Discrete sample and profile data from the R/V Marion Dufresne cruise WOCE_I06Sb in the Indian and Southern Oceans from 1996-02-20 to 1996-03-31. The data include dissolved inorganic carbon, total alkalinity, temperature, salinity, nutrients, chlorofluorocarbons, and delta C14. Alain Poisson of Universite Pierre et Marie Curie collected these measurements as part of the World Ocean Circulation Experiment's CO2 survey, which covered approximately 23,000 stations from 94 cruises between 1990 and 1998.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical ocean circulation patterns based on chlorofluorocarbon (CFC) tracer data.
- Studying ocean acidification trends using pH-informative parameters like total alkalinity.
- Investigating nutrient distributions and their relationship to biological productivity in the Southern Ocean.
Strengths
- Data is part of the large-scale World Ocean Circulation Experiment, which covered approximately 23,000 stations.
- Includes multiple key oceanographic variables (DIC, alkalinity, CFCs, nutrients) from a single research cruise.
- Cruise took place over a defined period from 1996-02-20 to 1996-03-31, providing a temporal snapshot.
Limitations
- Last updated 1996-03-31 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.
