One CTD was mounted on a stainless-steel rosette and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, oxygen (SBE43), PAR (Biospherical Licor Chelsea sensor), fluorometer (Wet Labs ECO-AFL/FL), turbidity (Wet Labs ECO-NTU) and an altimeter. The second CTD was mounted on a titanium rosette used for trace metal clean collection of water samples, and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, two oxygen sensors (SBE43), transmissometer (Wet Labs C-Star), turbidity (OBS Seapoint) and an altimeter. The oxygen and salinity data were calibrated against discrete water samples.171.999-71.72899999999998-33.608-25.718South Pacific OceanBundesministerium für Bildung und Forschung, Bonnhttps://doi.org/10.13039/50110000234703GPF 18-1_032GEOTRACES GP21
