Biogeochemical Argo Float Data from RV Investigator Voyages

This dataset 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. The data supports investigations into the ocean's biological carbon pump, CO2 uptake, deoxygenation, and acidification.

Use Cases

• Analyze chlorophyll fluorescence and particulate backscatter data to model phytoplankton biomass and the biological carbon pump in the Southern Hemisphere.
• Investigate correlations between dissolved oxygen, pH, and temperature measurements to study ocean deoxygenation and acidification trends.
• Use dissolved nitrate and salinity profiles to understand nutrient cycling and its impact on marine biogeochemistry.
• Validate satellite-based ocean color products by comparing them with in situ chlorophyll fluorescence and incoming solar radiation measurements.

Strengths

• Data includes high-resolution measurements of multiple biogeochemical variables like dissolved oxygen, pH, and nitrate.
• Contributes to sustained ocean observing efforts, improving spatial and temporal coverage in the Southern Hemisphere.
• Supports validation of satellite-based biogeochemical products with essential in situ data.

Limitations

• The specific number of rows, columns, and total data volume is unknown.
• Data file formats include HTML and PNG, which may not be standard for direct numerical analysis and require extraction.
• Geographic coverage is focused on the Southern Hemisphere, potentially limiting global applicability.
