RV Investigator Voyage IN2025_V06 CTD Data
This record describes the CTD data collected on Investigator voyage IN2025_V06, titled: "The Coral Sea frontier: Deep-sea biodiversity assessment of the Coral Sea Marine Park." The voyage took place between October 10, 2025 and November 14, 2025 (AEST), departing from Brisbane and returning to Brisbane.
Data for 41 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #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 0.0025203 PSU, marginally outside our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the primary sensors.
The dissolved oxygen data calibration fit had a SD of 0.88132 μM. The agreement between the CTD and bottle data was good.
PAR, altimeter, g\fluorescence, transmissometer, chlorophyll and turbidity sensors 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.

Deployment 3 - Communications were lost at the beginning of the upcast and the Deck box alarmed. Deployment was aborted. Bottle samples were collected at the bottom and the downcast was processed in CapPro. • Bottles 9 and 31 did not fire on casts 24, 30, 35 and 36 due to a fault with the CTD bottle release mechanism. Release Mechanism 1284 was replaced by Release Mechanism 0964 after cast 36 to address the issue. • CTD winch experienced spooling issues during several casts, notably 13, 16, 29 and 32, resulting in delayed upcast and retrieval for respooling. • No bottle samples were collected on cast 33 as the cast was for the purpose of respooling and winch spooling tests. As a result, CTD calibrations exclude cast 33. No further spooling issues were observed following this deployment. • Altimeter data was observed as noisy during early deployments, particularly in shallow water (less than ~200m). The sensor channel for the PAR and altimeter were swapped after cast 5. Minimal impacts on the PAR sensor and minor improvements to the quality of the altimeter data was observed following the change.
