This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_T01, titled: "Continuity of Australian terranes into Zealandia: towards a geological map of the east Gondwana margin". The voyage took place from Laukota (Fiji) to Hobart (TAS) between June 30 and July 14, 2016. Data for 13 deployments were acquired using the Seabird SBE911 CTD 20, fitted with 36 twelve litre bottles on the rosette sampler. CSIRO supplied calibrations were applied to the temperature, conductivity, oxygen, and pressure data. The data were subjected to automated QC to remove spikes and out-of-range values. During cast 1, a communications error occurred at a depth of 250m (alarm on the deck unit) and the CTD was recovered. All other casts proceeded without issue. The calibrations derived from bottle samples from subsequent casts were applied to cast 1. There were no changes to the sensor package for the duration of the voyage. The final calibration from the secondary sensor for casts 2-13 had a standard deviation (S.D) of 0.0012559 PSU, well within our target of ‘better than 0.002 PSU’. The final calibration from the secondary dissolved Oxygen sensor for casts 2-13 had a standard deviation (S.D) 0.65093 uM/l. The agreement between the CTD and bottle data was good. The standard product of 1 dbar binned averaged were produced using data from the secondary temperature and conductivity sensors, and the secondary Oxygen sensor. A Fluorometer, Transmissometer, and altimeter were also installed and logged 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.
