Partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon, pH, alkalini

23,000 stations from 94 WOCE cruises form the final collection of this major climate research program. This dataset includes discrete chemical and physical measurements from the R/V Knorr in the Caribbean Sea and North Atlantic Ocean between November 1996 and September 1997. Data were collected by researchers from Columbia University, Rosenstiel School of Marine and Atmospheric Science, and Universitat Kiel as part of the World Ocean Circulation Experiment Hydrographic Program.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon and partial pressure of CO2 measurements
• Analyzing water mass circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracer data
• Studying ocean acidification trends based on pH and alkalinity observations
• Calibrating biogeochemical models with nutrient profiles (nitrate, phosphate, silicate)

Strengths

• Part of the extensive World Ocean Circulation Experiment, covering approximately 23,000 stations from 94 cruises
• Includes a wide range of chemical tracers relevant for climate studies, such as CFCs, delta Carbon-13, delta Carbon-14, and Tritium
• Data collection involved multiple established research institutions including Columbia University and the Rosenstiel School

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Last updated 1997-09-03; freshness should be verified for contemporary climate studies
• Row count for this specific accession is unknown, which may limit suitability assessment
