Here we present the development of a short range (0.5 to 20 m), low cost (< USD 5,000), three-beam, 1 MHz acoustic Doppler current profiler called the Nortek ECO. The system employs a robust wideband velocity measurement technique where the only requ

Recognizing that detailed analyses of the accuracy of acoustic current profiles from instruments mounted on dynamic surface platforms (MetOcean or wave buoys) were lacking, the authors and colleagues began studying the issue in 2014. Initial testing

Since the early 2000s, long range (> 600 m) Acoustic Doppler Current Profilers (ADCPs) have been widely used in the Gulf of Mexico in connection with the Oil and Gas industry. These ADCPs have been mounted almost exclusively on large, stable offshore

Improvements to motion compensation in current profile data from surface buoys have been previously presented [1] and here we expand on this previous work on the integration of Attitude and Heading Reference Sensors (AHRS) to Acoustic Doppler Current

A sea surface following buoy equipped with a wave sensor and acoustic Doppler current profiler (ADCP) may be a useful system design option for many different coastal ocean measurement applications. However, previous work has shown that surface buoy-m

Oceanographic current profiles measured using acoustic doppler current profilers (ADCPs) can be made using surface buoy, subsurface and seabed mounting arrangements. Buoy-mounted ADCPs offer several distinct advantages compared to subsurface and seab

The present work describes a newly-developed Acoustic Doppler Current Profiler (ADCP) that has a fully integrated single-beam wide-band biological echosounder, thus serving a dual purpose: current measurement and biomass assessment. The system compri

The present work focuses on improving motion compensation in current profile data from surface buoys by integration of an Attitude and Heading Reference Sensor (AHRS) to a state-of-the-art Acoustic Doppler Current Profiler (ADCP), thus expanding its
