Permafrost present but thickness not known.

 

 

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

Deepest sensor at 6.75 m, MAGT 2007-08-01 to 2008-08-01: -1.63 °C

Maximum minus minimum temperature at 6.75 m, 2007-08-01 to 2008-08-01:  0.66 °C

NB: Month of August 2007 missing from dataset due to data logger mal function. The stated mean annual temperatures should therefore be considered approximate, and true temperature would be higher.

 

AIR TEMPERATURE AND SNOW COVER THICKNESS/DENSITY MEASUREMENTS AT THE BOREHOLE SITE (indicate frequency of observations):

Air temperature: Yes [X] No [ ]    Snow thickness: Yes[ ] No[X]   Density: Yes [ ] No[X]

 

NAME AND LOCATION OF CLOSEST CLIMATE STATION (latitude, longitude, and distance from borehole, km) – provide (if available) mean monthly air temperature and snow depth of reporting interval for mean annual ground temperature –
