For some years now, autonomous vehicles achieve more and more hydrographic survey operations. Their fields of action are becoming more extended and they allow reducing the costs of this type of intervention in comparison with conventional survey...

Rapid technical advancement has seen a move away from more traditional methods of sub- sea operations, such as the use of divers, in favour of using unmanned and remote vehicles. Remotely Operated Vehicles (ROVs) are now being extensively used in...

During several expedition seasons, starting from 2003, TRD Instruments- Europe provided us with ADCP Workhouse “Rio Grander 600 kHz” gratuitously supporting our studies at shelves of Russian seas. The first studies showed that the instrument...

Woods Hole Group Inc. (formerly Horizon Marine, Inc. (HMI)) provides oceanographic services specifically tailored to the offshore energy industry. Our services are designed to assist with planning safe and efficient operations to minimize costly...

This presentation will discuss how ADCPs on Wave Gliders provide a viable and flexible way to get critical upper-ocean current data. ADCPs on Wave Gliders provide a more efficient way to get key oceanographic data. Operating unmanned vehicle is...

The Liquid Robotics Wave Glider has demonstrated great success as a host platform for acoustic modems. Numerous customer missions have employed these systems to provide seafloor to surface connectivity. In this presentation recent results will be...

Acoustic instruments and methods for streamflow measurements first began to be integrated into the USGS streamgaging program in 1992, shortly after the TRDI Broadband Acoustic Doppler Current Profiler (ADCP) was released. Although these...
