Port of returnPort-Saint-Louis-du-Rhône, France
PurposeResearch
ObjectivesEMCM, OBS, pressure sensor and grab sample surveys of the lower 7 km of the Rhône river, as well as the mouth area (delta top and delta front). Objectives were to gather information on river conditions prior to SED2 cruise deployments (13-16 April 2004), and to collect bottom samples for continued analysis of the relationship between river plume and bottom sediment distribution.
This cruise was the fourth in a series planned for the Gulf of Lions (see also AR1-2003, FR1-2003, AR1-2004) within Workpackage 1 (Shelf and River input systems) of the European Union FP5 project European Margin Strata Formation (EUROSTRATAFORM) (EVK3-CT-2002-00079). EUROSTRATAFORM objectives are to explore the fate of sediment particles from their source in rivers through to their deposition on shallow deltas, the continental shelf and deep sea basins.
