Surface underway data collected from the research vessel Skogafoss across the Labrador Sea, North Atlantic Ocean, North Greenland Sea, and Norwegian Sea from 2014-03-17 to 2015-01-14. The data include partial pressure of carbon dioxide in air and water, barometric pressure, salinity, and sea surface temperature. Rik Wanninkhof, Denis Pierrot, and Kevin Sullivan of NOAA's Atlantic Oceanographic and Meteorological Laboratory collected the data using barometric pressure sensors, carbon dioxide gas analyzers, and thermosalinographs.
Use Cases
- Calculate air-sea CO2 flux based on the difference in partial pressure between the atmosphere and water.
- Analyze seasonal variability of surface ocean carbon dioxide concentrations across high-latitude seas.
- Correlate sea surface temperature and salinity with carbon dioxide partial pressure in surface waters.
- Validate and calibrate regional or global carbon cycle models using in-situ underway measurements.
Strengths
- Data collected over a 10-month period from March 2014 to January 2015, providing seasonal coverage.
- Includes directly measured, co-located variables: CO2 partial pressure in air and water, barometric pressure, salinity, and sea surface temperature.
- Covers a specific geographic transect across four distinct marine regions: Labrador Sea, North Atlantic Ocean, North Greenland Sea, and Norwegian Sea.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2015-01-14; freshness should be verified for contemporary climate studies.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
