During Sonne cruise SO283 in the western South Atlantic (19 March - 25 May, 2021) conductivity, temperature, and depth (CTD) measurements were made out using a SeaBird 9+ instrument equipped with dual sensors for temperature, conductivity and oxygen, as well as Wetlabs fluorescence and turbidity sensors. Calibration for conductivity and oxygen was performed at sea using water samples. The CTD data were reprocessed with the corrections applied. After filtering the alignment of the different sensors in the TC-duct was corrected, the standard pressure and temperature correction was applied and loops are removed using the standard Seabird algorithms. Downcast data were separated and averaged over 0.5 dB intervals.
