Abstract Work carried out during this project improved our ability to link SAS image statistics to measurable environmental properties such as seafloor roughness. During the course of this project we: (1) Examined relationships of acoustic scattering properties to SAS means levels and statistics; (2) Developed predictive physics-based forward models of mean levels and statistics relevant to SAS; (3) Developed inversion tools for estimating seafloor properties based on forward models; and (4) Validated forward models and inversion results against at-sea experimental data.
