This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V02 Titled: "SOTS: Southern Ocean Time Series Automated Moorings for Climate and Carbon Cycle Studies Southwest of Tasmania". The voyage took place between the 13th March to 16th of April, 2016 departing Hobart (TAS) and returning to Hobart (TAS). Data for 40 deployments were acquired using the Seabird SBE911 CTD 20, fitted with 24 ten litre bottles on the rosette sampler. Sea-Bird-supplied and O&A Calibration Facility calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO 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 secondary sensor had a standard deviation (S.D) of 0.00138 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration from the secondary sensor was used for the final calibration. The fit had a S.D. of 0.792 uM. The agreement between the CTD and bottle data was good. The Biospherical photosynthetically active radiation (PAR), C-Star transmissometer and the Wetlabs ECO chlorophyll and scattering sensors were also installed on the auxiliary A/D channels of the CTD. The lowered ADCP was also attached to the package, logging internally during each cast. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) 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.
