Research abstract

THE PROPOSAL DEALS WITH TESTING A NEW TYPE OF DOPPLER ACOUSTIC CURRENT PROFILER FOR MEASUREMENT OF PROFILES OF WATER VELOCITY. THIS NEW PROFILER MEASURES VELOCITY TRANSVERSELY TO A MAIN ACOUSTIC BEAM AND FEATURES MEASUREMENTS FROM A SINGLE SCATTERING VOLUME. CONSEQUENTLY, THIS TRANSVERSE DOPPLER PROFILER FEATURES REDUCED SENSITIVITY TO FLOW INHOMOGENEITIES AND IMMUNITY TO DEAD ZONES CAUSED BY SIDE LOBE REFLECTIONS. THE CAPABILITIES OF GENERAL OCEANICS FOR MAKING LIMITED PRODUCTION OCEANOGRAPHIC INSTRUMENTATION WILL BE USED TO CONSTRUCT A TRANSVERSE DOPPLER PROFILER INSTRUMENT THAT WILL BE USED TO INVESTIGATE THE CAPABILITIES OF THIS TYPE OF INSTRUMENT. IN ADDITION TO MEASURING VELOCITY PROFILES, PROPER SIGNAL PROCESSING ALGORITHMS WILL ENABLE A TRANSVERSE DOPPLER INSTRUMENT TO MEASURE PROFILES OF TURBULENT FLUCTUATIONS AND HENCE REYNOLD'S STRESSES. CONTROLLED ELECTRICAL OR MECHANICAL MOTION OF THE TRANSDUCERS WILL ALLOW MEASUREMENT OF TEMPERATURE AND SALINITY PROFILES.
