RV Investigator voyages BGC Argo Float Data

These datasets comprise observations from Biogeochemical Argo (BGC-Argo) profiling floats deployed during RV Investigator voyages. The floats collect high-resolution measurements of ocean physical and biogeochemical properties, including temperature, salinity, and combinations of dissolved oxygen, pH, dissolved nitrate, chlorophyll fluorescence, particulate backscatter, and incoming solar radiation.

The datasets support investigations into variability in the ocean’s biological carbon pump, the uptake of anthropogenic CO₂ by the ocean, and long-term trends in ocean deoxygenation and acidification. They are also relevant for marine resource management and provide essential in situ data for the validation of satellite-based biogeochemical and ocean colour products. The RV Investigator BGC-Argo datasets contribute to sustained ocean observing efforts, particularly in the Southern Hemisphere, by improving spatial and temporal coverage of key biogeochemical variables.
