Partial pressure of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during the R/V Oshoro Maru V cruises in the North Pacific Ocean, Japan and Alaska Coasts in 2023 (NCEI Accession 0304366)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 29, 2026 at 08:34 PM | Dataset Last Updated: May 19, 2025 at 12:00 AM
This dataset includes surface underway chemical, meteorological and physical data collected during the R/V Oshoro Maru V cruises in the North Pacific Ocean, Japan and Alaska Coasts from 2023-02-16 to 2023-12-04. These data include measurements of sea surface temperature (SST), equilibrator temperature (TEQ), equilibrator pressure (PEQ), mole fraction of carbon dioxide (xCO2) in dry air at TEQ, pCO2 at TEQ (PCO2TEQ). The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and Tandem (bubble+mixer) type equilibrator for autonomous CO2 measurement.
