Ocean Carbon and Hydrographic Measurements from WOCE Cruises, 1993

Surface and profile data from the Bismarck Sea, Coral Sea, and other ocean basins collected aboard the THOMAS G. THOMPSON from October 5 to November 10, 1993. The dataset includes measurements of carbon dioxide partial pressure, dissolved inorganic carbon, alkalinity, salinity, temperature, nutrients, and chlorofluorocarbons. It was collected by researchers from Princeton University and NOAA as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program.

Use Cases

• Modeling ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing historical ocean acidification trends using partial pressure of carbon dioxide data.
• Studying deep ocean circulation patterns using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
• Calibrating contemporary ocean carbon models against this 1993 baseline dataset.

Strengths

• Data covers multiple ocean basins including the North Atlantic, North Pacific, and South Pacific.
• Includes a wide range of chemical, physical, and meteorological variables (e.g., CFCs, nutrients, isotopes).
• Part of the large-scale World Ocean Circulation Experiment (WOCE), which covered approximately 23,000 stations.

Limitations

• Last updated 1993-11-10 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.
