The  borehole was drilled into the permafrost during the spring of 2006 and a temperature sensor chain installed in August 2006, with 24 temperature sensors down to a depth of 26.75m. The temperature sensor chain was inserted into a close-fitting PVC tube to allow reinstallation and recalibration of sensors. The absolute accuracy of the temperature sensors is ±0.005 °C across the range from −40 °C to 35 °C (RBR Ltd.). A second 5 cm (outside diameter) PVC tube was inserted into the borehole to permit additional (geophysical) measurements to be made in the future. The remaining air space in the borehole was backfilled with dry sand.

Continuous measurements since 24.08.2006
