RV Investigator BGC-Argo Float Data for Southern Hemisphere Ocean Properties

High-resolution ocean measurements from Biogeochemical Argo floats deployed during RV Investigator voyages. The Australian Ocean Data Network provides these observations, which include temperature, salinity, dissolved oxygen, pH, nitrate, chlorophyll fluorescence, and backscatter. These datasets support investigations into the biological carbon pump, ocean acidification, and deoxygenation, and serve as in situ validation for satellite products.

Use Cases

• Modeling the ocean's biological carbon pump based on chlorophyll fluorescence and particulate backscatter data.
• Investigating long-term trends in ocean acidification based on pH measurements.
• Studying ocean deoxygenation based on dissolved oxygen time series.
• Validating satellite-based biogeochemical products using in situ measurements of key variables.
• Assessing spatial and temporal variability in Southern Hemisphere biogeochemistry based on float profiles.

Strengths

• Data includes high-resolution measurements of multiple biogeochemical properties.
• Contributes to sustained ocean observing efforts, particularly in the Southern Hemisphere.
• Supports validation of satellite-based ocean color products.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to RV Investigator voyage tracks.
