Abstract:
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). Usually, the SMBs are changed after ~12 hours. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the SMB from conductivity and interior temperature. Temperature and salinity were calibrated against CTD data from 4 m depth. For details to all processing steps see Data Processing Report.

Comment:
Temperature was calibrated independently for both SMBs against CTD data from 4 m depth. Value added to temperature data SMB_A = 0.002785. Value added to temperature data SMB_B = 0.003348.
Salinity was calibrated independently for both SMBs against CTD data from 4 m depth (tim is the time in days since Expocode of this cruise (06SN20230414), i.e. since 2023-04-14T00:00:00): Value added to salinity data SMB_A = -0.0004372*tim-0.02633. Value added to salinity data SMB_B = -0.0001734*tim+0.01095.
