Measurements of fish school velocities with an acoustic Doppler current profiler
Abstract: Horizontal and vertical velocities of fish schools were measured using an acoustic ... Doppler current profiler (ADCP). To determine three orthogonal velocity vectors (east, north, and vertical ... ), it was required that the four ADCP beams simultaneously insonified a fish school, in the same depth bin. Velocity ... school velocities with an acoustic Doppler current profiler Approval: Approved ...
