Raw singlebeam echosounder data from the French civil Research vessels, archived at SISMER (IFREMER)

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 (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.

Bathymetric model (DTM) of the Mediterranean. MediMap group. Bathymetry data acquired by multibeam sounders during campaigns Almofront.leg1 and Almofront.leg2, Almofront, Bretane, Seamewe2, Heralis, Medee, Anaxiprobe, Almofront2 - leg1 and leg2, Prismed2, Marmara, Fanil, Tvic5 et 6, Progres, Maradja, Blac, Nautinil, Medor-Simed1 / 2 / 3 / 4 / 5, Maradja2, Sardinia, Prisme, Assemblage and Thertou. Integration of partner organizations DTM. This DTM is available at two cell sizes : 500 m and 1000 m.

Bathymetric and topographic model of the island of La Réunion. Topography is from IGN data. Bathymetry is derived from the multibeam data acquired during the campaigns Forever (2006, EM12D sounder) Eroder1 (2006, EM120 sounder) and Eroder2 (2007, EM120 sounder). The grid spacing is 300m.

EM12 and EM 950 surveys + gravimetry, magnetism and rapid digital seismics to study the mechanism of the ocean ridge's propagation from the Gulf of Aden towards the west(gulf of Tadjoura and Ghoubbet).

Bathymetry of the French Guiana margin: the digital terrain model results from data compilation of 3 multibeam surveys conducted on the French research vessel RV L’Atalante. Grid resolution is 250 m. The DTM was processed as part of the French national program (EXTRAPLAC) for the delineation of the outer limit of the continental shelf beyond 200 nautical miles. - Guyaplac, 2003, R/V Atalante: Main source of the DTM was a cruise funded by the French National programme EXTRAPLAC. https://doi.org/10.17600/3010050 - Lobestory, 2004, R/V L'Atalante, https://doi.org/10.17600/4010030 - Cither1, 1993, R/V L'Atalante, https://doi.org/10.17600/93000010

Acquirement of multibim bathymetric datas along the south-west indian ridge between 57°E ans the Rodrigues triple junction.

Bathymetry of the Congo fan (synthesis, 2013), with a spatial resolution of 100 meters (WGS84 / Mercator 5°30'S). This dataset is a compilation of bathymetric data from several cruises.
