Scientists from NOAA’s Pacific Marine Environmental Laboratory, the University of Alaska and the Alaska Ocean Observing System are teaming up this summer and early fall to use new unmanned tools to study how melting glaciers in Alaska’s Prince William Sound may be intensifying ocean acidification in the sound and on the Gulf of Alaska continental shelf.
New NOAA research has revealed unprecedented changes in ocean carbon dioxide in the tropical Pacific Ocean over the last 14 years, influencing the role the oceans play in current and projected global warming and ocean acidification. Natural variability has dominated patterns in ocean CO2 in this region, but observations now show human activity contributes to increasing CO2 levels.
On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958.
Earth’s oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study by University of Colorado and NOAA scientists published today in the journal Nature.
The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, has reached a new milestone this spring, according to NOAA measurements.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
