23,000 stations from 94 World Ocean Circulation Experiment cruises form the basis for this collection. It contains discrete sample and profile measurements of dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorofluorocarbons from the R/V Melville in the Coral Sea and South Pacific Ocean. Data were collected by researchers from Hawaii Pacific University, the Rosenstiel School, and the University of Perpignan between March and June 1994.
Use Cases
- Modeling ocean acidification by analyzing pH and alkalinity trends relative to dissolved inorganic carbon.
- Tracing water mass age and circulation using chlorofluorocarbon-11 (CFC-11) and chlorofluorocarbon-12 (CFC-12) concentrations.
- Studying nutrient cycles and biological productivity through nitrate, phosphate, and silicate measurements.
- Calibrating carbonate system models using paired measurements of dissolved inorganic carbon, alkalinity, and pH.
- Investigating ocean ventilation and mixing processes with helium, neon, tritium, and delta helium-3 tracer data.
Strengths
- Data collection is part of a major global program (WOCE) covering approximately 23,000 stations.
- Includes 19 measured variables spanning chemistry, physics, and tracers for a multi-parameter analysis.
- Profile data from CTD instruments provides vertical resolution of water column properties.
Limitations
- Data is from a single cruise in 1994, offering only a temporal snapshot.
- Geographic coverage is limited to the Coral Sea and South Pacific Ocean for this accession.
- Specific row counts, file formats, and data completeness for this subset are unknown.
