This book, written primarily for decision-makers in the various government agencies concerned with the management of the estuary, describes the Ems-Dollard ecosystem and the forces operating on the ecosystem. The book contains the results of the BOEDE project, a multi-disciplinary investigation into the structure and function of an estuarine ecosystem which is subject to considerable stress as a result of the discharge of organic wastes from the potato-processing industry. The first two chapters describe the research structure and the scientific approach underlying the investigation. Chapter 3 deals with the hydrography of the area and provides an introduction to the biology of the system. In chapter 4 an overview of the behaviour of nutrients is given, as well as a description of the oxygen cycle. Chapters 5-7 describe the main biological components and the processes regulating them: planktonic and benthic primary production, zoobenthos, zooplankton, nekton and aerobic and anaerobic bacteria. Chapter 8 is devoted to dead organic material (detritus), its composition and mineralization. Chapter 9 considers the entire system by comparing average biomasses and carbon fluxes. In chapter 10 simulation models are presented which describe the dynamic behaviour of the system. A general description of the modelling procedure as weIl as a number of results are given. The final chapter examines the role of man-made stresses in the Ems-Dollard estuary, and the ways in which these stresses influence the ecosystem.
