The Indian Ocean cruise WOCE_S04I collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, pCO2, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons, helium, and carbon isotopes. These data were collected by researchers from Columbia University and the Rosenstiel School of Marine and Atmospheric Science as part of the World Ocean Circulation Experiment between May and July 1996. The final WOCE collection covers approximately 23,000 stations from 94 cruises conducted between 1990 and 1998.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical ocean carbon chemistry trends based on time-series data from the 1990s.
- Studying ocean circulation and mixing using correlated temperature, salinity, and tracer data.
- Investigating anthropogenic carbon penetration into the ocean based on chlorofluorocarbon (CFC) profiles.
- Calibrating and validating global carbon cycle models using in-situ pCO2 and isotope measurements.
Strengths
- Data is part of the large-scale World Ocean Circulation Experiment, covering approximately 23,000 stations from 94 cruises.
- Includes multiple correlated variables for carbon cycle studies, such as DIC, alkalinity, pCO2, nutrients, and tracers.
- Cruise provides a specific temporal snapshot (May-July 1996) within a known program timeframe (1990-1998).
Limitations
- Last updated 1996-07-04 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count for this specific accession is unknown, which may limit suitability assessment.
