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

CTD (Conductivity, Temperature, Depth) data from 41 deployments during a research voyage in the Coral Sea Marine Park between October and November 2025. The data were collected using a Sea-Bird SBE911 CTD unit and processed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. Measurements include dissolved oxygen, fluorescence, chlorophyll, turbidity, PAR, and transmissometer readings from auxiliary sensors.

Use Cases

• Modeling water column structure based on conductivity, temperature, and depth profiles.
• Assessing deep-sea biodiversity by correlating biological sensor data (fluorescence, chlorophyll) with physical parameters.
• Calibrating oceanographic models using the quality-controlled, 1-decibar binned average data product.
• Studying dissolved oxygen dynamics in the Coral Sea Marine Park based on the calibrated sensor data.

Strengths

• Data from 41 separate CTD deployments provides multiple sampling points.
• Quality control was applied to remove spikes and out-of-range values.
• Final conductivity calibration had a reported standard deviation of 0.0025203 PSU.
• Dissolved oxygen calibration fit had a standard deviation of 0.88132 μM.

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 standard deviation was marginally outside the target of 'better than 0.002 PSU'.
