From March 8 to April 11, 2016, discrete seawater samples were collected from the R/V Thalassa during the French PIRATA cruise in the Eastern Tropical Atlantic Ocean. The dataset likely contains measurements of dissolved inorganic carbon, total alkalinity, temperature, and salinity. The National Oceanic and Atmospheric Administration published this data, which was last updated on March 5, 2026.
Use Cases
- Calculate ocean acidification rates based on dissolved inorganic carbon and alkalinity measurements.
- Model carbon flux in the tropical Atlantic based on surface chemistry data.
- Validate satellite-derived salinity estimates based on discrete surface salinity measurements.
- Study seasonal variability in ocean chemistry based on the March-April 2016 time range.
Strengths
- Data collection spans a specific cruise period from March 8 to April 11, 2016.
- Measurement methods are described, referencing the potentiometric titration of Edmond (1970) and calibration with Certified Reference Material.
- The dataset was last updated on March 5, 2026, suggesting ongoing curation.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single cruise in the Eastern Tropical Atlantic.
