TAO 0° 170°W Buoy

taobuoy_pmel

The Tropical Atmosphere Ocean (TAO) moorings are supported by NOAA PMEL and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). These moorings are located across the equatorial Pacific, where changes in carbon dioxide (CO2) concentrations are subjected to major climate variations, such as El Niño or La Niña. The NOAA PMEL Carbon Program has mounted CO2 sensors on a number of these moored buoys to monitor the changes in carbon dioxide. More information about the TAO Moorings are available on the TAO website.

The entire CO2 time series for the TAO 0° 170°W Buoy is shown below. For closer inspection of the dataset, simply slide the striped black markers on the bottom right and left of the graph to narrow the time range. The CO2 for the air and sea water are in molar fractions (µmol/mol), meaning it is the molar amount that CO2 accounts for out of the total substance.
