  There is mounting evidence that ice-sheets (and at least some glaciers) act as methane factories. Yet, the scarcity of data is still too large to quantify the role that ice masses play in global methane budgets. Here, we show how two years of high-resolution temporal data from a large (600-900 km2) land-terminating catchment of the Greenland Ice Sheet can inform on the mechanisms behind the release of methane from the ice sheet. Hydrological sensor time series of dissolved methane concentrations (CH4(aq)) suggest that emissions are tightly linked with the melting behaviours (drainage system) of the ice sheet, with pulses in CH4(aq) coinciding with distinct hydrological drainage events. Stable-isotope analyses of the CH4(aq) and microbial composition (16S rRNA) of meltwater runoff reveal a microbial origin for methane, probably from a mixture of inorganic and ancient organic carbon buried beneath the ice. Results also indicate the presence of active microbial oxidisers in glacial runoff but we consider the efficacy of this methane oxidation buffer to be limited, with estimates that the bulk (> 80%) of the methane exported from beneath the ice to be released to the atmosphere within a few kilometres of the ice margin. However, upscaling measurements into a meaningful atmospheric flux remains challenging but future work in Greenland and Norway intends to address some of these challenges
