Belgica 9521 research cruise data contains 113 measurements of seawater partial pressure of carbon dioxide (pCO2) and total inorganic carbon (TCO2), plus 74 measurements of ammonium (NH4) concentration. The data was collected by researchers Michel Frankignoulle and Marc Elskens for the JGOFS and OMEX programmes. Measurements were taken in the North-East Atlantic during a cruise from September 11 to 20, 1995.
Use Cases
- Analyze the relationship between pCO2 and TCO2 computed from pH and alkalinity across 113 sampling points.
- Model spatial distributions of ammonium concentration from 74 manual colorimetric analysis samples.
- Validate regional ocean carbon models using in-situ pCO2 data from the +47N to +50N, +7W to +11W region.
- Study short-term biogeochemical variability during the September 1995 cruise period across the water column.
Strengths
- 113 paired measurements for pCO2 and TCO2 provide a consistent carbon system view.
- 74 ammonium measurements offer a complementary nutrient dataset from the same cruise.
- Precise spatial (+47N to +50N, +7W to +11W) and temporal (September 11-20, 1995) bounds are documented.
Limitations
- Sample size is limited to 113 carbon measurements and 74 nutrient measurements.
- Data is from a single, short cruise in 1995, limiting temporal and seasonal analysis.
- Method details for 'computing from pH and alkalinity' and specific water column depths are not provided in the description.
