Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected f

From March 24 to April 17, 2012, surface underway data were collected aboard the ATLANTIS in the Caribbean Sea and North Atlantic Ocean. The data include air-sea differences in carbon dioxide partial pressure, barometric pressure, salinity, and sea surface temperature, collected using CO2 gas analyzers and equilibrators. Rik Wanninkhof and Robert Castle of NOAA's Atlantic Oceanographic and Meteorological Laboratory collected these data as part of the CLIVAR_A22_2012_UW dataset.

Use Cases

• Modeling air-sea carbon dioxide flux based on partial pressure differences.
• Analyzing the relationship between sea surface temperature and carbon dioxide solubility.
• Studying spatial variability of surface ocean carbon parameters in the Atlantic basin.
• Calibrating and validating ocean carbon cycle models with in-situ underway measurements.

Strengths

• Data covers a specific 25-day cruise in March-April 2012.
• Includes multiple co-measured parameters like salinity, temperature, and barometric pressure.
• Collected by named principal investigators from a NOAA laboratory.

Limitations

• Row count and file size are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2012-04-17; freshness should be verified for current research.
