Discrete sample and profile data collected from the RRS JAMES COOK in the South Atlantic Ocean from March 7 to April 21, 2009. Brian A. King and Ute Schuster collected measurements of dissolved inorganic carbon, alkalinity, oxygen, nutrients, temperature, and salinity during cruise CLIVAR A9.5. The data support the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's mission to quantify changes in ocean heat, freshwater, and carbon dioxide.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions (nitrate, phosphate, silicate) in the South Atlantic Ocean.
- Studying changes in ocean heat and freshwater content based on temperature and salinity profiles.
- Quantifying dissolved oxygen levels for biogeochemical studies.
Strengths
- Data collected during a dedicated scientific cruise (CLIVAR A9.5/JC032) with a clear research mission.
- Includes multiple key oceanographic variables (DIC, alkalinity, oxygen, nutrients, temperature, salinity) for integrated analysis.
- Profile and discrete sample data provide both vertical and point measurements.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data covers a specific 45-day period in 2009; temporal scope is limited.
