The field tests took place in 2023 and 2024 in the Chesapeake Bay near the Chesapeake Bay Bridge and Tunnel. The data set also includes measurements from an Acoustic Wave and Current profiler that was used as a reference. The AWAC was located on the seafloor at approximately 16 m depth at 37.0334N and 76.0836W. The radar was located on the bridge at a height of 8-10m, 37.0315N and 76.0853W. The Sofar buoys were moored at 37.0341N and 76.0856W. These datasets have not been quality controlled and should only be used to study the performance of the sensors. They are not intended to be used outside of this scope. This data was collected as part of a field test of the instrumentation themselves. They have not been quality controlled and should only be used to study the performance of the sensors.

NOAA National Centers for Environmental Information custodian Acoustic Wave and Current Profiler (AWAC) Acoustic Wave and Current Profiler (AWAC) The Acoustic Wave and Current profiler (AWAC) performs measurement of wave height, wave direction and the full current profile using the unique acoustic surface tracking (AST) feature. The system can resolve waves from 1 to 100 s. AWAC provides current profiler and a wave directional system in one unit. AWAC can measure the current speed and direction in 1-meter thick layers from the bottom to the surface. Possible as powered from network also as stand-alone, as bottom moored or mounted on subsurface buoys. Wave direction is calculated by combining AST with orbital velocity measurements in an array near the surface. buoy - drifting buoy buoy - drifting buoy buoy - drifting buoy radar - high frequency oceanographic radar - high frequency oceanographic http://ifmaxp1.ifm.uni-hamburg.de/WERA.shtml
