Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. Temperature and salinity were calibrated against CTD data from 5 m depth. For details to all processing steps see Data Processing Report.

Temperature was calibrated independently for both TSGs against CTD data from 5 m depth. Value added to temperature data TSG1 = -0.002310. Value added to temperature data TSG2 = -0.003363.Salinity was calibrated independently for both TSGs against CTD data from 5 m depth (tim is the time in days since Expocode of this cruise (06M320240810), i.e. since 2024-08-10T00:00:00): Value added to salinity data TSG1 = 0.0001948tim-0.013527.
