RV Investigator Voyage IN2026_V05 CTD Data

This record describes the CTD data collected on Investigator voyage IN2026_V05, titled: "Next Generation of Ocean LiDAR." The voyage took place between August 27, 2026 and September 07, 2026 (AEST), departing from Brisbane and returning to Brisbane.

Data for 20 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #22, 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.

On this voyage a minor change was required in the processing pipeline and CapPro software to support the processing of three transmissometers.

The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0023095 PSU, outside our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.

The dissolved oxygen data calibration fit had a SD of 0.7855 μM. The agreement between the CTD and bottle data was good. CDOM, Red/Green/Blue C-Star Transmissometers, ECO Fluorometer, ECO Backscatter and altimeter (as required for bottom approach) were also installed on the auxiliary A/D channels of the CTD.

The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.
