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. |
...
The Valeport Mini SVP is permanently integrated and operates autonomously. |

|
The Valeport miniSVS Sound Velocity Sensor provides high resolution, high accuracy sound velocity data. The basic principle is “time of flight”; that is to say, the sound velocity is calculated from the time taken for a single pulse of sound to travel a known distance. |

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. |

The sound velocity probe measures the sound velocity in temporally equidistant intervals and stores the data to the internal flash drive. Import of the data from the probe to the computer is conducted with the data processing software DataLog Express. There is no designated central sound velocity data storage location. The opterator is in charge of sound velocity data storage for further use, e.g. data transfer to the multibeam echo sounder Hydrosweep DS3. |

Multibeam
Valeport MiniSVS can be selected in Multibeam Echo Sounder control software SIS to be source of c-keel value. If so and raw data logging of multibeam echo sounder is switched on, c-keel value is stored in Simrad Processing File of type *.all
