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.


  • 400 kHz version of the AWAC
  • ProLog Internal Processor
  • Special ice detection algorithm
  • Improved pressure sensor
  • SeaState 2.0 for online data collection

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.
