A global report released this week on changing carbon dioxide levels in Earth’s atmosphere, oceans, and land environment draws heavily from data and observations by NOAA research scientists and their partners. For the first time, the annual assessment by the Global Carbon Project uses data obtained from autonomous instruments installed by NOAA scientists on its ships and other ships of opportunity and moorings to determine the variability of carbon dioxide in the surface ocean.
The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world's ocean area remains relatively unknown to scientists, as observations remain hindered by dangerous seas.
What’s the first thing that comes to mind when you hear the words carbon dioxide? Is it the ocean? In this day and age, it should be. The ocean absorbs about one fourth of the extra carbon dioxide in the air that is released through human activity, according to a researcher at Scripps Institution of Oceanography.
Ocean acidification is driving changes in waters vital to Alaska’s valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in Progress in Oceanography.
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.
