RV Investigator Voyage IN2024_V03: CTD Data from Southeast Marine Ecosystem Survey

CSIRO National Collections and Marine Infrastructure collected 83 CTD deployments during the RV Investigator voyage IN2024_V03 in May 2024. Data includes pressure, conductivity, temperature, dissolved oxygen, and auxiliary sensor readings from the southeast marine ecosystem. The processed data is archived by the CSIRO Information and Data Centre.

Use Cases

• Analyzing water column structure based on pressure, temperature, and salinity (conductivity) profiles.
• Studying dissolved oxygen dynamics and their relation to marine ecosystem health.
• Investigating biogeochemical properties using auxiliary sensor data for chlorophyll-a, CDOM, and scattering.
• Assessing data quality and sensor performance by comparing primary and secondary sensor values mentioned in the description.

Strengths

• Data from 83 CTD deployments provides multiple sampling points.
• Final conductivity calibration had a standard deviation of 0.0018351 PSU, meeting a target of 'better than 0.002 PSU'.
• Automated quality control was applied to remove spikes and out-of-range values.
• Multiple auxiliary sensors (altimeter, PAR, CDOM, Chlorophyll-a, Scattering) were installed, suggesting a multi-parameter dataset.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
