Borehole and instrumentation is funded by the National Science Foundation under grant no: ARC-0612533: Recent and future permafrost variability, retreat and degradation in Greenland and Alaska: An integrated approach.

Primary project partners:

Vladimir Romanovsky, Permafrost Laboratory, Geophysical Institute, University of Alaska Fairbanks, Alaska, USA

Niels Foged, Department of Civil Engineering, Technical University of Denmark, Building 204, DK-2800 Kgs. Lyngby, Denmark

Keld Hornbech Svendsen, Asiaq, Qatserisut 8, P.O.Box 1003, 3900 Nuuk, Greenland

Jens Hesselbjerg Christensen, Danish Meteorological Institute, Lyngbyvej 100, 2100 København Ø, Denmark

Disturbances:  

Borehole is located 25 m from lake shore and 45-50 m from small stream and thermokarst ponds.

In the summer of 2009, a heated drinkingwater distribution pipe was constructed and buried approximately 20 m from borehole site. Dog sledding and snow machine trails pass close by borehole site.

MEAN ANNUAL GROUND TEMPERATURE AT OR NEAR DEPTH OF ZERO ANNUAL AMPLITUDE (°C) – report  value for most recent year or 12 month interval
