sea to atmosphere interface and the various transport processes in the water column as well as numerical models for the biological and chemical processes have been modified to run interactively, exchanging their information within appropriate time steps, instead of being subjected to fixed boundary conditions. In previous approaches those boundary conditions were externally prescribed, whereas in nature they are influenced and modified by the simulated submodel processes. Progress was made in modelling biological and chemical processes and coupling them to other processes of ocean and atmosphere. Progress was also achieved in modelling transport of matter and in investigation of nearshore air to sea interaction processes.
PROJECT DESCRIPTION:
An interacting chain of models will be set up for the Wadden Sea, describing atmospheric oceanographic processes, ocean waves, sediment transport and ecological processes. In all the mentioned individual disciplines there are still some research deficiencies especially within the area of influencing each other. Especially the influence of ecological processes on the physical properties has to be investigated. The oceanographic models will be close to those used by the national weather centres. Several sediment transport models will be compared with available data since there is not much experience with the quality of sediment models. For the ecological modelling common understanding on the importance of different mechanisms in the Wadden Sea will be achieved.
