This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2019_V01, titled: "The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean." The voyage took place from Hobart (TAS) to Hobart between January 19 and March 5, 2019. Data for 28 deployments were acquired using the Sea-Bird SBE911 CTD 23, fitted with 24 twelve litre bottles on the rosette sampler. CSIRO-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 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 (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.
