254 measurements of seawater partial pressure of carbon dioxide (pCO2) and total inorganic carbon (TCO2), plus 14 ammonium (NH4) concentration measurements, were collected during the Belgica 9919B research cruise. The data were produced by scientists Michel Frankignoulle and Marc Elskens as part of the JGOFS and OMEX programs. The cruise took place in September 1999 along the Iberian Slope in the North-East Atlantic.
Use Cases
- Analyze the relationship between computed pCO2 and TCO2 measurements to study carbon system thermodynamics in coastal waters.
- Model spatial gradients of ammonium concentration (NH4) against latitude and longitude to identify nutrient sources on the Iberian Slope.
- Calibrate regional ocean carbon models using the 254-point high-resolution transect of pCO2 and TCO2 data from the cruise track.
- Investigate short-term temporal variability in carbon parameters during the September 1999 cruise period across the defined spatial grid.
Strengths
- 254 paired measurements for pCO2 and TCO2 provide a detailed spatial transect.
- Precise geospatial bounding box defined from +42N to +43N and +9W to +10W.
- Data collected under established international scientific programs (JGOFS and OMEX).
Limitations
- Ammonium (NH4) measurements are limited to only 14 data points.
- Dataset is temporally limited to a single one-week cruise in September 1999.
- Sample size for core carbon parameters, while good for a cruise, is modest for machine learning applications.
