  abstract = {{S}ome regions of the {G}reenland ice sheet, where snow accumulation and melt rates are high, currently retain substantial volumes of liquid water within the firn pore space throughout the year. {T}hese firn aquifers, found between similar to 10 and 30 m below the snow surface, may significantly affect sea level rise by storing or draining surface meltwater. {T}he hydraulic gradient and the hydraulic conductivity control flow of meltwater through the firn. {H}ere we describe the hydraulic conductivity of the firn aquifer estimated from slug tests and aquifer tests at six sites located upstream of {H}elheim {G}lacier in southeastern {G}reenland. {W}e conducted slug tests using a novel instrument, a piezometer with a heated tip that melts itself into the ice sheet. {H}ydraulic conductivity ranges between 2.5 x 10(-5) and 1.1 x 10(-3) m/s. {T}he geometric mean of hydraulic conductivity of the aquifer is 2.7 x 10(-4) m/s with a geometric standard deviation of 1.4 from both depth specific slug tests (analyzed using the {H}vorslev method) and aquifer tests during the recovery period. {H}ydraulic conductivity is relatively consistent between boreholes and only decreases slightly with depth. {T}he hydraulic conductivity of the firn aquifer is crucial for determining flow rates and patterns within the aquifer, which inform hydrologic models of the aquifer, its relation to the broader glacial hydrologic system, and its effect on sea level rise.},
