Discrete chemical and physical measurements from the Hudson research vessel during the World Ocean Circulation Experiment's A01W cruise in June-July 1995. The data includes dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, and temperature-salinity profiles collected using CTD and bottle instruments. E. Peter Jones of the Bedford Institute of Oceanography collected these samples as part of a global CO2 survey spanning 23,000 stations from 94 WOCE cruises between 1990 and 1998.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
- Tracking anthropogenic tracer dispersion based on chlorofluorocarbon (CFC-11, CFC-12, CFC-113) and methyl chloroform concentrations.
- Analyzing water mass properties and circulation based on potential temperature, salinity, and hydrostatic pressure profiles.
- Studying nutrient dynamics in ocean ecosystems based on nitrate+nitrite, phosphate, and silicate content.
Strengths
- Data is part of the major World Ocean Circulation Experiment (WOCE) program, which collected approximately 23,000 stations globally.
- Includes multiple key variables for climate studies: dissolved inorganic carbon, alkalinity, CFCs, nutrients, and physical properties.
- Specific cruise (WOCE_A01W) and collection period (1995-06-07 to 1995-07-05) are clearly documented.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
- Data may reflect temporal bias inherent to a single cruise in 1995.
