Discrete surface measurements of dissolved inorganic carbon, total alkalinity, temperature, and salinity were collected during the French PIRATA cruise aboard the R/V Thalassa. The cruise occurred in the Eastern Tropical Atlantic Ocean from March 18 to April 15, 2015. The National Oceanic and Atmospheric Administration published the data, which includes seawater samples analyzed using a potentiometric titration method calibrated with Certified Reference Material.
Use Cases
- Modeling ocean acidification based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing surface water chemistry variability based on discrete sample data.
- Calibrating continuous sensor data based on discrete reference measurements.
- Studying carbon cycle dynamics in the tropical Atlantic based on cruise-collected data.
Strengths
- Data collection covers a specific cruise period from 2015-03-18 to 2015-04-15.
- Measurement methods are described, including use of Certified Reference Material for calibration.
- The dataset is published by the National Oceanic and Atmospheric Administration.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
