This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2017_T02 titled: "Collaborative Australian Postgraduate Sea Training Alliance Network Pilot Voyage 1." The voyage took place from Henderson (WA) to Hobart (TAS) between November 14 and November 26, 2017.
Data for 13 deployments were acquired using the Seabird SBE911 CTD unit 23 fitted with 24 twelve litre bottles on the rosette sampler. Samples were collected on casts 1-5 and casts 7-10. Sea-Bird-supplied and CSIRO calibration factors were used to compute the pressures, preliminary conductivity oxygen and temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.
The final conductivity calibration was based on one deployment grouping. The primary sensor had a standard deviation of 0.0009. The secondary sensor had a standard deviation of 0.001. Both sensors had a standard deviation (S.D) less than our target of ‘better than 0.002 PSU’.
The final oxygen calibration from the primary sensor had a standard deviation of 0.9966uM. The final oxygen calibration for the secondary sensor had a standard deviation of 1.0125uM. The agreement between the sensor and bottle data was good for both sensors. Both Oxygen sensors calibrated closely.
Both the primary and secondary sensor output has been included in the final data product for temperature, salinity and oxygen.
A Biospherical photosynthetically active radiation (PAR), Wetlabs transmissometer and Chelsea fluorometer sensors were also installed on the auxiliary A/D channels of the CTD.
The collected data has been 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.
