PurposeResearch
ObjectivesBathymetric, ADCP and sidescan sonar survey of the lower reaches of the Rhône river to the mouth after the large Rhône flood in December 2003. This cruise was intended originally to complete survey lines not covered during the bathymetric survey of cruise AR1-2003. However, due to bathymetric changes caused by the December 2003 flood, it was decided to collect river profiles to enable a comparison with the pre-flood (November 2003) profiles. Strong Mistral winds meant that it was only possible to collect data during one of the four planned survey days.
This was the third cruise in a series planned for the Gulf of Lions within Workpackage 1 (Shelf and River input systems) of the European Union FP5 project European Margin Strata Formation (EUROSTRATAFORM) (EVK3-CT-2002-00079) (see also AR1-2003 and FR1-2003). 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.
