Abstract:
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 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. No correction against independent data was performed for temperature. Salinity was calibrated against independent water samples. For details to all processing steps see Data Processing Report.

Comment:
Salinity was calibrated independently against water samples from 6.5 m depth (tim is the time in days since Expocode of this cruise (06M220230923), i.e. since 2023-09-23T00:00:00). Value added to salinity data MC1 = -0.0002523*tim-0.00270. Value added to salinity data MC2 = -0.0030801*tim+0.02307.
