News and Updates:

August 2021: Monthly Carbon Updates from Eight Mile Lake, AK

We show the cumulative flux of carbon (as carbon dioxide) to the atmosphere since eddy covariance measurements at Eight Mile Lake began in May 2008.

May 2021: New NAU study measures long-term carbon loss from thawing permafrost in Alaska

New long-term data from a permafrost monitoring site in Healy, Alaska, suggest it was a net carbon source to the atmosphere at least since 2004 and, under current climate conditions as the region grows warmer, will continue to be one, potentially losing up to a fifth of all carbon stored in the active layer of soil by the end of the century.

The research in our lab focuses on:

  • the interactions between terrestrial ecosystems and global change
  • the exchange of carbon between plants, soils, and the atmosphere
  • understanding the response of terrestrial ecosystems to changes in climate and disturbance regimes
  • responses of arctic ecosystems to climate change
  • radiocarbon dating
