MSc Thesis: Methane hotspots from a drained peatland under dairy grazing
Supervisor: Dave Campbell
Jacob’s MSc research aims to determine the magnitude of methane emissions from a drained peatland under dairy grazing and where and when do these emissions occur throughout the year. In particular, Jacob aims to identify methane emission hotspots as there is likely to be a high degree of temporal and spatial variability in the methane flux linked to the location and hydrology of drainage ditches. Flux data are being collected using soil chambers to identify methane emission hotspots and at the paddock scale an eddy covariance flux tower coupled to a continuous wave – quantum cascade laser that is used to measure net methane flux from the peat system. The results of this research will be useful for evaluating the full greenhouse gas impacts of farming drained peat and for informing future drainage management practices.
