The acoustic Doppler current profiling system at AOML
OCEANS '88. 'A Partnership of Marine Interests'. Proceedings, 2003The design and performance of the data acquisition and logging system of the acoustic Doppler current profiler on the NOAA ship Malcolm Baldrige are described. The accuracy of the absolute current measurements is limited by the ability to determine ship movement and orientation.

Water profile navigation with an Acoustic Doppler Current Profiler
OCEANS'10 IEEE SYDNEY, 2010A novel navigation method is introduced using water current profiles measured by an Acoustic Doppler Current Profiler (ADCP) mounted on a moving vehicle. These current profiles are combined with measurements of vehicle attitude and depth to simultaneously estimate the local current and the vehicle velocity.

Backscattered intensity profiles from horizontal Acoustic Doppler Current Profilers
2010Horizontal Acoustic Doppler Current Profilers (HADCPs) are a relatively new instrument that can be used to measure cross-river profiles of streamwise velocity and may also provide a relative measure of particle concentration. A number of these instruments are currently installed along three French rivers at locations intermediate to power plants and ...

Deep ocean current profiling with a lowered broadband acoustic Doppler current profiler
Proceedings of OCEANS'94, 2002An RD Instruments 150 kHz Broadband Acoustic Doppler Current Profiler (ADCP) has been mounted on a CTD frame and used to measure current velocity shear below the instrument during casts as deep as 5500 meters. By using processing techniques similar to those described by Firing and Gordon (1990) for a 300 kHz narrowband ADCP and Fischer and Visbeck ...

Shipboard acoustic doppler current profiler surveys to assess tidal current resources
OCEANS 2010 MTS/IEEE SEATTLE, 2010A compelling aspect of power generation from tidal currents is the predictability of the resource, which is generated by the gravitational pull of the sun and moon on the earth's oceans. For technical feasibility studies, it is presupposed that once the currents at a site have been well characterized it is possible to make accurate predictions of the ...

38 kHz broadband phased array acoustic Doppler current profiler
Proceedings of the IEEE Fifth Working Conference on Current Measurement, 2002Recently RD Instruments (RDI) finished developing and demonstrating the performance of a prototype 38 kHz broadband phased array acoustic Doppler current profiler (ADCP) for deep ocean current measurement. Unlike conventional RDI ADCPs with four circular transducers, the prototype uses one flat face broadband phased array which is about the same size ...

Measuring the Dispersion Coefficient with Acoustic Doppler Current Profilers
Journal of Hydraulic Engineering, 2007A method is evaluated for estimating the longitudinal dispersion coefficient K from velocities and bathymetry measured with an acoustic Doppler current profiler (ADCP). If shear dispersion controls the mixing, the dispersion coefficient can be estimated from measurements of velocity and depth in a cross section. The dispersion coefficient has typically

Horizontal acoustic doppler current profile instrument development and applications
Proceedings of the IEEE/OES Seventh Working Conference on Current Measurement Technology, 2003., 2004RD Instruments Inc, USA, (RDI) commercially developed the Broadband Acoustic Doppler Current Profiler (ADCP) in the early 1980s and has delivered more than 3500 instruments to over 50 countries, during the last 20 years. While vertical profiling from a fixed or moving platform is considered to be a standard application technique, horizontal profiling ...

Backscatter estimation using Broadband acoustic Doppler current profilers
Proceedings of the IEEE Sixth Working Conference on Current Measurement (Cat. No.99CH36331), 1999Growing interest has developed in acoustic studies about the abundance and distributional patterns of the suspended matter, such as plankton and sediments, that act as sound scatterers for Broadband acoustic Doppler current profiler measurements. Supported by careful calibration procedures, acoustic studies using vertical profiles of echo intensity ...
