Simulation of the marine environment has become an important tool across a
wide range of human activities and hydrodynamic models have reached a high
level of sophistication. However, sustainable management of the ecological
resources of coastal environments demands an ability to understand and
predict the behaviour of the marine ecosystem. It is therefore highly
desirable to extend existing models to include chemical, biochemical and
biological processes. This paper describes the development of a fine-scale
three-dimensional coupled transport/ecosystem model of the Northwest
European continental shelf and explores the particular problems
encountered in its implementation on high-performance computer systems.
