NODC Accession 0115013 contains chemical and physical oceanographic data from the WOCE_S04P cruise aboard the AKADEMIK IOFFE in the South Pacific Ocean from February to April 1992. The data includes measurements of carbon dioxide partial pressure, dissolved inorganic carbon, CFCs, stable isotopes, and nutrients collected via CTD and bottle casts. These data were collected by Taro Takahashi of Columbia University's Lamont-Doherty Earth Observatory as part of the World Ocean Circulation Experiment.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon and pCO2 measurements.
- Studying ocean ventilation rates using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
- Analyzing water mass properties and circulation from temperature, salinity, and nutrient profiles.
- Calibrating or validating global ocean biogeochemical models with in-situ carbon and isotope data.
Strengths
- Data collection is part of the major World Ocean Circulation Experiment (WOCE), a cornerstone of climate research.
- Includes a wide array of co-located variables (carbon species, CFCs, isotopes, nutrients, physical properties) for integrated analysis.
- Covers a specific, well-documented research cruise (WOCE_S04P) with a clear temporal (1992-02-14 to 1992-04-06) and spatial (South Pacific Ocean) scope.
Limitations
- Last updated 1992-04-06 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
