Surface underway measurements of fugacity of carbon dioxide (fCO2, seawater and atmospheric), water temperature, and salinity from 3 cruises in the equatorial Pacific Ocean, collected onboard NOAA Ship Ka'imimoana in 1999 (NCEI Accession 0268311)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2022-11-04T00:00:00.000+00:00
This dataset contains data from underway fCO2 (seawater and atmospheric), water temperature, and salinity measurements collected on 3 equatorial Pacific cruises from 1999-01-30 to 1999-07-26 as part of a ship-of-opportunity time-series. Cruise names and EXPOCODEs: KA1999_01 (33KM19990130), KA1999_02 (33KM19990506),KA1999_03 (33KM19990708). Since 1982, NOAA's Pacific Marine Environmental Laboratory has made underway CO2 observations in the equatorial Pacific as a companion project to the Global Tropical Moored Buoy Array. This effort was conducted with the support of NOAA's Global Ocean Monitoring and Observing Program.
