Abstract:
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 calculated within the interior TSG from conductivity and interior temperature. Temperature and salinity were validated against CTD data from 5 m depth. Finally, TSG1 was chosen for publication. For details to all processing steps see Data Processing Report.

Comment:
Temperature was calibrated independently for both TSGs against CTD data from 5 m depth. Value added to temperature data TSG1 = -0.001234. Value added to temperature data TSG2 = -0.004627.
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 (06M320250730), i.e. since 2025-07-30T00:00:00): Value added to salinity data TSG1 = -0.000201*tim-0.00840. Value added to salinity data TSG2 = 0.000031*tim+0.02713.
TSG1 was chosen for publication.
