NODC Accession 0114999 contains chemical and physical oceanographic data collected from the R/V James Clark Ross in the South Atlantic Ocean during cruise WOCE_A23 from March to May 1995. The dataset includes measurements of carbon dioxide partial pressure, dissolved inorganic carbon, CFCs, tritium, and other tracers, collected using CTD and bottle instruments. These data were collected by Brian A. King of the National Oceanography Centre, Southampton as part of the World Ocean Circulation Experiment (WOCE), a major climate research program.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and pCO2 measurements.
- Tracing water mass age and circulation using chlorofluorocarbon (CFC) and tritium tracer data.
- Calibrating and validating biogeochemical ocean models with profile data for nutrients like nitrate and phosphate.
- Studying historical baseline conditions for ocean acidification research using carbonate system variables.
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 climate-relevant tracers such as CFC-11, CFC-12, CFC-113, Carbon tetrachloride, and Tritium.
- Collection details are precise, specifying the vessel (JAMES CLARK ROSS), time range (1995-03-20 to 1995-05-06), and principal investigator.
Limitations
- Last updated 1995-05-06; freshness should be verified for contemporary climate studies.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
