    A team of researchers that included several INSTAAR scientists received the prestigious Kirk Bryan Award from the Quaternary Geology & Geomorphology Division of the Geological Society of America (GSA). The prestigious award honors the authors of a recent paper that advances the science of geomorphology.

    The Los Angeles Basin is often thought of as a dry, heavily developed landscape. But a new study in PNAS led by NOAA and the ºù«ÍÞÊÓƵ shows that the manicured lawns, emerald golf courses, and trees of America’s second-largest city play a surprisingly large role in its carbon footprint.

    A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.
  • Chad Wolak prepares NOAA air samples for carbon-14 measurement.
    Researchers from NOAA and the University of Colorado have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon scientists have relied on for decades to date archaeological sites. In a paper published in Proceedings of the National Academy of Sciences, they report the first-ever national scale estimate of fossil-fuel derived carbon dioxide (CO2) emissions obtained by observing CO2 and its naturally occurring radioisotope, carbon-14, from air samples collected by NOAA’s Global Greenhouse Gas Reference Network.
