This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V01, titled: 'HEOBI: Heard Earth-Ocean-Biosphere Interactions' which departed Fremantle on the 8th January 2016 and returned to Hobart on the 27th February 2016. Data for 55 deployments were acquired using the Seabird SBE911 CTD unit 20, 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. 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 0.0013449 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the secondary oxygen and primary temperature and conductivity sensors. The dissolved oxygen data calibration fit had a S.D. of 0.91455uM. The agreement between the CTD and bottle data was good. A dual channel Fluorometer and an oxidation-reduction potential (ORP) 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. NOTE: The netCDF variable in the binned file has the incorrect instrument data for the fluorometer. In the published data it is as follows: fluorometer:manufacturer = "Chelsea" ; fluorometer:model = "Aquatracka" ; fluorometer:serialNo = "065941001" ; fluorometer:unitNo = 2. ; The data should read: fluorometer:manufacturer = "Wetlabs" ; fluorometer:model = " FLBBRTD" ; fluorometer:serialNo = "3698" ; fluorometer:unitNo = 2. ; The actual data is unaffected.
