This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V07, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies south west Tasmania; The voyage took place from Hobart (TAS) to Hobart between August 20 and August 24, 2018. Data for 1 deployment was acquired using the Seabird SBE911 CTD unit 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 (S.D) of 0.0011658 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary conductivity and secondary oxygen sensors. The dissolved oxygen data calibration fit had a S.D. of 0.33778 uM. The agreement between the CTD and bottle data was good. A Biospherical photosynthetically active radiation (PAR) meter, Seapoint Turbidity Meter (Nephelometer) and a Chelsea Fluorometer 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 (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.
