23,000 stations from 94 WOCE cruises form the final collection for this ocean carbon survey. This dataset includes discrete sample, profile, and underway-surface observations of carbon dioxide, dissolved inorganic carbon, alkalinity, and other variables collected from the R/V Knorr in the North and South Atlantic Ocean during April and May 1994. The data were collected by Catherine Goyet of the University of Perpignan as part of the World Ocean Circulation Experiment (WOCE).
Use Cases
- Modeling ocean carbon sequestration based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
- Analyzing ocean acidification trends based on alkalinity and pH-related variables.
- Studying ocean circulation and water mass properties using temperature, salinity, and chlorofluorocarbon (CFC) tracer data.
- Calibrating and validating Earth system models with in-situ carbon chemistry profile data.
Strengths
- Final collection covers approximately 23,000 stations from 94 WOCE cruises, providing broad spatial coverage.
- Includes data from multiple measurement types (discrete sample, profile, underway-surface) and instruments (CTD, CO2 gas analyzer).
- Part of the standardized World Ocean Circulation Experiment (WOCE) Hydrographic Program, suggesting consistent collection protocols.
Limitations
- Last updated 1994-05-21; freshness should be verified for contemporary climate studies.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count for this specific cruise is unknown, which may limit suitability assessment.
