Objective | Sedimentary processes and recordings on continental margins. The objectives were fivefold. (1) Surveying two drilling sites proposed for a new EU-funded research project called "PROMESS1". This project, a first step toward IODP, aimed to recover comprehensive transects across continental margins to reconstruct sedimentary processes and past global changes on two deltaic margins, the Gulf of Lions and the Adriatic. (2) Producing 3D mapping of key areas off the Rhone delta, on sites where sedimentary processes are believed to be particularly active. This investigation was intended to complement studies in the deltaic area by CEREGE (M. Provansal, C. Vella, et al.) and in the coastal zone (CEFREM, M. Tesson et al.). It was part of the French Margin Project, and of the new EU-funded EUROSTRATAFORM project. (3) Vibro-coring of "offshore sands" on the outer shelf; (4) Percussion coring of cemented sands that represent a "dipstick" of past sea-level changes in the area. (5) Detailed mapping of zones selected as potential sites for artificial reefs. This project was supported by the Languedoc Roussillon regional council. The bathymetric survey with the MBES EM 1000 was of poor quality due to bad weather conditions. The other sensors gave satisfying results. This falls under the IFREMERR 'DefiMarges'. |
