NOAA Ship Henry B. Bigelow 2019 Coastal Surface Underway Carbon Data

Surface underway data from NOAA Ship Henry B. Bigelow includes measurements of mole fraction of carbon dioxide (CO2) in air and water, barometric pressure, sea surface temperature, and salinity collected between March 8 and November 12, 2019. The Ocean Carbon Group at NOAA's Atlantic Oceanographic and Meteorological Laboratory installed the carbon dioxide gas analyzer and equilibrator on the vessel in February 2011. The dataset captures chemical, meteorological, and physical variables along the US Northeast coast in the North Atlantic Ocean.

Use Cases

• Calculating air-sea CO2 flux based on the difference between sea water fugacity of CO2 (fCO2) and interpolated air fCO2.
• Monitoring ocean acidification trends using sea surface temperature, salinity, and fugacity of CO2 in sea water.
• Correlating meteorological conditions with carbon measurements using barometric pressure data corrected to sea level.
• Assessing spatial variability of carbon parameters in coastal waters from underway surface observations.

Strengths

• Data covers a continuous eight-month time range from 2019-03-08 to 2019-11-12.
• Includes specific, calibrated measurements like fugacity of CO2 in sea water at SST and 100% humidity.
• Instrumentation details are provided: carbon dioxide gas analyzer and shower head chamber equilibrator.

Limitations

• Column names and dataset size (rows, file size) are unknown across all sources.
• Metadata conflicts exist: the 'last updated' date is reported as both 2026-03-05 and 2019-11-12.
• License information is not provided, restricting clarity on reuse permissions.
