Attention:

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

Summary

SVP is meant to be installed in RV Polarstern box keel at depth of 11m. Measurement data are primarily used as c-keel values for echo sounder systems Parasound and Hydrosweep.
