Measurements of oceanic carbon dioxide partial pressure, total inorganic carbon, and ammonium concentrations were collected during the Belgica 9309 research cruise. The cruise, part of the JGOFS and OMEX programmes, took place over 18 days in April and May 1993. Data was gathered by scientists Michel Frankignouelle and Mark Elskens.
Use Cases
- Analyze spatial patterns of pCO2 and TCO2 to study air-sea carbon dioxide exchange along the Iberian Slope.
- Investigate correlations between ammonium (NH4) concentrations and other carbon system parameters to understand nutrient-carbon coupling.
- Use the georeferenced data (+47N to +42N, +7W to +10W) to validate regional ocean biogeochemical models for the North-East Atlantic.
- Study short-term temporal variability of carbon chemistry during the spring period captured by the 1993 cruise timeline.
Strengths
- Includes three distinct, co-located chemical measurements: pCO2, TCO2, and NH4 concentrations.
- Data is precisely geolocated to a specific oceanographic region (Iberian Slope) and time period (19 April - 6 May 1993).
- Collected under established international research programmes (JGOFS and OMEX), ensuring standardized protocols.
Limitations
- Single cruise provides only a temporal snapshot from 1993, limiting analysis of long-term trends.
- Spatial coverage is restricted to a specific transect in the North-East Atlantic, not a broad area.
- Sample size and data resolution (e.g., depth profiles, station count) are unknown from the description.
