January 25 to February 19, 1994 measurements collected from the R/V Thomas G. Thompson in the South Pacific Ocean. The dataset includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorofluorocarbons. Data were gathered by Christopher D. Winn of Hawaii Pacific University as part of the World Ocean Circulation Experiment (WOCE) P31 cruise.
Use Cases
- Calculate ocean acidification metrics by correlating pH and dissolved inorganic carbon measurements with temperature and salinity.
- Study deep water formation and circulation using potential temperature (theta), salinity, and chlorofluorocarbon (CFC-11, CFC-12) tracer profiles.
- Model marine nutrient cycles by analyzing nitrate, nitrite, phosphate, and silicate concentrations alongside hydrostatic pressure data.
- Assess seawater carbonate system equilibrium using paired alkalinity and dissolved inorganic carbon measurements.
- Investigate oxygen minimum zones through dissolved oxygen profiles correlated with nutrient and temperature data.
Strengths
- Multivariate profile data includes 14 key chemical and physical parameters per observation.
- Data is part of the larger WOCE final collection covering approximately 23,000 stations from 94 cruises.
- Measurements were taken using standardized CTD and bottle instruments during a dedicated research cruise.
Limitations
- Temporal coverage is limited to a single 26-day cruise in early 1994.
- Geographic coverage is restricted to the specific track of the P31 cruise in the South Pacific Ocean.
- Sample size (number of stations or rows) for this specific accession is not provided.
