Acoustic doppler current profiling from a volunteer commercial ship
Proceedings of the 1986 IEEE Third Working Conference on Current Measurement, 2005An acoustic Doppler current profiler has been successfully installed on a volunteer commercial ship, the 42,000 DWT oil tanker EXXON Jamestown, which makes monthly round trips from Houston, Texas to Santa Barbara, California via the Panama Canal. Doppler current data collected by the Jamestown so far indicate that the system noise levels are low and ...

A Towed Acoustic Doppler Current Profiler System.
1996Abstract : This grant covered the cost of acquiring a complete towed ADCP/CTD system, assembling it and doing preliminary tests. The system has subsequently been used very successfully as part of the ONR-funded program 'A Towed Acoustic Doppler Current Profiler System,' to collect upper ocean profiles of current in the data scarce eastern Indonesian ...

Results of a horizontally mounted acoustic Doppler current profiler
IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002Shallow, narrow and busy channels do not easily allow conventional current measurements in real time. The goal is to investigate the possibility of using data of a horizontally mounted ADCP for measuring flow velocity and direction in a river or channel.

Theoretical Accuracy of Doppler Navigation Sonars and Acoustic Doppler Current Profilers
IEEE Journal of Oceanic Engineering, 2004This paper addresses the problem of Doppler shift estimation in Doppler sonar systems. The analysis focuses on the single-beam geometry formed by a circular planar array and considers both narrow-band (or so-called incoherent) and wide-band (or coherent) Doppler sonars, transmitting, respectively, one long continuous-wave pulse and a train of short ...

Acoustic Doppler Current Profiler (ADCP) Measurements of Breaking Waves
Volume 2: Fora, 2008Detailed flow measurements of the turbulent multiphase flow associated with wave breaking present a unique instrumentation challenge. Measurement systems must be capable of high sampling rates, large dynamic ranges, and be capable of making measurements in water, air and optically opaque regions. An experiment was performed at the Naval Surface Warfare

Continental Shelf Broadband Acoustic Doppler Current Profiler Facility.
1998Abstract : The following instruments were purchased from RD Instruments (RDI): six (6) 300 kHz Workhorse Sentinel Broadband Acoustic Doppler Current Profilers (ADCP's); one: (1) 150 kHz Broadband Acoustic Doppler Current Profiler; and two (2) accessory battery packs. These instruments were deployed repeatedly in support of the ONR-sponsored research of

Collection and Analysis of Acoustic Doppler Current Profiler Data
1996Abstract : Acoustic Doppler Current Profilers are presently employed by the U.S. Army in a number of projects. However, as with most new techniques there have been several problems both with the collection and the subsequent analysis of data. The main objective of this work is to improve the accuracy of Acoustic Doppler Current Profilers by examining ...

Optimizing acoustic doppler current profiler settings for noise reduction
Proceedings of the IEEE/OES Seventh Working Conference on Current Measurement Technology, 2003., 2004The performance of a 600-kHz broadband Acoustic Doppler Current Profiler (ADCP) developed by RD Instruments (RDI) is evaluated to determine the optimum settings for minimizing random noise associated with the inherent single-ping uncertainty in the instrument.
