112 paired measurements of seawater pCO2 and total inorganic carbon, plus 89 ammonium concentration measurements, were collected during the Belgica 9322A cruise in September 1993. Scientists Michel Frankignoulle and Marc Elskens gathered this data for the JGOFS and OMEX programs. The cruise covered a specific region of the North-East Atlantic over a nine-day period.
Use Cases
- Analyze the relationship between pCO2 and total inorganic carbon (TCO2) concentrations across the sampled stations.
- Model spatial gradients of ammonium (NH4) concentration within the +48N to +50N, +7W to +13W study area.
- Calculate air-sea CO2 flux estimates using the in-situ pCO2 measurements from the cruise track.
- Correlate nutrient (NH4) data with carbon system parameters (pCO2, TCO2) to study biogeochemical coupling.
Strengths
- 112 paired pCO2 and TCO2 measurements provide a consistent carbon system view.
- Precise spatial and temporal bounds: data from a 9-day cruise in a defined Atlantic sector.
Limitations
- Limited sample size with 112 carbon measurements and 89 ammonium measurements.
- Data is from a single snapshot in time (September 1993), limiting temporal trend analysis.
- Geographic scope is restricted to a specific transect in the North-East Atlantic.
