The South Atlantic and Southern Oceans (>60°S) are the focus of this dataset containing chemical and physical oceanographic measurements. It includes data on dissolved inorganic carbon, carbon dioxide partial pressure, chlorofluorocarbons, nutrients, and isotopes collected via CTD and bottle sampling aboard the POLARSTERN from June to December 1986. The data were collected by researchers from Columbia University and Gothenburg University as part of the ANT_V2_1986 cruise.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and carbon dioxide fugacity measurements.
- Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) and tritium data.
- Analyzing nutrient cycling in polar oceans based on nitrate, phosphate, and silicate concentrations.
- Calibrating and validating global ocean biogeochemical models using the suite of co-located chemical and physical parameters.
Strengths
- Data covers a specific, historically significant research cruise (ANT V/2_1986) in a critical polar region.
- Includes a multi-parameter suite of 18+ chemical and physical variables measured concurrently.
- Associated with the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program, suggesting a standardized collection framework.
Limitations
- Last updated 1986-12-14 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
