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. These data include dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, nutrients, and other variables, collected as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyzing historical chlorofluorocarbon (CFC) distributions as tracers of ocean circulation.
- Studying nutrient cycling in ocean ecosystems based on nitrate, nitrite, phosphate, and silicate data.
- Calibrating and validating ocean biogeochemical models using a suite of co-located chemical and physical variables.
Strengths
- Data is part of the large-scale World Ocean Circulation Experiment (WOCE), which covered approximately 23,000 stations.
- Includes a co-located suite of 17 key chemical and physical variables relevant to ocean carbon and climate studies.
- Provides precise temporal and geographic context: a single cruise from August to September 1993 in the North Pacific and Sea of Okhotsk.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1993-09-21; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
