The voyage took place from Hobart (TAS) to Hobart between January 10 and February 21, 2018. Data for 108 deployments were acquired using the Seabird SBE911 CTD 24, fitted with 36 twelve litre bottles on the rosette sampler. Seabird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. Seabird/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 for deployments 14-108 had a standard deviation (SD) of 0.0012686 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 dbar binned averaged netCDF files were produced using data from the primary sensors. The dissolved oxygen data calibration fit for deployments 14-108 had a SD of 0.78897 µM and 0.78113 µM for the primary and secondary sensors respectively. The agreement between the CTD and bottle data was good. Altimeters (200m and 500m), Transmissometer, PAR, ECO Chlorophyll and ECO OBS (Optical Back-Scatter) sensors 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.Progress Code: completedMaintenance and Update Frequency: asNeededStatement: Original field data.

Brief description

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V01 titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place from Hobart (TAS) to Hobart between January 10 and February 21, 2018.

Data for 108 deployments were acquired using the Seabird SBE911 CTD 24, fitted with 36 twelve litre bottles on the rosette sampler. Seabird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. Seabird/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 for deployments 14-108 had a standard deviation (SD) of 0.0012686 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 dbar binned averaged netCDF files were produced using data from the primary sensors.

The dissolved oxygen data calibration fit for deployments 14-108 had a SD of 0.78897 µM and 0.78113 µM for the primary and secondary sensors respectively. The agreement between the CTD and bottle data was good.
Altimeters (200m and 500m), Transmissometer, PAR, ECO Chlorophyll and ECO OBS (Optical Back-Scatter) sensors 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.
