Surface Ocean Carbon Dioxide and Salinity Measurements from the S.A. Agulhas II, July 2016

NCEI Accession 0160557 contains surface underway chemical, meteorological, and physical data collected from the S.A. AGULHAS II research vessel in the South Atlantic Ocean between July 15 and July 27, 2016. The dataset includes measurements of barometric pressure, partial pressure of carbon dioxide in the atmosphere and water, and salinity. These data were collected by researchers from the Council for Scientific and Industrial Research using barometric pressure sensors and carbon dioxide gas analyzers.

Use Cases

• Calculate air-sea carbon dioxide flux based on partial pressure measurements.
• Analyze correlations between atmospheric pressure and oceanic carbon dioxide levels.
• Study spatial variability of surface ocean salinity and carbon chemistry in the South Atlantic.
• Validate or calibrate ocean carbon cycle models using in-situ underway observations.

Strengths

• Data covers a specific 13-day research cruise with precise temporal bounds.
• Includes concurrent measurements of atmospheric and aquatic carbon dioxide partial pressure.
• Data originates from a recognized research vessel and is archived by NOAA NCEI.

Limitations

• Row count and file format are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2016-07-27; freshness should be verified for current research.
