This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V05, titled: "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." The voyage took place between September 28 and October 24, 2016 departing from Brisbane (QLD) and arriving in Brisbane. Data for 62 deployments were acquired using the Seabird SBE911 CTD 21 and CTD 20, fitted with 24 twelve-litre bottles on the rosette sampler. Seabird-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. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0014061 PSU, well within our target of ‘better than 0.002 PSU.’ The standard product of 1 dBar-binned averages were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a SD of 0.67142 µM. The agreement between the CTD and bottle data was good. Altimeter, Photosynthetically Active Radiation (PAR) sensor, Colored Dissolved Organic Matter (CDOM) sensor, Fluorometer, Transmissometer, Nephelometer, and Nitrate sensor 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.
