Please note that operations of the Acoustic Doppler Current Profiler requires experienced scientific staff on board. The system is not operated by the ship's crew. Announce operations with the Acoustic Doppler Current Profiler to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise.

Summary

The Acoustic Doppler Current Profiler (ADCP) measures flow rates in the water body below the moving vessel with an operating frequency of 150 kHz. Up to 400m range can be achieved according to the data sheet.
