258 measurements of total inorganic carbon concentration in seawater were collected during the AMT-6 research cruise from May 14 to June 15, 1998. The data was gathered by Carol Robinson as part of the Atlantic Meridional Transect project, with Jim Aiken from PML as the principal scientist. Measurements were taken along a ship track from Cape Town, South Africa, to Grimsby, UK, focusing on the Benguela upwelling region.
Use Cases
- Analyzing spatial gradients in total inorganic carbon concentration across the Atlantic transect from South Africa to the UK.
- Correlating carbon measurements with cruise track location data to study upwelling influences in the Benguela region.
- Using the 1998 carbon dioxide concentration data as a baseline for temporal studies of ocean carbon content change.
Strengths
- 258 discrete in-situ measurements of total inorganic carbon.
- Clear temporal coverage from a specific 33-day research cruise in 1998.
- Geographic coverage spans a major meridional transect of the Atlantic Ocean.
Limitations
- Small sample size of 258 data points for a large ocean region.
- Data is from a single cruise in 1998, limiting temporal analysis.
- No column details or ancillary variables like temperature or salinity are specified in the metadata.
