Towed current profilers: Mapping currents in channels and fjords

Keywords: velocity, instrumentation, doppler, acoustic, current, Profiler


Over the past decade, acoustic current profiling instruments have proven to be a powerful tool in measuring currents in the ocean, obtaining direction and magnitude of currents in a vertical profile. These instruments use high frequency acoustic backscatter and the Doppler principle to obtain detailed measurements of current velocity profiles. Suspended particles carried by currents in the water produce echoes that are 'listened to' by the current profilers in order to obtain current magnitude and direction.
