This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2019_T01, titled: "Collaborative Australian Postgraduate Sea Training Alliance (CAPSTAN)". The voyage took place from Hobart (TAS) to Freemantle (WA) between April 29 and May 9, 2019.

Data for 5 deployments were acquired using the Sea-Bird SBE911 CTD 23, fitted with 36 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 secondary sensor had a standard deviation (SD) of 0.0021299 PSU, outside our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the secondary sensors.

The dissolved oxygen data calibration fit had a SD of 0.87858 µM. The agreement between the CTD and bottle data was good.

Biospherical PAR, Tritech Altimeter (100m), Transmissometer, ECO-Chlorophyll and ECO-Scattering sensors were also installed on the auxiliary A/D channels of the CTD.
