Episodic fluxes of methane from subarctic fens

Quantifying landscape‐level methane fluxes in subarctic Finland using a multiscale approach

Quantifying landscape-scale methane (CH4 ) fluxes from boreal and arctic regions, and determining how they are controlled, is critical for predicting the magnitude of any CH4 emission feedback to climate change. Furthermore, there remains uncertainty regarding the relative importance of small areas of strong methanogenic activity, vs. larger areas with net CH4 uptake, in controlling landscape-l...

Modeling of Microscale Variations in Methane Fluxes

Dissertation for the degree of Doctor of Technology to be presented with due permission for public examination and debate in Auditorium Abstract: The current study analyzes the different modes of variation in methane fluxes from different microsites of a boreal mire. The results emphasize the importance of microsite characteristics, water table and vegetation cover for methane fluxes. Water lev...

A synthesis of methane emissions from 71 northern, temperate, and subtropical wetlands.

Wetlands are the largest natural source of atmospheric methane. Here, we assess controls on methane flux using a database of approximately 19 000 instantaneous measurements from 71 wetland sites located across subtropical, temperate, and northern high latitude regions. Our analyses confirm general controls on wetland methane emissions from soil temperature, water table, and vegetation, but also...
