580 paired measurements of oceanic partial pressure of carbon dioxide (pCO2) and total inorganic carbon (TCO2) were collected during the RRS Charles Darwin 58 research cruise. Aida Rios made these measurements in the North Atlantic as part of the World Ocean Circulation Experiment (WOCE). Data collection occurred between April 25 and May 16, 1991.
Use Cases
- Analyze the relationship between computed pCO2 and TCO2 values across the sampled water column.
- Map the spatial distribution of carbon parameters using the provided latitude and longitude coordinates (+39N to +49N, +9W to +28W).
- Study temporal changes in ocean carbon chemistry during the April-May 1991 cruise period.
- Validate or calibrate ocean carbon cycle models for the North Atlantic region using this in-situ measurement set.
Strengths
- Contains 580 paired measurements for pCO2 and TCO2, providing a consistent dataset.
- Clear spatial coverage defined by latitude (+39N to +49N) and longitude (+9W to +28W).
- Precise temporal coverage from April 25 to May 16, 1991.
Limitations
- Relatively small sample size of 580 data points for regional analysis.
- Data is over 30 years old, limiting analysis of recent ocean changes.
- Specific measurement depths within the water column are not detailed in the provided metadata.
