Distribution of particulate trace elements in the Northeastern Atlantic
Provedor de dados: 27
Autores: Dauby, P.; Baeyens, W.F.J.; Biondo, R.; Bouquegneau, J.-M.; Chou, L.; Collette, O.; Dehairs, F.A.; Elskens, M.; Frankignoulle, M.; Loijens, M.; Paucot, H.; Wollast, R.
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...

General description of the Scheldt estuary
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Van Eck, B.T.M.; Lambert, C.; Wollast, R.; Goeyens, L.
A general description of the Scheldt estuary, including the hydrology, the sediment transport, the productivity and the biodegradation with respect to their influence on the trace metal behaviour in the Scheldt estuary, is given. The river basin can be divided in several sections according to their morphological, hydrodynamical and sedimentary properties. The zone from km 78 to 55, which corresponds roughly with the salinity zone from 2 to 10 psu, is the zone of high turbidity, high sedimentation and of oxygen depletion, especially in the summer period. That area is called the geochemical filter because the solid/dissolved distribution of the trace metals is controlled by redox, adsorption/desorption, complexation and precipitation/coprecipitation...

Sedimentologisch onderzoek van de Spuikom te Oostende
Provedor de dados: 27
Autores: Wollast, R.; Dehairs, F.A.
Thirty sediment samples of the Scour Basin in Ostend were analysed for the boulder content, detric elements, carbonates, organic material and their Zn, S, Cu, Mn and P concentration were determined. Then correlations between all these factors were determined. The spread of most factors appeared bound to those of the boulder.

Primary production and nutrient fluxes in the Gulf of Biscay
Provedor de dados: 27
Autores: Elskens, M.; Chou, L.; Dauby, P.; Frankignoulle, M.; Goeyens, L.; Loijens, M.; Wollast, R.
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 &lt;i&gt;f&lt;/i&gt;-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 &lt;i&gt;f&lt;/i&gt; agree well on the shelf, slope and deep basin...
