WOCE_A08 cruise data includes discrete measurements of carbon dioxide partial pressure, dissolved inorganic carbon, and chlorofluorocarbons collected aboard the METEOR research vessel. The data were collected by researchers from Universitat Kiel and Kenneth Johnson as part of the World Ocean Circulation Experiment between March and May 1994. The final WOCE collection covers approximately 23,000 stations from 94 cruises conducted between 1990 and 1998.
Use Cases
- Modeling ocean carbon sequestration based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
- Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) and tritium tracer data.
- Calibrating biogeochemical models with concurrent measurements of nutrients, salinity, and potential temperature.
- Studying historical ocean conditions and anthropogenic impact during the 1990s WOCE survey period.
Strengths
- Data collection is part of the major World Ocean Circulation Experiment (WOCE), a benchmark for climate research.
- Includes multiple chemical tracers (CFCs, tritium, helium-3) alongside core carbon system variables.
- Covers a specific, well-documented research cruise (WOCE_A08) with a clear temporal (1994-03-29 to 1994-05-11) and spatial (South Atlantic Ocean) scope.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1994-05-11; freshness should be verified for contemporary climate studies.
- Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
