Acoustic Doppler Current Profiler

An Acoustic Doppler Current Profiler (ADCP) is a device used to measure water currents in rivers, lakes, and oceans. It emits sound waves that bounce off particles in the water. By analyzing how these sound waves change in frequency as they reflect back—due to the Doppler effect—scientists can determine the speed and direction of the water flow at various depths. This information is crucial for understanding aquatic environments, navigation, and managing water resources. ADCPs are commonly used in environmental studies, hydrology, and fisheries research.
