This dataset contains time-series measurements of simultaneous borehole water and drill water temperature, measured in an instrumented drill stem during hot water drilling of boreholes in western Greenland. Ice deformation is concentrated at depth, and the processes dictating ice sheet sliding depend on the physical condition of the ice sheet bed, but the remote nature of deep ice conditions severely limits observation. This motivates novel measurements to maximize the information content in boreholes which directly access the ice sheet bed but are logistically and technically challenging. Time series of borehole water temperatures provide an additional test of the abruptness of the basal boundary (Harper et al., 2017), and thermal dissipation is also used as a measure to constrain resident water volume at the ice sheet bed (Meierbachtol et al., 2016).
