This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2019_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania; Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site." The voyage took place from Hobart (TAS) to Hobart between March 14 and April 4, 2019.
Data for 22 deployments were acquired using the Sea-Bird SBE911 CTD #23, 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. A Weblabs CSTAR Transmissometer, QCP PAR sensor and Wetlabs FLBBNTU chlorophyll and backscatter sensor was 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.
