NODC Accession 0115156 includes chemical and physical oceanographic data collected from the R/V Knorr in the North and South Pacific Ocean between October 1992 and April 1993. The data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory as part of the World Ocean Circulation Experiment Hydrographic Program. It contains measurements for carbon dioxide partial pressure, dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nutrients, and other variables.
Use Cases
- Calibrating ocean carbon cycle models based on dissolved inorganic carbon and CO2 fugacity measurements.
- Studying ocean ventilation and water mass age using tracer data like CFC-11, CFC-12, and Tritium.
- Analyzing historical nutrient distributions (nitrate, phosphate, silicate) in the Pacific Ocean.
- Investigating the relationship between potential temperature, salinity, and carbon system variables.
Strengths
- Data collection is part of the large-scale World Ocean Circulation Experiment, which covered approximately 23,000 stations from 94 cruises.
- Includes a wide range of co-located variables (e.g., carbon system, nutrients, tracers, physical properties) from a single cruise series.
- Associated with a specific, documented research vessel (KNORR) and time period (1992-10-06 to 1993-04-13).
Limitations
- Last updated 1993-04-13 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.
