Book Description
stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges. In general, organic matter has isotope ratios characteristic of its origin (e. g. plants with different modes of photosynthesis and different growth conditions, anthropogenic compounds). These ratios are maintained as the organic matter moves through the biosphere and geosphere. A mixture of organic matter from two sources has isotope ratios intermediate between those of the two sources, in proportion to the fraction of material from each source. Isotope ratios are one of the few methods which can trace organic matter as it moves through natural ecosystems. Ratios can be measured on both the total organic matter and on particular chemical fractions or compounds. When used on organisms, isotope ratios provide information of organic matter actually assimilated into body tissues, not just material ingested. As with all tools, this method has certain limitations which must be borne in mind when interpreting its results. Firstly, specific environmental conditions must be met. This generally means an ecosystem with a limited and known number of sources of organic matter having different isotope ratios. Two sources with different isotope ratios are ideal; additional sources with other isotope ratios complicate interpretation. Secondly, the difference in isotope ratios of the two sources should be large compared with analytical variability. Thirdly, the ratios within each source should vary as little as possible.

Book Description
This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature. The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities. Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water. Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.

Book Description
This Workshop was organized to assess the status of knowledge on the behaviour of phosphorus in sediments and to define gaps and reassess research strategies, particularly with respect to prevalent methodology and future approach; and to define gaps and reassess research strategies for water management measures in aquatic ecosystems, especially in relation to the release of phosphorus from the sediments and its impact on the functioning of the whole system.

Book Description
The UK Land-Ocean Interaction Study (LOIS) provided a major opportunity to measure and model the processes controlling the fluxes of materials between river basins and coastal seas. The main programme of research took place between 1992 and 1998, funded by the UK Natural Environment Research Council, and involved approximately 360 coastal researchers contributing to more than 70 collaborative projects. This book presents accessible summaries of key results of this research. The ten chapters of the book are written by leading contributors to the programme, and cover aspects of the physical, sedimentological, chemical and biological processes controlling fluxes between river catchments and coastal seas in temporate environments. Major overarching themes for all of the chapters include the persistence, storage, degradation and transport of pollutants from catchment to coastal sea, and an emphasis on the relevance of research for river and coastal water quality management. The chapters also describe a number of important technological advances in the measurement of processes and longer term monitoring of the fluvial, estuarine and coastal environments. Approaches to monitoring were also transferred between disciplines, in many cases for the first time. The rivers and coastal programme of LOIS was unique in its scale and inter-disciplinarity and its results are of lasting value. This book provides a useful and important summary of many of its results and an effective introduction to the research for those who want to delve more deeply into the data and published papers. It will be of interest to scientists, environmental managers and scientific policy makers.
