NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the sea floor such as shipwrecks, and map the sea floor itself. There are two types of sonarâactive and passive.
We are using the DSL-120 kHz side-scan sonar instrument to map the surface of the Puna Ridge.The DSL-120 vehicle is towed 100 m (300 ft) above the seafloor. Sound is transmitted into the water by the side-scan sonar instrument at an angle rather than just straight down as shown.The sound transmitted by the DSL-120 kHz instrument travels to the seafloor, bounces off of the seafloor, returns to the instrument, and is recorded.o the right is the side-scan sonar image of the same volcano illuminated from the right. Notice that the volcano casts a shadow to the left, and the slope facing to the right is very bright. Smaller bumps also cast small shadows making the topography look lumpy. Each image is 3 km (1.8 miles) wide.
