This bathymetric data package is being made available as part of the de-risking study to be carried out in the Gulf of Lion for the award of a "commercial floating wind turbine" call for tenders by 2022. It includes bathymetric digital models covering French territorial waters. Raw data have been acquired during oceanographic campaigns: AM-MED-1, BASAR2, BASAR3, RHOSOS et STRATAFORM 1.

Reconnaissance geophysique, geologique, petrographique et geochimique systematique du point triple de Rodriguez ou convergent trois dorsales medio-oceanique. Exploration geophysique, geologique, petrographiqueet geochimique d'un segment de la zone axiale de chacune des trois dorsales. Reconnaissance, dans le bassin de Wharton, d'une dorsale fossile.

Geophysical and geochemical study of the Pacific-Antarctic ridge between S65/W175 and S60/W150. The first objective was to contribute to the understanding and modelling of the mechanisms of ocean ridge functioning on the scale of the basic accretion unit (< 100 km). The second was to study the zoning of the upper mantle on various scales, through investigating the geochemical signature of rocks from the axial valley. This cruise falls under the framework of the Inter-Ridge programme and is the result of cooperation between IFREMER/DRO/GM, INSU (CNRS,IPG, GRGS), Washington State University, Scripps (University of California) and the University of Chiba (Japan).

Geophysical (bathymetry, gravimetry, magnetism, seismics and multichannel reflection) and geological (dredging) studies of the northern part of the Kerguelen plateau (Indian Ocean). Survey of ODP drilling sites (leg 183). The Kerguelen underwater plateau is still puzzling today, when trying to understand its origin and explain the way it was formed. To try to answer these questions, new deep ocean drilling was to be done on the Kerguelen shelf in late 1998 and early 1999.
