PhD studentship at the University of Bristol, UK Supervisors: Matt Rigby (School of Chemistry) and Ed Hornibrook (School of Earth Sciences) Methane is produced and released from a range of natural and human sources, and is second only to carbon dioxide in its contribution to man-made ‘global warming’. However, a great deal of uncertainty remains about the drivers of current atmospheric methane variability. Measurements of the isotopologues of methane have the potential to provide a wealth of useful information for understanding the methane cycle, because different sources emit methane with different isotopic compositions. This project will re-evaluate stable isotope signatures currently assigned to methane emission sources and sinks and, where necessary, will involve new measurements for recently identified and significant sources of methane. The re-assessed values will then be used in a new ‘inverse model’ framework for the global methane cycle. Sources will be re-evaluated using measurements of the concentration and stable isotope composition of atmospheric methane obtained from a global network of monitoring stations. Applications should be made through the School of Earth Sciences postgraduate recruitment website: http://www.bristol.ac.uk/earthsciences/courses/postgraduate/methanebudget.html/view.
