| Sumario: | Since the begining of the ECOMARGE (Program France -JGOFS), one of the most important questions addressed has been the transfer o f p a rticula te m a tte r over the shelf-break downon the slope and in to the deep sea. Several inorganic markers, such as quartz sand and detrital heavy mineral suites, were used to demonstrate the importance of shelf spill-over process. Biogenic markers were also considered. Downslope transport of shallow-water benthic foram iniferais a common phenomenon; hence, the study of displayed middle and outer shelf benthic foraminifera present in the slope cores provides good information about pathways of sediment transport such as submarine canyon. B en thicforamin ife ra l assemblages from the continental slope in the Cap-Ferret Canyon area yielded autochthonous populations from the upper bathyal, mid bathyal and lower bathyal zones. Transported fauna from the sublittoral and circalittoral zones were also found in the Cayon. They indicate a continuous input of material into the Canyon via the slope channels, particularly ip the southern and northern axis |
