Reihe: Developments in Hydrobiology

An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996. It was the third International Joint Conference on Limnology and Oceanography which brings together specialists of both environments. Considered to be necessary in Europe, this confrontation of two different aspects of common subjects could produce innovative approaches. The main purpose concerns scientific researches relative to the interfaces between various aquatic environment compartments. The principal treated topics are bioavailability and mobility of substances, influence of biotic and abiotic factors on transfers, and fluxes at the interfaces. It is particularly interesting to note the contribution of Limnologists and Oceanographers on the impact of nutrients and pollutants, and flux quantification of river basin inputs. As well as scientists, this book is also of interest to all engineers and consultants involved in teaching and working in aquatic management, restoration and enhancement.
