Revealing drivers of nitrous oxide (N2O) fluxes in a thawing sub-Arctic permafrost peatland
… has increasingly focused on nutrient-rich Arctic soils. However, most Arctic soils are nutrient-poor, and the mechanisms controlling their typically low N₂O fluxes remain poorly understood. This thesis advances understanding of low N₂O fluxes in a nutrient-poor, highly heterogeneous Arctic …

Biogeochemical investigations of methane-rich groundwaters in high Arctic glacial catchments
Permafrost and glaciers in the high Arctic form a near-impermeable ‘cryospheric cap’ that traps a potentially large reservoir of sub-surface methane and prevents it from reaching the atmosphere. The vulnerability of the cryosphere to climate warming is making releases of this methane possible, but …
