Explore: Echo Sounding

Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water (bathymetry). It involves transmitting acoustic

Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps

processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional

of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines. Echo sounding, listening to the echo of sound pulses
