Partial pressure of carbon dioxide, salinity, temperature and other variables collected from surface underway observations from R/V F.G. Walton Smith coastal cruises in the North Atlantic Ocean and Gulf of America in 2025 (NCEI Accession 0312676)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:44 PM | Dataset Last Updated: February 20, 2026 at 12:00 AM
This dataset includes surface underway, chemical, meteorological and physical data collected from R/V F.G. Walton Smith in the North Atlantic Ocean and Gulf of America (Gulf of Mexico) in 2025. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), pCO2 in atmosphere, pCO2 in water, barometric pressure, sea surface salinity and temperature. The instruments used to collect these data include barometric pressure sensor, carbon dioxide gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide measurement and thermosalinographs. The Global Coastal Carbon Data Project data includes the bottle (discrete) and surface (underway) carbon-related measurements from coastal research cruises, the data from time series cruises and coastal moorings. The coastal regions data are very important for the understanding of carbon cycle on the continental margins.
