June 1997 data from the Belgica 9714C research cruise on the Iberian Slope, North-East Atlantic. It contains 247 measurements each of seawater pCO2 and total inorganic carbon, plus 174 ammonium concentration measurements from two analytical methods. The data was collected by researchers Michel Frankignoulle, Marc Elskens, and Xose Salgado Alvarez as part of the JGOFS and OMEX programs.
Use Cases
- Analyze the relationship between pCO2 and total inorganic carbon (TCO2) across the sampled water column.
- Compare ammonium concentrations from manual colorimetric analysis versus filtration/autoanalysis methods.
- Map the spatial distribution of carbon parameters within the +42N to +43N, +9W to +10W study area.
- Investigate short-term variability in oceanic carbon dioxide partial pressure during the June 1997 cruise period.
Strengths
- 247 paired measurements for key carbon parameters (pCO2 and TCO2) enabling direct correlation.
- Precise spatial (+42N to +43N, +9W to +10W) and temporal (21-30 June 1997) coverage documented.
- Ammonium data provided from two distinct analytical techniques (21 manual and 153 autoanalyzed samples).
Limitations
- Limited temporal scope to a single 10-day cruise in June 1997.
- Sample size for ammonium measurements (n=174) is smaller than for carbon parameters.
- Geographic coverage is restricted to a specific transect on the Iberian Slope.
