South Atlantic Ocean Carbon and Hydrography Measurements from the BEAGLE2003 Cruise

South Atlantic Ocean chemical and physical data collected from the MIRAI research vessel between November 6 and December 5, 2003. The dataset includes dissolved inorganic carbon, alkalinity, pH, chlorofluorocarbons, isotopes, and nutrients, gathered using instruments like CTDs and titrators. Data were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the CLIVAR_A10_2003 program.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing ocean circulation and water mass age using chlorofluorocarbon (CFC-11, CFC-12, CFC 113) and tritium data.
• Studying nutrient dynamics and biological productivity based on nitrate, nitrite, phosphate, and silicate concentrations.
• Investigating changes in ocean chemistry and acidification trends based on pH and total alkalinity profiles.

Strengths

• Includes multiple key carbon system variables (DIC, TA, pH) for acidification studies.
• Contains time-series and profile data from a specific, well-documented research cruise (BEAGLE2003).
• Measures a suite of complementary tracers including CFCs and isotopes for water mass analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is from a single one-month cruise in 2003, limiting temporal and spatial generalizability.
