Liquid Robotics, Inc. (LRI) has developed an autonomous vehicle, the Wave Glider®, which utilizes wave energy for propulsion, Iridium® Satellite for command, control and data exfiltration and GPS satellite transmissions for positioning. The vehicle consists of a low-profile surface float outfitted with solar panels, energy storage and shore communication infrastructure and a subsurface wing located...
Summary form only given. A new horizontal profiling ADCP achieves 1 cm/s velocity standard deviation with 2 second averaging interval. The results of data from several locations are discussed and the performance of this instrument is discussed in detail. The results show that this instrument offers the ability to measure very low velocities in near real-time, allowing high spatial and temporal resolution...
A new acoustic Doppler current profiler (ADCP) for general purpose current measurements in water depths less than 200 meters is described. RD Instruments Workhorse series features two 300 kHz profilers: the Monitor model requires a power source and provides real time data; Sentinel is battery operated and records data. Their application in ports and harbours, coasts, and deep sea are described.
