|---|
|
The sound velocity transducer is used for measuring the speed of sound in the water at ship's keel. The data are used for Parasound and Hydrosweep operationSVP 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. |
