Modeling

We have created a new process-model of methane uptake by soil, based on a compilation of field measurements showed significant differences in methanotrophy rates in different ecosystems. Our model incorporates different microbial oxidation rate constants for different ecosystems and we find that the methanotrophy rates we derive are much more …

Based on measurements compiled from the past couple of decades on the wetland d13C-CH4 isotopic source signatures from different wetland ecosystems, we have produced a spatially-resolved gridded map. This map distinguishes bogs and fens in the northern high-latitudes, which have dramatically different signatures due to the fundamental differences in hydrology, …
