GraviMob-1 campaign is an underwater gravimetric survey conducted near the southern coast of France in the Mediterranean Sea in March 2016. The AUV Asterx was used to carry the GraviMob system. The operation was performed on board the vessel Europe. The data and processing results of this campaign are supporting the paper "High-resolution gravity measurement on board an Autonomous Underwater Vehicle: Data reduction and accuracy assessment". The dataset thus contains the following elements: 1. The raw data exported from GraviMob 2. The shipborne gravity data provided by SHOM 3. The processing results

These bathymetric data were produced using the interferometric side-scan sonar onboard the Haliotis Research Vessel, Operated by Genavir, for the French Oceanographic Fleet, in October 2022, during the oceanographic campaign HISOPE (l'Haliotis pour l’Imagerie Sismique d’Orbetello et Pyrgi Etrusques). The investigated area is located in front of the tombolo di Feniglia, in the Gulf of Porto Ercole. The goal of the campaign was to image the sedimentary architecture of the Tombolo di Feniglia Acquisition took place from October 1st to October 6th 2022. Data were acquired by eng. Quentin Layahe, Genavir, onboard the Haliotis, piloted by Serge Garcia, and post-processed using the software Globe, developed by the IFREMER, by Dr.Gilles Brocard (Archéorient, University of Lyon 2, France) and Alessandro Conforti, research engineer at the CNR (Italian national center for research) at Orosi, Sardinia.

Multibeam bathymetry acquired during SWIFT cruise with the Marion Dufresne. Processed data gridded at 100 m and provided in NETCDF GMT format (.grd extension).

The following data were acquired in 2013 by the french research vessel N/O Suroit during the CIRCEE cruise (see the cruise report): - High-resolution 72-trace seismic data. The files are available in the segy format. A map is provided to locate the 1500 km of seismic profile acquired. - Gridded bathymetry data (resolution : 90m) available in GRD format (software GMT Generic Mapping Software de Wessel & Smith based on NetCDF libraries). A map is available. - Bathymetry data from multibeam echo sounder Kongsberg-Simrad EM302. The data are available in the raw data mbg and include the travel time and amplitude (reflectivity). - Highfrequency chirp-sonar data. The files are available in the segy format. A map is available in the cruise report.

Photomosaics acquired by  ROV Victor during dives #653, #654, #655, and #658, along the Roseau Fault (French Antilles).  The images, acquired with the ROV vertical camera, were positioned and scales using ROV navigation only (no feature matching, renavigation and reprojection). Images are corrected for uneven illumination. Photomosaics are presented in folders for each dive, and include a Geotiff (.tif) and a location file (.tfw). All photomosaics are in projection WGS84 UTM 20N.

Multibeam bathymetry data, gridded at ~100m, acquired around during the transit towards the Mid-Atlantic ridge axis (13°20'N and 13°30'N oceanic detachments area) during the ODEMAR cruise (2013). Bathymetric data was acquired by the PourQUoi Pas? multibeam system (RESON SEABAT 7150).

Photomosaics acquired by ROV Victor during ODEMAR cruise, Dive #563, with OTUS camera (B&W) vertically mounted. Track follows the Roseau Fault (French Antilles, off Les Saintes islands). GEOTIFFS projected in WGS84 UTM Zone 20N.  

Multibeam bathymetry acquired by AUV Abyss (GEOMAR), during the ODEMAR Cruise off Les Saintes ilsnads (French Antilles). Data is processed and gridded at 2 m resolution.

Near-bottom multibeam bathymetry and acoustic backscatter acquired at the Rainbow Massif  (Mid-Atlantic Ridge). High-resolution bathymetry data (2 m/pixel) were acquired by the autonomous  underwater vehicle (AUV) IdefX, deployed during the ARC-EN-SUB (https://doi.org/10.17600/18000663)  cruise in May 2022. The dataset consists of grids for each individual AUV dive, as well as a global grid merging the ten completed dives. This global grid was obtained by manually shifting and combining original bathymetric grids of each dive using other datasets (primarily shipboard bathymetry from Paulatto et al. [2015]) for geographical reference. The combined grid shows the inter-dive shift artefacts, absent in the individual dive grids. Elevation grids are provided for each AUV dive without interpolation (fillgap 0), with medium (fillgap 3) and high (fillgap 15) interpolation.Acoustic backscatter grids are edited without interpolation (fillgap 0). All grids are provided in NETCDF GMT .grd format, and with two associated GEOTIFFS with the bathymetry DEM, the acoustic backscatter, and the hillshade (illumination) file.  All grids are given in WGS84 (WGS 84 - WGS84 - EPSG:4326), in projection Mercator.

This dataset contains seismic data from 17 OBS collected in the equatorial Atlantic Ocean during the SMARTIES cruise in 2019. 12 OBSs are located along the eastern Romanche transform and fracture zone, and 5 OBSs are located along the Mid-Atlantic Ridge. The OBS data are vertical components and recorded in MiniSEED format. The data collection started from 2019-07-20T00:00:00 to 2019-08-16T24:00:00. This dateset includes raw data from OBS #10 to OBS#19. OBS#15 recorded no data. Data from OBS#1 to OBS#9 are available from a companion dataset. OBS#8 was lost.
