Abstract

The MUSORSTOM 9 cruise was carried out in the Marquesas Archipelago from 18 August to 11 September 1997. 168 samples by dredging and trawling were made in the upper-bathyal zone and in the circalittoral depths, on the slope of the islands and on the top of the Dumont d'Urville Seamount. A terrace with a gentle slope is surrounding each island. Deeper than 100 meters the slope is very steep with from time to time terraces between 400 and 600 meters deep. The benthic fauna of this remote archipelago isolated in the Central Pacific is remarkably poor in all the groups.
