Attention:

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

Summary
