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 the CSIRO NCMI Information and Data Centre. Credit CTD data processed by Kendall Sherrin, Ian Hawkes (CSIRO NCMI). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2021_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between April 14 and April 28, 2021 departing from Hobart (TAS) and arriving in Hobart. Data for 6 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. 0015434PSU, 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 0.90687 μM. The agreement between the CTD and bottle data was good. Transmissometer, Wetlabs FLBBRTD and Altimeter were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO National Collections and Marine Infrastructure (NCMI) 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.
