Raw data acquired by two SBE21 thermosalinograph and two auxiliary SBE38 temperature sensor (Sea-Bird Scientific, USA) installed in an underway seawater flow-through system on board RV Polarstern were processed to yield a calibrated and validated data set of temperature and salinity along the cruise track. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) at a resolution of 1 sec, and converted to temperature and conductivity using the pre-deployment factory calibration coefficients. The converted data were averaged to 1 min values, outliers were removed, and sensor drift was corrected using coefficients obtained from a post-season calibration performed at Sea-Bird at the end of the measurement season. Salinity was calculated from internal temperature, conductivity and pressure according to the PSS-78 Practical Salinity Scale. Processed data are provided as 1 min means of seawater temperature, conductivity and salinity, aligned with position data taken from the master track. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010). More details are described in the attached processing report.
Raw data acquired by a thermosalinograph (SBE21, Sea-Bird GmbH) in combination with an external temperature sensor (SBE38, Sea-Bird GmbH) aboard RV Heincke were processed to generate a calibrated, quality-controlled dataset of seawater temperature and salinity. The raw sensor data were initially retrieved from the DSHIP database (https://dship.awi.de) at a temporal resolution of 1 second and converted into temperature and conductivity using the pre-deployment calibration coefficients. The thermosalinograph system aboard RV Heincke is typically replaced after each expedition season, with a recalibration conducted at the manufacturer's facilities after each exchange. After post-cruise recalibration of the instruments, additional correction factors were calculated and applied to account for sensor drift. Salinity was calculated from internally measured temperatures and conductivities following the Practical Salinity Scale (PSS-78). The processed dataset is provided as 1-minute averages of salinity and seawater external temperature, synchronized with the positional data from the expedition's master track. Quality flags were assigned in accordance with the SeaDataNet Data Quality Control Procedures (May 2010).
