Measurements of oceanic carbon dioxide were collected during the Belgica 9815D research cruise in the Bay of Biscay. The dataset contains 13 measurements each for partial pressure of carbon dioxide (pCO2) and total inorganic carbon (TCO2), computed from pH and alkalinity. Data was gathered by Michel Frankignoulle as part of the JGOFS and OMEX programmes during a cruise from July 10 to 14, 1998.
Use Cases
- Analyze the relationship between pCO2 and TCO2 measurements to study carbon system thermodynamics.
- Model spatial carbon distribution using the +48N, -7W geographic coordinate from the cruise track.
- Validate regional carbon flux models using in-situ pCO2 data from the Bay of Biscay.
- Study short-term carbon variability using the time-series data collected over the 5-day cruise period.
Strengths
- Data includes 13 discrete, co-located measurements for both pCO2 and TCO2 parameters.
- Clear temporal coverage from July 10 to July 14, 1998.
- Specific geographic location provided (+48N latitude, -7W longitude).
Limitations
- Very small sample size of only 13 data points for each variable.
- Data is from a single, brief 5-day cruise, limiting temporal and spatial representativeness.
- Variables are computed from pH and alkalinity rather than direct measurements, introducing potential calculation errors.
