Research Topic

Peatland/Wetland Methane Dynamics
Clarice's research is on methane dynamics of northern wetlands, including peatlands in the discontinuous permafrost zone, with a focus biological methane oxidation. I use trace gas analysis, incubation experiments, microbial ecology, and redox chemistry measurements to investigate methane dynamics in northern peatlands.
