Collaborative Research: Geophysical Evaluation Of Biogenic Gasses In Peatlands, Andrew S. Reeve
Collaborative Research: Geophysical Evaluation Of Biogenic Gasses In Peatlands, Andrew S. Reeve
University of Maine Office of Research Administration: Grant Reports
Biogenic gas emission from northern peatlands, by wicking from vascular plants and by episodic ebullition events, accounts for approximately 7% of the global annual emission of methane to the atmosphere. This proposal involves experiments to apply ground penetrating radar (GPR) for (1) estimating the amount of biogenic gas stored in peatlands, (2) determining the spatial distribution of biogenic gas within the peat, and (3) monitoring biogenic gas release to the atmosphere. Data from a large northern peatland in Maine (EAR-0242353) show that (1) higher CH4 and CO2 concentrations correlate with high velocity/high attenuation zones in cross-borehole GPR data as well …
