RV Investigator BGC-Argo Float Data: Southern Ocean Biogeochemistry

Southern Hemisphere ocean data from Biogeochemical Argo profiling floats deployed during RV Investigator voyages. The floats collect high-resolution measurements of physical and biogeochemical properties, including temperature, salinity, dissolved oxygen, pH, nitrate, chlorophyll fluorescence, particulate backscatter, and incoming solar radiation. These datasets support research into the biological carbon pump, ocean acidification, deoxygenation trends, and provide in situ validation for satellite ocean color products.

Use Cases

• Investigating variability in the ocean's biological carbon pump based on chlorophyll fluorescence and particulate backscatter measurements.
• Assessing long-term trends in ocean acidification and deoxygenation using pH and dissolved oxygen time series.
• Validating satellite-based biogeochemical and ocean colour products with in situ data.
• Supporting marine resource management with sustained observations of key biogeochemical variables.

Strengths

• Data contributes to sustained ocean observing efforts, improving spatial and temporal coverage in the Southern Hemisphere.
• Collects high-resolution measurements of multiple key biogeochemical variables simultaneously.

Limitations

• Column names, row counts, file sizes, and license information are not provided in any source.
• Metadata completeness is low, with no details on specific voyages, float IDs, or temporal coverage.
