Eastern Tropical Atlantic Ocean Carbon Chemistry Profiles from 2014 PIRATA Cruise

Discrete seawater profile measurements of dissolved inorganic carbon and total alkalinity collected during a French PIRATA research cruise. The dataset includes temperature and salinity data from the Eastern Tropical Atlantic Ocean, gathered between April 10 and May 19, 2014. Samples were analyzed using a potentiometric titration method calibrated with Certified Reference Material.

Use Cases

• Modeling ocean acidification trends based on discrete DIC and alkalinity measurements.
• Analyzing carbonate system variability in the Eastern Tropical Atlantic based on profile data.
• Calibrating continuous sensor data using discrete sample reference points mentioned in the description.
• Studying the relationship between temperature, salinity, and carbon chemistry in a tropical ocean setting.

Strengths

• Data collected during a dedicated PIRATA oceanographic research cruise.
• Analytical method uses Certified Reference Material for calibration, as stated in the description.
• Covers a specific temporal range from 2014-04-10 to 2014-05-19.
• Includes four key oceanographic variables: DIC, alkalinity, temperature, and salinity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 2014, limiting temporal generalizability.
