The voyage took place between July 14 to July 29, 2022 departing from Brisbane (QLD) and returning to Brisbane. Data for 22 CTD deployments were acquired using the Sea-Bird SBE911 CTD 24, fitted with 36 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. Issues with the primary and secondary conductivity sensors were observed in the first 3 casts of the CTD deployment. To resolve these issues, the primary and secondary conductivity sensors were replaced. Subsequently, casts 4-22 were treated as a different deployment group. Casts 5 and 6 were diagnostic casts. The final conductivity calibration was based on a two-deployment groupings. The final calibration from the primary sensor had a standard deviation (SD) of 0.0011575 PSU, and 0.001534 PSU respectively, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a SD of 0.76684μM. The agreement between the CTD and bottle data was good. An Altimeter, PAR, Transmissometer, Fluorometer, and Turbidity sensor were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
