Rowe EDU - ADCP Applications Summary
General Acoustic Doppler Current Profilers (ADCP) are hydro-acoustic instruments that are used to measure water velocities or currents over a specific range of water depth. ADCPs utilizes the Doppler effect to measure water velocity in discrete layers – essentially sending a sound signal of a specific frequency into the water column and measuring the sound signal return. The change in return frequency is proportional to the water velocity. ADCPs can be deployed in many ways, up-looking, down-looking, and side-looking.
