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 Francis Chui (CSIRO O&A). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2020_V09 titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania". The voyage took place between 25 August and 12 September, 2020 departing from Hobart (TAS) and arriving in Hobart (TAS). Data for 6 deployments were acquired using the Sea-Bird SBE911 CTD 25, fitted with 24 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 0.0008174 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 0.89571 μM. The agreement between the CTD and bottle data was good. Transmissometer, Wetlabs Eco-FLBB and Altimeter were also installed on the auxiliary A/D channels of the CTD. It should be noted that the transmissometer signal below 700 decibar should be treated as suspect. 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 ...
