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
MIDAS Sound Velocity Profiler is used for measuring the speed along a vertical transect through the water column up to 6000m water depth. Two identical Valeport MIDAS probes exist on RV Polarstern, the second probe with serial number SN34079 serving as backup for SN41492.

Components
The sound velocity probe consits of the probe, the mounting cage and the computer. The data processing software DataLog Express is installed on the computer. RS232 interface connects the computer to the probe. The sound velocity profiles can be transferred to the computer of the multibeam echo sounder Hydrosweep DS3 via the computer network.
Two Valeport MIDAS exist on RV Polarstern and are used alongside without further discrimination.
