Both systems worked throughout the cruise. While temperature is taken at the water inlet in about 4 m depth, salinity is calculated within the interior TSG from conductivity and interior temperature. No temperature validation was performed. Salinity was validated with independent water samples taken at the water inlet. For details to all processing steps see Data Processing Report.Salinity was validated independently with water samples from 4m depth (tim is the time in days since Expocode of this cruise (06AK20260509), i.e. since 2026-05-09T00:00:00): Value added to salinity data = -0.0014332*tim+0.04485.10.015515516.518584454.140691355.8114968
