High-resolution ocean and atmosphere pCO2 time-series measurements from mooring GAKOA_149W_60N in the Gulf of Alaska (NCEI Accession 0116714)

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 15, 2026 at 12:00 AM
This dataset includes chemical, meteorological, physical and time series data collected from Mooring GAKOA_149W_60N in the Gulf of Alaska from 2011-05-19 to 2025-03-05. 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 UNESCO International Ocean Carbon Coordination Project (IOCCP).
