ADVANTAGES Sound NAvigation and Ranging—SONAR—is used to find and identify objects in water. It is also used determine water depth (bathymetry). Sonar is applied to water-based activities because sound waves attenuate (taper off) less in water as they travel than do radar and light waves. Sonar was first used during World War I to detect submarines. By the 1920s, the U.S. Coast and Geodetic Survey—the precursor to NOAA’s National Ocean Service—was using it to map… Read More

Sonar, RADAR and satellites and space travel improved the accuracy of maps after World War 2.
Sonar helped map the ocean floor
It evolved out of research and development into sound-detection devices used to locate and for navigation and countermeasures, on- Submarines, usually called SONAR. Sound navigation and ranging. A sonic altimeter was developed for Blimps in the Twenties and could also detect submarines, as Blimps were employed in the anti-sub war role in World War II.
