Abstract
    This book, written primarily for a readership of 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 result of a multi-disciplinary investigation, called the BOEDE project, into the structure and function of an estuarine ecosystem which is heavily stressed by organic wastes from the potato-processing industry. The first two chapters describe the research structure and the scientific approach underlying the investigation. Chapter 3 treats the hydrography of the area and gives 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; both planktonic and benthic primary production, zoobenthos, zooplankton, nekton and both aerobic and anaerobic bacteria are treated in these chapters. Chapter 8 is devoted to dead organic material (detritus), its composition, and the mineralization of it. In chapter 9 the entire system is taken into consideration by comparing average biomasses and carbon fluxes. In chapter 10 simulation models are presented which describe the dynamical behaviour of the system. A general description of the modelling procedure as well as some results are given. The final chapter examines the role of the man-made stress to the Ems-Dollard estuary, and the ways in wich these stresses influence the ecosystem.
