Fugacity of carbon dioxide (fCO2), temperature, salinity, and other variables collected from surface underway observations using shower head equilibrator, carbon dioxide gas detector and other instruments from NOAA Ship Oscar Dyson cruises in the North Pacific Ocean, Gulf of Alaska, Bering Sea in 2025 (NCEI Accession 0315072)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:46 PM | Dataset Last Updated: May 21, 2026 at 12:00 AM

This dataset contains surface underway measurements of fugacity of carbon dioxide (fCO2), sea surface salinity, sea surface temperature, and other parameters collected during the NOAA Ship Oscar Dyson cruises in the North Pacific Ocean, Gulf of Alaska, Bering Sea, from 2025-04-25 to 2025-09-18. This effort was conducted in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).
