Ice age wetland biogeochemistry: The influence of carbon dioxide starvation on wetland methane emissions
… show that the atmospheric concentration of methane (CH<sub>4</sub>) during the Last Glacial Maximum (LGM) was 40-50% lower than during the preindustrial Holocene. To understand this natural variation it is important to know how the sources and sinks of CH<sub>4</sub> change over time. …

QUANTIFYING EFFECTS OF SEASONAL INUNDATION ON METHANE FLUXES FROM FORESTED FRESHWATER WETLANDS
Developing effective strategies for reducing methane and other greenhouse gas emissions requires a quantitative understanding of their global sources and sinks. Decomposition of organic matter in wet soils is one of the largest sources of methane to the atmosphere, but it is a highly variable …

Quantifying biophysical and biogeochemical influence on northern high latitudes greenhouse gases dynamics
… processes: (1) Carbon Dioxide (CO2), (2) Methane (CH4) and (3) Nitrous Oxide (N2O). In Chapter 1, I provided a brief introduction of the overall objectives and content of this dissertation. The importance of representing (1) vertical heterogeneity of soil column, (2) CH4 transport pathways …
