North Pacific Ocean Carbon Chemistry and Hydrographic Profiles from 1993

WOCE_P01W includes discrete sample and profile data collected from the AKADEMIK ALEKSANDR NESMEYANOV research vessel in the North Pacific Ocean and Sea of Okhotsk from 1993-08-08 to 1993-09-21. C. S. Wong of Fisheries and Oceans Canada collected these data, which include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorofluorocarbons. The dataset is part of the World Ocean Circulation Experiment (WOCE), a major climate research program running from 1990 to 1998.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) and tritium data.
• Analyzing nutrient dynamics in the North Pacific based on nitrate, nitrite, phosphate, and silicate concentrations.
• Calibrating hydrographic models using concurrent measurements of temperature, salinity, and dissolved oxygen.

Strengths

• Data collection is part of the standardized World Ocean Circulation Experiment (WOCE) program, which covered approximately 23,000 stations from 94 cruises.
• Includes a multi-parameter suite of 17+ chemical and physical variables measured from discrete bottle samples and CTD profiles.
• Cruise and collection dates (1993-08 08 to 1993-09-21) and geographic scope (North Pacific Ocean and Sea of Okhotsk) are explicitly defined.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to a single cruise in 1993.
