CARIOCA Buoy 1997: Surface Ocean Carbon Dioxide Measurements in the Atlantic

NCEI Accession 0157739 contains surface underway observations of carbon dioxide partial pressure and other variables collected in the North and South Atlantic Ocean from June to September 1997. The data were collected by researchers from Universite Pierre et Marie Curie and the University of East Anglia using carbon dioxide gas analyzers and equilibrators. These measurements are part of the CARIOCA Buoy 1997 fCO2 Data set.

Use Cases

• Modeling air-sea carbon dioxide flux based on partial pressure measurements.
• Analyzing temporal trends in surface ocean carbon chemistry during the 1997 observation period.
• Validating satellite-derived sea surface temperature products with in-situ measurements.
• Studying correlations between fluorescence, barometric pressure, and carbon dioxide levels in the ocean surface layer.

Strengths

• Data collection spans a three-month period from 1997-06-19 to 1997-09-16.
• Includes multiple concurrent variables: carbon dioxide partial pressure, sea surface temperature, fluorescence, and barometric pressure.
• Data originates from a recognized scientific cruise (CARIOCA_1997) and is hosted by NOAA NCEI.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1997-09-16; freshness should be verified for contemporary climate studies.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
