Shortly after the cruise the uncorrected thermosalinograph measurement data are available at the DShip onshore system https://dms.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]. |
