Seafloor acoustic backscatter - Mayotte, AUV dive 459-05 (MAYOBS23 cruise, 2022)

Acoustic backscatter from the seabed of dive 459-05 east of Mayotte (MAYOBS23 campaign, 2022), at 1 meter intervals. This dataset comes from the acoustic acquisition of the EM2040 multibeam sounder of the AUV AsterX (300kHz). Backscatter intensity is expressed as relative decibels (dB), without absolute calibration. Navigation processing level: Navigation readjusted with the EM122 bathymetry of the Mayobs23 coastal zone as a reference Processing report: Pierre Delphine, Gaillot Arnaud, Perret Tyméa (2022).
