Coastal Surface Carbon Dioxide Measurements from NOAA Ship Henry B. Bigelow, 2017

2017 surface underway data collected from NOAA Ship Henry B. Bigelow operating in the North Atlantic Ocean between North Carolina and Maine. The dataset includes measurements of mole fraction of CO2 in water and air, sea surface temperature, salinity, and fugacity of CO2. Data were collected by Rik Wanninkhof and Denis Pierrot of NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of research cruises HB1701 through HB1704.

Use Cases

• Modeling air-sea CO2 flux based on fugacity difference measurements.
• Analyzing seasonal carbon dynamics in coastal waters based on sea surface temperature and salinity data.
• Calibrating or validating ocean acidification models based on in-situ CO2 mole fraction measurements.

Strengths

• Data collected during seven distinct research cruise legs (HB1701, HB1702-Leg1-4, HB1703, HB1704) in 2017.
• Includes multiple related variables: CO2 mole fraction in water and air, sea surface temperature, salinity, and barometric pressure.
• Collected by NOAA's Atlantic Oceanographic and Meteorological Laboratory, a recognized authority in ocean carbon research.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the ship's operational area between North Carolina and Maine.
