To this end, we used multibeam echosounder data to generate metrics that describe the seafloor: backscatter strength at normal and oblique incidence angles, the variation of the angle-dependent backscatter strength within 10[degrees] of normal incidence, the scintillation of the acoustic intensity scattered from the seafloor, and the seafloor rugosity.
