Seabird 911plus systems equipped with dual temperature-conductivity-oxygen sensors were employed. The systems had a 24-bottle water sampling rosette with 10 l Niskin bottles. Water sampling, processing, and calibration followed GO-SHIP recommendations (Swift, 2010; McTaggart et al., 2010; Uchida et al., 2010) and included the recommended steps Data Conversion, Sensor Time-Alignment, Creation of Bottle Files, Outlier Removal, Pressure Sensor Filtering, Conductivity Cell Thermal Mass Correction, Ship Roll Correction and Deck Offset Correction by Loop Editing, as well as Derivation of Calculated Properties. After these steps, conductivity and oxygen readings were calibrated against values determined with salinometry (see section 4.1.4) and Winkler titration (see section 4.2.1), respectively. Finally, the downcast data was averaged over 1 dbar wide intervals. An independent upcast calibration was used to obtain calibrated CTDO values coincident with the discrete water samples. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.929007"! ** PO-GLOBAL-SVN = 684 used on 30-Apr-2020 18:25:17 Matlab = 9.4.0.813654 (R2018a) Release = 2 nc_uncertainty_p = 2.000000 nc_uncertainty_t = 0.002000 nc_uncertainty_s = 0.010000 nc_uncertainty_o = 1.500000 nc_comment = Salinity data is derived from manufacturer calibration. Checks against climatological data show no obvious problems. Oxygen has been calibrated for the combined data from cruise legs 234/2 and 235/1.
