Definition A type of current meter capable of simultaneous measurement of current velocity at a number of different depths based on determining Doppler shift of transmitted sound. Instrument mounted on a moving platform such that the signal is transmitted downwards toward the seabed. Note that unless the ship is firmly anchored currents are not measured directly and need to be computed by differencing ship's velocities relative to land and water.
