This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V03 titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27S." The voyage took place between April 19 and May 10, 2018 departing Brisbane (QLD) and returning to Brisbane. Data for 14 deployments were acquired using the Seabird SBE911 CTD unit 24 fitted with 24 twelve litre bottles on the 32 bottle rosette sampler. Samples were collected on all casts. Sea-Bird-supplied and CSIRO calibration factors were used to compute the pressures, preliminary conductivity oxygen and temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. The final conductivity calibration for each deployment was calculated using the sensors with the lowest residuals when compared with the values measured by the hydrochemistry team. The final calibration from chosen sensors all had a standard deviation (SD) less than our target of ‘better than 0.002 PSU’. The dissolved oxygen data calibration generally showed a good agreement between the CTD and bottle data. Biospherical photosynthetically active radiation (PAR), Wetlabs transmissometer and Chelsea fluorometer sensors were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
