"Side Scan Sonar" (continued)
Side scan sonar technology provides high resolution, almost photographic quality imagery of the seafloor. It is commonly used in industry to locate pipeline or cable routes, and to search out small but specific objects that need to be found, such as shipwrecks, mines, or downed aircraft. Side scan sonar is sensitive enough to measure features smaller than 10 cm (less than 4 inches) on the seafloor. It is also good to use when accurate maps of large sections of seabed are needed.
