Seafloor acoustic backscatter – Mayotte (MAYOBS23 cruise, 2022)

Acoustic backscatter from the seabed east of Mayotte (MAYOBS23 campaign, 2022), at 50-meter cell size. This data set comes from the acoustic acquisition of the EM122 multibeam sounder (12kHz) from the Marion Dufresne. Backscatter intensity is expressed in relative decibels (dB), without absolute reference (no calibration). Processing report: Pierre Delphine, Gaillot Arnaud, Perret Tyméa (2022). Mission MAYOBS23.
