July 1997 data from the Belgica 9714D research cruise in the Bay of Biscay contains 44 paired measurements of seawater pCO2 and total inorganic carbon concentration. The dataset was created by researcher Michel Frankignoulle as part of the JGOFS and OMEX international programs. Measurements were computed from in-situ pH and alkalinity readings.
Use Cases
- Analyze the relationship between computed pCO2 and computed total inorganic carbon (TCO2) across 44 sampling points.
- Model spatial gradients of carbon parameters within the +47N to +48N, +7W study area during July 1997.
- Use the 44 pCO2 measurements to estimate air-sea CO2 flux in the North-East Atlantic coastal region.
- Correlate cruise-based TCO2 concentrations with broader JGOFS and OMEX program data for the ocean margin.
- Validate computational methods for deriving pCO2 and TCO2 from paired pH and alkalinity measurements.
Strengths
- 44 paired measurements of pCO2 and TCO2 provide a consistent snapshot.
- Precise temporal (July 2-7, 1997) and spatial (+47N to +48N, +7W) coverage for the cruise.
Limitations
- Small sample size of 44 data points limits statistical power for broad conclusions.
- Data is from a single, brief cruise in one season, lacking temporal or inter-annual variability.
- Potential computational uncertainties inherited from deriving values from pH and alkalinity.
