Measuring winter carbon flux on the Alaskan tundra
Channel: AGU
Date: 11/02/2016

Ecosystem ecologist Elizabeth Webb describes her team’s work measuring carbon dioxide flux in the Alaskan permafrost during the winters of 2008-2009 through 2012-2013. They found that warming increases the amount of carbon lost by 9-36% over the winter.  When compared with the summertime carbon flux at the same site, their data show that carbon released to the atmosphere during the winter outweighs summertime carbon gains, resulting in a net loss of carbon to the atmosphere.
