Surface underway measurements of partial pressure of carbon dioxide (pCO2), sea surface temperature, sea surface salinity and barometric pressure during R/V Nathaniel B. Palmer Expeditions in the Southern Ocean, South Pacific Ocean, Drake Passage in 2025 (NCEI Accession 0312069)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:18 AM | Dataset Last Updated: January 30, 2026 at 12:00 AM

This dataset includes surface underway data collected from R/V Nathaniel B. Palmer in the South Pacific Ocean, Drake Passage and Southern Ocean from 2025-02-14 to 2025-05-15. These data include barometric pressure, partial pressure carbon dioxide (pCO2) - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
