RV Investigator BGC-Argo: Southern Ocean Biogeochemical Profiles

RV Investigator voyages BGC Argo Float Data comprises high-resolution observations from Biogeochemical Argo profiling floats deployed during research voyages. The data includes measurements of temperature, salinity, dissolved oxygen, pH, nitrate, chlorophyll fluorescence, particulate backscatter, and solar radiation. These datasets support investigations into the ocean's biological carbon pump, anthropogenic CO₂ uptake, and long-term trends in deoxygenation and acidification.

Use Cases

• Validating satellite-based biogeochemical and ocean color products based on in situ measurements of chlorophyll fluorescence and backscatter.
• Investigating variability in the ocean's biological carbon pump based on profiles of dissolved oxygen, nitrate, and particulate matter.
• Analyzing long-term trends in ocean deoxygenation and acidification based on time-series measurements of dissolved oxygen and pH.
• Assessing spatial and temporal coverage of key biogeochemical variables in the Southern Hemisphere based on float deployment locations and profiles.

Strengths

• Provides high-resolution measurements of multiple physical and biogeochemical ocean properties.
• Contributes to sustained ocean observing efforts, particularly improving coverage in the Southern Hemisphere.
• Data is hosted by the authoritative Australian Ocean Data Network organization.

Limitations

• Critical metadata such as row count, specific column names, data license, and author are not provided in the available sources.
• The dataset's temporal and spatial coverage is not explicitly defined, limiting understanding of its scope.
• Multiple platform entries show conflicting 'last updated' dates (2026-06-27, 2026-06-04, 2026-04-04), indicating potential metadata inconsistency.
