Quack Birgit bquack@geomar.de Krahmann Gerd gkrahmann@geomar.de 2021 Physical oceanography (CTD) during SONNE cruise SO234/2 dataset https://doi.org/10.1594/PANGAEA.929007 2021-03-11T14:53:44 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.
