John is a final year PhD researcher at the Environmental Research Institute, based within the institute's Peatland research theme. His research is looking at the biogeochemical processing of carbon in peatland pools and seeks to both quantify carbon dioxide and methane fluxes from freshwater pools in the blanket bogs of the Flow Country in Northern Scotland and investigate the dominant processes controlling these fluxes. Aims of the project are to study spatial and temporal variability of fluxes, and to assess the contribution of peatland pools to the carbon balance of the wider peatland ecosystem. This work will improve understanding of a critical component of carbon cycling in northern peatlands.
