  • 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.

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

  • 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.

  • 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.

  • The AMORGOS-23 cruise (https://doi.org/10.17600/18003211) was conducted onboard R/V Europe from April 26th 2023 to May 9th 2023. Using HROV Ariane equipped with 4K cameras, we surveyed the main active faults between Amorgos and Anafi islands in order to identify and quantify recent deformation of the seafloor linked to the 1956 Amorgos earthquake. During dive 244-1, we surveyed the steepest scarp of the Amorgos fault, along its central segment. We provide here seven scaled Digital Outcrop Models (in .obj format) calculated from the HROV videos with MATISSE 3D software. There location (model origin) is also provided in a table, together with information about the portions of the videos used to produce the models. Due to incomplete navigation data, the models are not properly oriented.

  • 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.

  • Near-bottom multibeam bathymetry and back-scatter data acquired along the Amorgos and Santorini-Amorgos faults, in the Aegean sea. High-resolution bathymetry data (1 m/pixel) were acquired by the autonomous underwater vehicle (AUV) IdefX, deployed during the AMORGOS-22 cruise (https://doi.org/10.17600/18001479) with the MBES EM2040. The dataset consists of six DEMs as well as fourteen back-scatter mosaics (i.e. two versions for each dives, raw and processed (compention of the antenna diagram)). In addition, a DEM extracted from dive 2 is provided. The bathymetric data were processed with GLOBE, while the back-scatter data were processed with Sonarscope. Renavigation of the vehicule was necessary during processing and is applied to both the bathymetric grids and backscatter mosaics. Files are provided in TIF format, projected in UTM 35 N (WGS 84).
