Attention:
Please note that operations of the GPS Wave Buoys (GPS Waverider) require experienced scientific staff on board. The system is not operated by the ship's crew. Announce operations with the system to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise.
Summary
The directional waverider DWG-G4 measures wave motion, height and direction. Temperature may also be obtained. The waverider is deployed when needed. The antenna is fixed installed in the upper mast platform. The receiver and operation laptop running software SeaSaw 21 are positioned in aerologie lab A-112.
