WebMar 16, 2011 · Measuring how fast water is moving. An Acoustic Doppler Current Profiler ( ADCP) is used to measure how fast water is moving.An ADCP anchored to the seafloor can measure current speed not just at the bottom, but also at equal intervals all the way up to the surface. The ADCP works by transmitting "pings" of sound at a constant frequency … WebCollecting bathymetry with sonars in the marine environment means measuring the path and travel distance of sound from the transmit point, to the seabed, and back again to the receive point. Refraction occurs when the speed of a wave changes due to a change in medium in which the wave is traveling through.
