Surface underway measurements of partial pressure of carbon dioxide (pCO2), sea surface salinity, temperature and other parameters obtained during the ship of opportunity (SOOP) M/S Trans Future-5 cruises in the Pacific Ocean in 2025 (NCEI Accession 0315166)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:47 PM | Dataset Last Updated: May 21, 2026 at 12:00 AM
This dataset includes surface underway, chemical, meteorological and physical data collected from M/S Trans Future 5 in the, North Pacific Ocean, Philippine Sea, Solomon Sea, South Pacific Ocean and Tasman Sea in 2025. These data include absolute humidity, air temperature, air-sea difference - partial pressure of carbon dioxide (pCO2), pCO2 - atmosphere, pCO2 - water, barometric pressure, relative humidity, sea surface salinity, sea surface temperature, wind direction and speed. The instruments used to collect these data include barometric pressure sensor, carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous CO2 measurement and thermosalinographs.
