This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2022_V06, titled: "Integrated Marine Observing System: Monitoring of East Australian Current property transports at 27 degrees South." 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). Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
