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. |

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. |

The sound velocity probe consits of the probe, the mounting cage and the computer.
The data acquisition and 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 https://spaces.awi.de/confluence/pages/viewpage.action?pageId=182353956 via the computer network. |

Die Wasserschallprofilsonde (SVP) misst bzw. berechnet zeitlich äqudistant die Wasserschallgeschwindigkeit und speichert diese im interne Flash-Speicher ab. Mittels PC-Software wird das Profil nach dem "Tauchvorgang" eingelesen und zur weiteren Verarbeitung bereitgestellt.
Datenspeicherung und Archivierung
...
*Rohdaten an Bord:*
Eine zentrale Speicherung ist nicht vorgesehen. Es obliegt dem Anwender die Wasserschallprofile für eine weitere Verwendung z.B. mit den Daten des Hydrosweeps abzuspeichern.
