Description
RV Investigator voyages BGC Argo Float Data comprises observations from Biogeochemical Argo profiling floats deployed during RV Investigator voyages. The floats collect high-resolution measurements of ocean physical and biogeochemical properties, including temperature, salinity, dissolved oxygen, pH, nitrate, chlorophyll fluorescence, and backscatter. These datasets from the Australian Ocean Data Network support investigations into the ocean's biological carbon pump, anthropogenic CO₂ uptake, deoxygenation, and acidification.
Use Cases
Investigating variability in the ocean's biological carbon pump based on biogeochemical property measurements
Studying the uptake of anthropogenic CO₂ by the ocean based on pH and dissolved gas data
Analyzing long-term trends in ocean deoxygenation and acidification based on dissolved oxygen and pH time series
Validating satellite-based biogeochemical and ocean colour products based on in situ measurements
Informing marine resource management based on spatial and temporal coverage of key ocean variables
Strengths
Data includes high-resolution measurements of multiple ocean properties, including temperature, salinity, dissolved oxygen, pH, nitrate, chlorophyll fluorescence, and backscatter
Datasets contribute to sustained ocean observing efforts, particularly improving coverage in the Southern Hemisphere
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
Data may reflect geographic bias inherent to data_gov_au, focusing on RV Investigator voyage areas
