Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. Data processing and quality control by the Marine National Facility Data Acquisition and Processing Group (DAP). Data were processed using the new CapPro system. Data archived by CSIRO O&A - IDC. Credit CTD data processed by Steve Van Graas (CSIRO O&A). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V04, titled: "Constraining external iron inputs and cycling in the southern extension of the East Australian Current." The voyage took place from Hobart (TAS) to Hobart between September 11 and October 8, 2018. Data for 25 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. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0012361 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a SD of 0.7997µM. The agreement between the CTD and bottle data was good. A Wetlabs CSTAR Transmissometer, Chelsea Aquatracka III Fluorometer, Wetlabs CDOM Fluorometer, and PAR 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.
