RV Investigator IN2025_V06 CTD Data from the Coral Sea Marine Park

The Coral Sea Marine Park voyage IN2025_V06 collected conductivity, temperature, and depth (CTD) data between October 10 and November 14, 2025. Data for 41 CTD deployments were processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. The dataset includes auxiliary sensor readings for dissolved oxygen, fluorescence, chlorophyll, and turbidity.

Use Cases

• Analyze vertical water column profiles based on conductivity, temperature, and depth (CTD) data.
• Study deep-sea biodiversity correlations based on auxiliary sensor data for fluorescence, chlorophyll, and turbidity.
• Assess water mass properties based on calibrated dissolved oxygen measurements.
• Model oceanographic processes in the Coral Sea Marine Park based on time-series data from a specific voyage.

Strengths

• Data from 41 CTD deployments provides multiple sampling points.
• Calibration metrics are provided, with a final conductivity calibration standard deviation of 0.0025203 PSU.
• Automated quality control was applied to remove spikes and out-of-range values.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The final conductivity calibration marginally missed the target precision of 'better than 0.002 PSU'.
