Bathymetry - Indian Ocean, transits (ECOLE BLEUE OUTREMER cruise, 2022)

Bathymetry along vessel transits, between La Réunion and Mayotte, Indian Ocean (ECOLE BLEUE OUTREMER cruise, 2022), at 100 meters cell size. This dataset is a Digital Terrain Model (DTM), derived from the acoustic acquisitions of the multibeam echosounders EM122 (12kHz) and EM710 (100kHz) of the Marion Dufresne. The backscatter intensity of the acoustic signal is also available, averaged per pixel, without any additional processing.
