CLIVAR A21 JC031 2009: Ocean Carbon and Hydrography Profiles from the Southern Oceans

CLIVAR_A21_JC031_2009 is a dataset of discrete sample and profile observations collected from the RRS JAMES COOK research vessel. The data includes dissolved inorganic carbon, alkalinity, temperature, salinity, oxygen, and nutrients from the South Atlantic, South Pacific, and Southern Oceans. Dorothee C. E. Bakker of the University of East Anglia collected these measurements during a cruise from February 3 to March 3, 2009.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing water mass properties and circulation based on temperature, salinity, and hydrostatic pressure profiles.
• Studying nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate data.
• Assessing ocean acidification trends based on paired total alkalinity and dissolved inorganic carbon observations.

Strengths

• Data includes multiple key ocean carbon and hydrographic variables measured together.
• Observations are from a specific, documented research cruise (CLIVAR_A21_JC031_2009) with a known time range.
• Measurements cover a broad geographic region across three major ocean basins.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
