June to August 1992 data collection includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and nutrients from the North Atlantic Ocean. Measurements were taken from the R/V HESPERIDES using CTD and bottle instruments by researchers from multiple Spanish and U.S. institutions. This dataset is part of the World Ocean Circulation Experiment (WOCE) A05 survey.
Use Cases
- Modeling ocean acidification by analyzing pH and dissolved inorganic carbon relationships with temperature and salinity.
- Studying carbon sequestration via alkalinity and chlorofluorocarbon (CFC-11, CFC-12) tracer analysis.
- Investigating nutrient cycles by correlating nitrate, nitrite, phosphate, and silicate concentrations with hydrographic data.
- Calibrating ocean carbon models using delta carbon-14 measurements from discrete water samples.
- Characterizing water masses using potential temperature (theta), salinity, and dissolved oxygen profiles.
Strengths
- Data collected during a focused 2-month cruise (1992-06 14 to 1992-08-15) ensuring temporal consistency.
- Includes 15+ key chemical and physical variables per station for multivariate analysis.
- Part of the larger WOCE program, which covered approximately 23,000 stations from 94 cruises globally.
Limitations
- Limited to a single cruise in the North Atlantic Ocean, restricting geographic generalizability.
- Sample size (number of stations/rows) for this specific accession is not provided.
- Data is from 1992, representing a historical snapshot that may not reflect current ocean conditions.
