Summary

Most of the organic matter found in the sea is degraded in the seabed. A number of different bacteria are responsible for organic matter degradation. Through their metabolic processes bacteria form inorganic nitrogen and phosphorus compounds that are thus made available for new production. They also produce a number of waste products, such as hydrogen sulphide, that have a great impact on the marine environment. After many years of research, our knowledge of the processes going on in the seabed is substantial. This knowledge forms the basis of a new mathematical model linking the complex material cycles taking place in the seabed and describing the exchange of oxygen and nutrients between seabed and seawater. The construction of the model is described in this report. This report was prepared as a contribution towards developing NERI's expertise within the field of mathematical modelling.
