GEOFLAMME cruise - Underwater photo of an Ocean-Bottom Seismometers (OBS) on the seafloor
During the 2021 cruise of the Geochemistry, Fluids, Acoustic Anomalies, and Magmatic Activity Following the Mayotte Eruption (GEOFLAMME) program, the Institut Français de Recherche pour l'Exploitation de la Mer’s Victor 6000 remotely operated vehicle took this photo of one of the OBSs (Ocean-Bottom Seismometers) deployed with the ballast cage during the MAYOBS 18 cruise. The OBS was found within about 5 meters of where it was expected on the basis of the position provided by the USBL system (ultrashort baseline acoustic positioning system).
