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

Observations from Biogeochemical Argo profiling floats deployed during RV Investigator voyages. The floats collect high-resolution measurements of ocean physical and biogeochemical properties. The datasets are contributed by the Australian Ocean Data Network and were last updated on 2026-04-28.

Use Cases

• Investigating variability in the ocean's biological carbon pump based on biogeochemical property measurements
• Analyzing ocean uptake of anthropogenic CO₂ based on pH and dissolved oxygen data
• Studying long-term trends in ocean deoxygenation and acidification based on time-series observations
• Validating satellite-based biogeochemical and ocean colour products using in-situ float data
• Informing marine resource management decisions based on Southern Hemisphere ocean state

Strengths

• Includes high-resolution measurements of multiple biogeochemical variables as described
• Contributes to sustained ocean observing efforts, particularly improving coverage in the Southern Hemisphere
• Supports investigations into multiple key climate and oceanographic processes

Limitations

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