Eastern Tropical Atlantic Ocean seawater samples collected from the R/V Le Suroit French PIRATA cruise between May 3 and May 25, 2011. The dataset consists of discrete surface measurements of dissolved inorganic carbon, total alkalinity, temperature, and salinity. Samples were analyzed using a potentiometric titration method calibrated with Certified Reference Material.
Use Cases
- Modeling ocean acidification trends based on discrete surface measurements of dissolved inorganic carbon and alkalinity
- Analyzing seawater carbonate system variability based on concurrent temperature and salinity data
- Calibrating oceanographic sensors based on certified reference material calibration methods described
- Studying spatial patterns of marine chemistry in the Eastern Tropical Atlantic Ocean based on cruise track data
Strengths
- Data collected during a dedicated scientific cruise (PIRATA) over a defined period from May 3 to May 25, 2011
- Measurement methods are specified, including potentiometric titration and use of Certified Reference Material for calibration
- Dataset includes multiple concurrent oceanographic parameters (DIC, alkalinity, temperature, salinity)
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Data may reflect geographic and temporal bias inherent to a single cruise in 2011
