Biogeochemical Processes at the Land-Sea Boundary
There is an intuitive belief among scientists that each estuary or lagoon is unique and different. Similarities do exist, however, and this book attempts to highlight some common properties and perhaps some innovative views on biogeochemical processes, and biological fluxes which are of central concern in the understanding of the land-sea boundary. The contents are based upon lectures given at a Seminar organised as the scientific component of the 17th General Meeting of SCOR, held at the Station Biologique de Roscoff, France, on 22-24 October 1984. The original lectures have been substantially extended and revised in order to give a fuller treatment of the subject. The contributions identify important processes influencing (I) Behaviour of chemical species, (II) Nutrient cycling and mechanisms of organic transformations and (III) Uptake of trace elements by living systems. The connection between terrestrial and oceanic systems is a functional one and the consequences of this linkage on the very large variety of coastal systems are profound. It is widely recognized that many of the major processes which influence the biological properties and chemical forms of elements, and their biogeochemical cycles in the ocean occur at the land-sea boundary, especially in estuaries, coastal lagoons, the coastline and the shelf. Over 80% of living systems and their fisheries take place in near shore waters and the consequential production of organic matter produced triggers off the high level of activity. Over the last fifteen years, there has been considerable stimulus to provide framework to evaluate the interactions and effects of human activities. The rich assemblage of tables and figures and of literature citations contained in the chapters provides an excellent basis for in-depth investigations.Oceanographers, limnologists, aquatic chemists, marine biologists, and environmental specialists will find this book highly valuable reading for advanced research and training purposes.View full description
