Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 6-12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Temperature and salinity were calibrated against CTD data from 7 m depth. For details to all processing steps see Data Processing Report.

Temperature was calibrated independently for both MCs against CTD data from 7 m depth. Value added to temperature data MC1 = -0.002058. Value added to temperature data MC2 = 0.000370.Salinity was calibrated independently for both MCs against CTD data from 7 m depth (tim is the time in days since Expocode of this cruise (06M220240607), i.e. since 2024-06-07T00:00:00): Value added to salinity data MC1 = -0.0002661tim+0.05212. Value added to salinity data MC2 = -0.0010718tim+0.00168.The salinity samples taken directly from the water inlet and attached to this dataset were not used for calibration.
