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 estimated within the interior TSG from conductivity and interior temperature.

Comment:

Salinity was calibrated independently for both TSGs (tim is the time in days since Expocode of this cruise (06M320211222), i.e. since 2021-12-22T00:00:00): Value added to salinity data TSG1 = 0.0002556*tim+0.01025. Value added to salinity data TSG2 = 0.0001221*tim+0.00558. No correction against independent data was performed for temperature. Finally, TSG1 was chosen for publication. For details to all processing steps see Data Processing Report.
