Attention:

Thermosalinograph data stored in data acquisition system DShip are uncorrected measurement data.

Summary

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.

Components

The thermosalinograph consists of the SBE21, the external thermometer SBE38, the NMEA interface box and a pipe system with a flow meter. The system is located in the bow room of the tank deck. Two devices of type SBE21 and two devices of type SBE38 exist on RV Heincke. They are used in rotation and calibrated regularly.

Data archiving on land

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 is performed, the data are processed and the corrected data are uploaded in http://www.pangaea.de
