ADCP Application:
ADCP uses sound waves to measure the speed and direction at which water moves across an entire water column. An ADCP will transmit constant (high) frequency pulses of sound which scatter off of moving particles in the water. Measured frequencies of return signal will vary based on the direction of water flow. These pulses extend to the bottom of the ocean and as such, an ADCP measures current speed and direction at many different depths simultaneously.ADCPs use acoustic transducers which emit and receive acoustic pulses from different directions. Trigonometric relations allow for the derivation of current direction; each transducer represents cardinal direction on a coordinate plane (north-south, east-west, and up-down).
