North Atlantic Ocean data contains 75 measurements of partial pressure of carbon dioxide (pCO2) and 83 measurements of total inorganic carbon (TCO2) concentration in the water column. Measurements were made by researchers Andy Watson and Peter Williams during the RRS Discovery 190 research cruise from April 18 to April 30, 1990.
Use Cases
- Analyze spatial patterns of pCO2 and TCO2 within the +48N to +50N, +18W to +21W cruise track.
- Calculate air-sea CO2 flux gradients using pCO2 measurements from the water column.
- Correlate TCO2 concentration measurements with other oceanographic parameters from the BOFS study.
- Validate or calibrate regional ocean carbon cycle models for the North Atlantic in April 1990.
Strengths
- 158 total data points (75 pCO2, 83 TCO2) from a dedicated research cruise.
- Precise spatial and temporal coverage: April 18-30, 1990, within a defined 2x3 degree region.
Limitations
- Small sample size of 158 total measurements limits statistical power.
- Data is from a single, short-duration cruise in one season, not a long-term time series.
- Geographic scope is limited to a specific transect in the North Atlantic.
