    The Banc d'Arguin is an area of tidal flats and shallows situated between roughly 19 degree 20' and 20 degree 30'N along the Saharan coast of Mauritania. It is characterized by water temperature of about 20-25 degree C and salinities over 38. There are no rivers and rainfall is rare. Off the coast of Mauritania cold water masses from the Atlantic and warm water from tropical areas meet. Hence flora and fauna contain both temperate and tropical species. Examples are the temperate mudsnail Hydrobia ulvae and the seagrass Zostera noltii , and the tropical mangrove Avicennia africana and the bivalve Anadara senilis. Conspicuous features are extensive seagrass beds, relatively low biomasses of the zoobenthos and extremely high densities of birds (Wolff & Smit, 1990). The project Banc d'Arguin 1988 endeavoured to understand the functioning of this remarkable coastal wetland. Major questions to be answered concerned the interaction between the Banc d'Arguin ecosystem on the one hand, and the adjoining systems of the open ocean with its intensive upwelling phenomena, and of the Sahara desert on the other. To evaluate the results of the project Banc d'Arguin 1988 a symposium was held in the National Museum of Natural History at Leiden, The Netherlands, from 25-27 March 1991. At this symposium the results of the 1988 project have been placed in perspective by inviting a number of key scientists who reported on research at the Banc d'Arguin by Mauritanian and French institutions.
