Thermosalinograph Keel 1 and Keel 2 data stored in data acquisition system DShip are uncorrected measurement data. |
The thermosalinograph is an instrument used to accurately determine sea surface conductivity and temperature. The remote temperature sensor SBE38 is integrated with the SBE21 Thermosalinograph. |
|
|
Both thermosalinographs keel 1 and keel 2 consist of SBE21, external thermometer SBE38, NMEA interface box and a pipe system with a flow meter. The system is located in the box keel. The water inflow is in about 11 m depending on the ships draft. |

Shortly after the cruise the uncorrected thermosalinograph measurement data are available at the DShip onshore system https://dship.awi.de/. As soon as a post-cruise calibration was performed, the data are processed and uploaded in [PANGAEA|http://www.pangaea.de/search?l&q=polarstern+thermosalinograph]. |
