A three-minute video about multibeam and side scan sonar, including a visualization that shows how sonar data is used to make products like nautical charts. Download : Soundscapes 75 MB. Sonar, short for Sound Navigation and Ranging , is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. NOAA scientists primarily use sonar to develop nautical charts , locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself. There are two types of sonar—active and passive. Active sonar transducers emit an acoustic signal or pulse of sound into the water.
