NOAA Ship Henry B. Bigelow collected these surface underway measurements of carbon dioxide and related variables during four coastal research cruises in 2013. The data include mole fraction of CO2 in seawater and air, sea surface temperature, salinity, and calculated fugacity. Rik Wanninkhof and Denis Pierrot of NOAA's Atlantic Oceanographic and Meteorological Laboratory gathered this data using carbon dioxide gas analyzers and equilibrators.
Use Cases
- Calculate air-sea CO2 flux based on the difference between sea water and air fugacity of CO2.
- Analyze seasonal variability in coastal ocean carbon chemistry based on data collected from March to November 2013.
- Validate regional ocean carbon models using in-situ measurements of mole fraction of CO2 and sea surface salinity.
- Study the relationship between sea surface temperature and the fugacity of CO2 in seawater.
Strengths
- Data collection spans eight months across four distinct research cruises (hb1301-hb1304).
- Includes directly measured variables (e.g., mole fraction of CO2, SST) and derived scientific products (e.g., fugacity of CO2).
- Specific instruments used for collection are named (carbon dioxide gas analyzer, shower head equilibrator).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2013-11-19 00:00:00; freshness should be verified.
