Pacific, Atlantic, Indian Oceans and Gulf of Mexico surface water measurements from 21 cruises between 1991-07-12 and 2020-04-15. The dataset consists of co-located discrete and underway measurements of fugacity of CO2 (fCO2), alkalinity, and total dissolved inorganic carbon. It was published by the National Oceanic and Atmospheric Administration to infer the temperature dependence of CO2 fugacity in seawater.
Use Cases
- Calculate temperature dependence of CO2 fugacity based on co-located discrete and underway fCO2 measurements.
- Validate empirical models of CO2 solubility using alkalinity and total dissolved inorganic carbon data.
- Analyze spatial and temporal trends in surface ocean CO2 fugacity across major ocean basins.
- Compare calculated fCO2 values from TA and DIC with direct fCO2 measurements.
Strengths
- Data spans 21 cruises over a 29-year period from 1991 to 2020.
- Includes co-located discrete and underway measurements for direct comparison.
- Provides calculated fCO2 from alkalinity and total dissolved inorganic carbon.
- Geographic coverage includes Pacific, Atlantic, Indian Oceans and Gulf of Mexico.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic/temporal bias inherent to cruise-based sampling.
