The South Atlantic Ocean is the geographic scope for discrete sample and profile data collected aboard the POLARSTERN research vessel from 2012-01-07 to 2012-03-11. Data include dissolved inorganic carbon, alkalinity, temperature, salinity, dissolved oxygen, and nutrients like nitrate and phosphate. Mario Hoppema of the Alfred Wegener Institute and Toste Tanhua of GEOMAR collected this data as part of the CLIVAR_A12_06AQ20120107 cruise.
Use Cases
- Modeling ocean carbon storage and transport based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing water mass properties and circulation based on salinity, temperature, and hydrostatic pressure profiles.
- Studying nutrient cycling and primary production based on nitrate, nitrite, phosphate, and silicate concentrations.
- Investigating ocean ventilation and tracer distribution based on Chlorofluorocarbon-12 (CFC-12) and Sulfur Hexafluoride (SF6) data.
Strengths
- Data collection covers a specific two-month cruise (2012-01-07 to 2012-03-11) in the South Atlantic Ocean.
- Includes multiple co-located chemical and physical parameters such as DIC, alkalinity, oxygen, nutrients, and temperature.
- Data were collected by named principal investigators from recognized research institutions (Alfred Wegener Institute, GEOMAR).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
- Data may reflect temporal and geographic bias inherent to a single research cruise in early 2012.
