Chemical and physical oceanographic data collected from NOAA Ship DISCOVERER in the Gulf of Alaska and North Pacific Ocean from March to April 1991. The dataset includes measurements of dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, isotopes, nutrients, and temperature. Richard A. Feely and John L. Bullister of NOAA's Pacific Marine Environmental Laboratory collected these data as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyzing historical chlorofluorocarbon (CFC) distributions as tracers for ocean circulation patterns.
- Studying nutrient cycles (nitrate, phosphate, silicate) in relation to biological productivity.
- Calibrating climate models with ocean temperature and salinity profiles from the WOCE program.
Strengths
- Data includes multiple key variables for ocean carbon and climate studies, such as dissolved inorganic carbon, CFCs, and stable isotopes.
- Collection was part of the standardized World Ocean Circulation Experiment (WOCE) Hydrographic Program, suggesting consistent methodology.
- The final WOCE collection covers approximately 23,000 stations from 94 cruises, indicating this data is part of a large, coordinated effort.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1991-04-07; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
