Coastal Carbon Dioxide Measurements from NOAA Ship Gordon Gunter, 2012

Surface underway chemical, meteorological, and physical data collected from NOAA Ship GORDON GUNTER in the Coastal Waters of Florida, Mississippi, the Florida Keys National Marine Sanctuary, Gulf of Mexico, and North Atlantic Ocean from 2012-04-29 to 2012-11-20. The data include measurements of partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure, collected using carbon dioxide gas analyzers and equilibrators. Denis Pierrot, Kevin F. Sullivan, and Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) collected this data as part of the Global Coastal Carbon Data Project.

Use Cases

• Modeling air-sea carbon dioxide flux based on the difference in partial pressure between the atmosphere and water.
• Analyzing coastal carbon cycle dynamics based on underway measurements of surface water carbon dioxide.
• Investigating relationships between sea surface temperature, salinity, and carbon dioxide concentrations.
• Assessing seasonal variability in coastal ocean carbon chemistry based on data collected over multiple cruises in 2012.

Strengths

• Data covers multiple distinct coastal regions (Florida, Mississippi, Gulf of Mexico, North Atlantic) over a 7-month period in 2012.
• Includes key variables for carbon cycle studies: partial pressure of CO2 in air and water, salinity, and sea surface temperature.
• Collected by NOAA AOML scientists as part of a defined project (Global Coastal Carbon Data Project) with associated cruise IDs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to the specific ship track and 2012 collection period.
