Side-scan sonar is a remote sensing device that uses sound waves to create detailed images of the seafloor. It is commonly mounted on a towfish, which is towed behind a vessel at a constant distance from the seabed. As the towfish moves, it emits sound waves that are reflected back to the receiver on the device. By analyzing the time it takes for the sound waves to return and their intensity, side-scan sonar creates high-resolution images of the seafloor., H, O i- L" L* | r

Sediments can range from fine silt and clay to coarse sand and gravel, and their distribution can provide critical information about the sediment transport processes in the area. By observing the patterns and textures of sediments, experts can gain insights into the currents, waves, and other factors affecting the sedimentation on the seafloor./ w0 ^# w2 h* h0 p" ~6 X

Furthermore, side-scan sonar enables the detection of submerged structures, such as shipwrecks, pipelines, cables, reefs, and even archaeological sites. These structures can have considerable implications for navigation safety, environmental management, and historical research. The high-resolution imagery produced by the side-scan sonar facilitates the identification and assessment of such features, aiding in their preservation and potential utilization.

By interpreting the shape, size, and spatial arrangement of underwater landforms such as channels, canyons, ridges, and valleys, geologists can reconstruct the geological history and identify the forces that shaped the seabed. This information is crucial for assessing geohazards, evaluating natural resource potential, and planning marine infrastructure development.
