NCEI Accession 0115011 includes chemical, discrete sample, physical and profile data collected from the JOHN P. TULLY research vessel in the North Pacific Ocean, Papahānaumokuākea Marine National Monument and South Pacific Ocean from September to November 1994. The data were collected by C. S. Wong of Fisheries and Oceans Canada; Institute of Ocean Sciences as part of the WOCE_P15Na,b dataset. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program aiming to understand the ocean's role in climate.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon (DIC) and total alkalinity (TA) measurements.
- Analyzing ocean circulation patterns using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
- Studying nutrient cycles in the Pacific Ocean based on nitrate, nitrite, phosphate, and silicate concentrations.
- Calibrating or validating climate models with historical hydrographic profiles of temperature, salinity, and dissolved oxygen.
Strengths
- Data is part of the large-scale World Ocean Circulation Experiment (WOCE), which covered approximately 23,000 stations from 94 cruises.
- Includes a specific suite of key ocean chemistry variables such as DIC, alkalinity, CFCs, and stable isotopes (Delta Carbon-13, Carbon-14).
- Provides discrete sample and profile observations from a defined cruise period (1994-09-06 to 1994-11-10) and geographic regions.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1994-11-10; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
