Methane Cycling in Northern Peatlands

 

Peatlands are responsible for significant sequestration and production of greenhouse gases, and their impact on/response to climate change may have severe global impact.  The focus of this project is to expand upon existing peatland carbon cycling models and improve our understanding of peatland gas dynamics.  To study these mechanisms, a suite of hydrological and hydrogeophysical monitoring tools are being used to record data across multiple spatial scales at a remote field site in central Maine.

From our field data, we hope to:

[1] Quantify vertical variation in free phase gas (FPG) content at three field locations,

[2] Establish hydraulic forcing mechanisms governing FPG release,

[3] Link spatial variation in FPG content to subsurface heterogeneity,

[4] Quantify “deep” versus “shallow” FPG production in peat.
