NCEI Accession 0116640 includes discrete sample and profile data collected from the research vessel POLARSTERN in the Indian Ocean, South Atlantic Ocean, and Southern Oceans from March to May 1996. The dataset contains measurements for dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nutrients, and other hydrographic variables. These data were collected by researchers from the Alfred Wegener Institute and the Royal Netherlands Institute for Sea Research as part of the WOCE_S04A_ANTXIII_4 cruise.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon (DIC) and chlorofluorocarbon (CFC) tracer data.
- Analyzing water mass properties and circulation in the Southern Oceans based on salinity, potential temperature, and dissolved oxygen profiles.
- Studying nutrient distributions and biogeochemical cycles in polar oceans based on nitrate, phosphate, and silicate measurements.
- Investigating temporal changes in ocean chemistry by comparing this historical dataset with modern re-occupation surveys.
Strengths
- Includes 18 distinct measured variables covering carbon chemistry, tracers, nutrients, and physical oceanography.
- Data collected during a dedicated research cruise (WOCE_S04A_ANTXIII_4) in a targeted region (Southern Oceans >60 degrees South).
- Associated with the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program, suggesting a standardized collection protocol.
Limitations
- Last updated 1996-05-20 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.
