ADCP

ADCP’s are velocity profilers that use acoustics to measure 3D water-current velocity for a small volume of the water column above or below the sensor. High frequency sound waves (75- to 600-kHz) emitted by the profiler scatter off suspended particles and back to the sensor. The sensor calculates velocity by measuring changes in these sound waves (i.e., Doppler shifts).
