Coastal Systems Modelling
Ecosystem modelling at the NIOZ started in the1980's in the project group BOEDE (Biologisch Onderzoek Eems-Dollard Estuarium) which studied the consequences on the Ems-Dollard ecosystem of the discharge of very large amounts of waste water mainly originating from the patato-processing industry. The experience from this modelling project was used by the NIOZ to initiate and coordinate an EU-project in the Marine Science and Technology program,1990-1995 where a consortium of 9 marine institutes developed the European Regional Seas Ecosystem Model (ERSEM). The specialization of the various institutes within a joint project on a European level was obviously the best way to tackle the formulation of a generic, system-based ecosystem model.

From 2004, NIOZ and Wageningen Marine Research cooperated in the NWO/ZKO-programme 'Changing carrying capacity in the Wadden Sea and North Sea coastal zone' and its sub-project 'Wadden Sea ecosystem data assimilation and integrated modelling'. Within this project, the ERSEM-GETM model has been applied to the Western Wadden Sea. Except for changes in the physical set-up such as the bathymetry, grid-size and vertical resolution, the only extension necessary was the inclusion of processes to model the dynamics of benthic diatoms. Thus, this application can also be seen as a test of the genericity of the ERSEM-formulation.
