| From 1989 to 1992, five cruises were conducted in an area covering the English Channel, the Celtic Sea and the Gulf of Biscay. During these campaigns, suspended matter was collected by different techniques in order to analyze the spatial and vertical distribution of several particulate trace elements in relation to the global biogeochemical cycle of carbon. It appears that horizontal distribution varies strongly from one element to another and is mainly influenced either by anthropogenic and terrigenous inputs or by scavenging processes. On the other hand, the vertical distribution seems mainly linked to the primary production. In parallel to these trace element measurements, experiments were carried out to estimate the transfer rates of these elements... |

| Since the role of continental shelves and coastal areas in the global biochemical carbon are nowadays a leading concern in oceanographic research programmes, this study aims to define the specific effect of nutrients on the onset and development of the phytoplankton bloom at the ocean margins. Comparison experiments of the carbon, nitrogen and phosphorus assimilation rates were carried out from 1989 to 1991 in the English Channel and the Gulf of Biscay. New production were obtained from the traditional approach using <i>f</i>-ratio values, i.e. the ratios of directly measured nitrate to carbon uptakes and/or the ratios of nitrate to nitrate plus ammonium uptakes. Values of <i>f</i> agree well on the shelf, slope and deep basin... |
