In 2017, surface underway data were 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 barometric pressure. These data were collected by Rik Wanninkhof and Denis Pierrot of NOAA's Atlantic Oceanographic and Meteorological Laboratory during seven research cruise legs.
Use Cases
- Modeling air-sea CO2 flux based on fugacity difference measurements.
- Analyzing seasonal or spatial variability in coastal carbon chemistry based on sea surface temperature and salinity.
- Calibrating or validating satellite-derived ocean carbon products based on in-situ surface underway observations.
- Studying the relationship between meteorological conditions and surface ocean CO2 partial pressure based on barometric pressure data.
Strengths
- Data collection spans seven distinct cruise legs (HB1701 through HB1704) in 2017, providing temporal coverage.
- Measurements include multiple related variables (CO2 mole fraction, temperature, salinity, pressure) for integrated analysis.
- Instruments used are specified as a carbon dioxide gas analyzer and shower head chamber equilibrator.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2017-07-19 00:00:00; freshness should be verified.
