WitrynaAn acoustic Doppler current profiler (ADCP) is used to measure movement in the water, both as waves and currents. ADCPs are often anchored to the seafloor (Fig. 5) to measure waves and currents in the whole water column, or mounted horizontally to measure the waves and currents across rivers and channels. An ADCP measures … WitrynaAn ADCP doubles the Doppler effect because it works between the ADCP and the reflectors in the water, and then again after the sound is reflected back to the ADCP. Doppler Velocity Log Often abbreviated DVL, this is a special type of ADCP whose primary function is to measure an underwater vehicle’s speed and direction over the …
