| Summary: | 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 processed and archived on 01/05/2018. Data were processed using the new CapPro system. The data for this voyage were acquired with the CSIRO CTD unit 24, a Seabird SBE911 with dual conductivity and temperature sensors. The CTD was additionally fitted with SBE43 dissolved oxygen sensors, altimeter, transmissometer, PAR, ECO fluorometer and ECO OBS sensors. Credit CTD data processed by Francis Chui (CSIRO O&A) Data archived by Vito Dirita (CSIRO O&A). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V01 titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place from Hobart (TAS) to Hobart between January 10 and February 21, 2018. Data for 108 deployments were acquired using the Seabird SBE911 CTD 24, fitted with 36 twelve litre bottles on the rosette sampler. Seabird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. Seabird/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 for deployments 14-108 had a standard deviation (SD) of 0.0012686 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 dbar binned averaged netCDF files were produced using data from the primary sensors. The dissolved oxygen data calibration fit for deployments 14-108 had a SD of 0.78897 µM and 0.78113 µM for the primary and secondary sensors respectively. The agreement between the CTD and bottle data was good. Altimeters (200m and 500m), ...
