High-resolution ocean and atmosphere pCO2 time-series measurements from mooring TAO165E8S in the Equatorial Pacific Ocean (NCEI Accession 0117073)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 02:30 AM | Dataset Last Updated: January 26, 2026 at 12:00 AM
This dataset includes chemical, meteorological, physical and time series data collected from Mooring_TAO165E_8S in the Equatorial Pacific Ocean from 2009-06-22 to 2022-06-12. These data include air-sea difference - partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 - atmosphere, pCO2 - water, salinity and sea surface temperature. The Moored Autonomous pCO2 (MAPCO2®) instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter. The Global CO2 Time-series and Moorings Project involves international groups from 18 countries who have mounted sensors on moored buoys to provide high resolution time-series measurements of atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). The CO2 Time-series and Moorings Project is coordinated by UNESCO International Ocean Carbon Coordination Project (IOCCP).
