| The nitrogen cycle between dissolved inorganic and organic matter, phytoplankton, zooplankton, non living particulate organic matter, and sediments is studied in the ecosystem formed by the Southern Bight of the North Sea. A consistent pattern of mean annual fluxes of nitrogen based on the primary production and the zooplankton grazing is set up. A mathematical model describing the dynamic behaviour of nutrients, phytoplankton, zooplankton and dissolved organic matter is proposed. The results of the simulation fairly well fit the recent observations made in the frame of the Math. Model Sea Research Programme. |

| The present work aims at establishing a mathematical model which describes the seasonal evolution of the most characteristic constituents of the pelagic phase of the ecosystem in the southern bight of the North Sea. After the notions of system and model, as applied to the analysis of the marine environment, have been defined, the different analytical forms that are required to describe the various ecological interactions are explained and the principal ecological models which were published in the litterature are reviewed. They are divided into five distinct categories. The experimental data which have enabled the establishment of the mean yearly cycles of nitrogen through the different compartments of this particular ecosystem are then examined. These... |
