High-resolution ocean and atmosphere pCO2 time-series measurements from mooring TAO125W_0N in the Equatorial Pacific Ocean (NCEI Accession 0100076)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: October 03, 2025 | Last Modified: 2025-01-23T00:00:00.000+00:00

This dataset includes chemical, meteorological, physical time series data collected from TAO125W_0N in the Equatorial Pacific Ocean from 2004-05-08 to 2024-01-22. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 in atmosphere, pCO2 in water, sea surface salinity, sea surface temperature and pH on total scale. 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 International Ocean Carbon Coordination Project (IOCCP).
