This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2021_T01, titled: "Transit: Brisbane to Darwin". The voyage took place between June 9 to June 23 2021 departing Brisbane and arriving in Darwin.
Data for 12 deployments were acquired using the Sea-Bird SBE911 CTD #24, 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 primary sensor had a standard deviation (SD) of 0.0033235 PSU, outside our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the primary sensors.
The dissolved oxygen data calibration fit had a SD of 0.64275 μM. The agreement between the CTD and bottle data was good.
PAR, upward and downward facing Teledyne Lowered Acoustic Doppler Current Profilers (LADCP), Wetlabs C-Star Transmissometer, ECO Chlorophyl and Scattering, CDOM, and UBAT sensors were also installed on the auxiliary A/D channels of the CTD.
The collected data were subsequently processed and archived within the CSIRO National Collections and Marine Infrastructure (NCMI) 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.
