  abstract = {{F}irn aquifers have been discovered across regions of the {G}reenland ice sheet with high snow accumulation and melt rates, but the processes and rates that sustain these aquifers have not been fully quantified or supported by field data. {A} quantitative description of the hydrology of a firn aquifer upslope from {H}elheim {G}lacier that integrates field measurements is presented to constrain melt and recharge rates and timing, temporal variations in temperature and water levels, and liquid-water residence time. {F}ield measurements include weather data, firn temperatures, water levels, geochemical tracers, and airborne radar data. {F}ield measurements show that once the firn column is temperate (0 degrees {C}), meltwater from the surface infiltrates to the water table in less than 2 days and raises the water table. {A}verage recharge is 22 cm/year (lower 95% confidence interval is 13 cm/year and upper 95% confidence interval is 33 cm/year). {M}eltwater within the recently formed aquifer, which flows laterally downslope and likely discharges into crevasses, has a mean residence time of similar to 6.5 years. {A}irborne radar data suggest that the aquifer in the study area continues to expand inland, presumably from {A}rctic warming. {T}hese comprehensive field measurements and integrated description of aquifer hydrology provide a comprehensive, quantitative framework for modeling fluid flow through firn, and understanding existing and yet undiscovered firn aquifers, and may help researchers evaluate the role of firn aquifers in climate change impacts.},
