Hot water drilling and mass-balance measurements were made on the Inland Ice at Pakitsoq north-east of Jakobshavn. Two arrays of moderate and shallow-depth thermistor strings have been installed in the ice to map the englacial temperature from the ice margin to the equilibrium line. Water fluctuations were observed in a drill hole connecting to the ice bed. The measurements indicate a high subglacial water pressure dose to the ice overburden pressure.
