RV Investigator Voyage IN2025_V06 CTD Data from the Coral Sea Marine Park

41 CTD deployments collected by the RV Investigator during voyage IN2025_V06 from October 10 to November 14, 2025. Data includes pressure, conductivity, temperature, dissolved oxygen, PAR, fluorescence, chlorophyll, and turbidity measurements. The processed data were quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyzing deep-sea biodiversity patterns based on environmental sensor data.
• Studying water column properties like temperature and salinity gradients.
• Modeling dissolved oxygen distribution in the Coral Sea Marine Park.
• Investigating chlorophyll fluorescence and turbidity for biological productivity assessments.
• Calibrating sensor data against bottle samples for quality assurance.

Strengths

• 41 discrete CTD deployments provide multiple sampling points.
• Data underwent automated QC to remove spikes and out-of-range values.
• Calibration metrics are provided, including a conductivity SD of 0.0025203 PSU and dissolved oxygen SD of 0.88132 μM.
• Multiple auxiliary sensors (PAR, altimeter, fluorescence, transmissometer, chlorophyll, turbidity) were installed.

Limitations

• The final conductivity calibration standard deviation marginally exceeded the target of 0.002 PSU.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
