Chemical and physical oceanographic data collected from multiple research vessels across global seas between 1983 and 1998. The collection includes measurements of dissolved inorganic carbon, alkalinity, nutrients, and temperature, taken using CTD and bottle instruments. Charles D. Keeling and Peter Guenther of Scripps Institution of Oceanography collected these data as part of the Keeling Shore Based Carbon Analyses and the World Ocean Circulation Experiment (WOCE) CO2 survey.
Use Cases
- Modeling oceanic carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions (nitrate, phosphate, silicate) in relation to ocean circulation.
- Studying long-term changes in ocean chemistry and temperature across multiple basins.
- Calibrating global carbon cycle models using the extensive station coverage from 94 WOCE cruises.
Strengths
- Data spans a 15-year period (1983-10-10 to 1998-10-20), providing a long-term observational record.
- Coverage includes approximately 23,000 stations from 94 distinct research cruises.
- Samples were collected across a wide geographic range, including the Indian Ocean, Atlantic Ocean, Pacific Ocean, and others.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-10-20 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
