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 on 12/04/2018. Credit CTD data processed by Karl Malakoff (CSIRO O&A). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies south west Tasmania; Subantarctic Biogeochemistry of Carbon and Iron." The voyage took place between March 3 and March 21, 2018 departing from Hobart (TAS) and arriving in Hobart. Data for 7 deployments were acquired using the Seabird SBE911 CTD unit 24, fitted with 36 twelve litre bottles on the rosette sampler. Samples were collected on casts 2-6. 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 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 (S.D) less than our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary conductivity and temperature sensors and the secondary oxygen sensor. The dissolved oxygen data calibration generally showed a good agreement between the CTD and bottle data. A Biospherical photosynthetically active radiation (PAR), Wetlabs transmissometer, Chelsea fluorometer and the Wetlabs ECO chlorophyll and Eco-scattering sensors were also installed on the auxiliary A/D channels of the CTD.
