The mapping of seafloor topography has been largely relying on standard hydrographic echosounders. Sounds propagate effectively in seawater. Their natures are well recognized and become the basis of knowledge in the design of underwater surveys’ technology. With that, sonar devices (including echosounders) are hence developed and fortified with specific features for different purposes. The depth…
