MAGT  (C) -0.2
MAGT Depth     (m) 20.0
MAGT Date/ Period 2008

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

in table

Depth of zero annual amplitude (or depth of measurement reported above)  (m) About 18-20 m

Year or 12 month interval for mean reported above See table

Range (if applicable) of mean annual ground temperature over observation period (°C)

See table

 

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

Big Almatian Lake (Bolshoe Almatinskoe Ozero), 43 04'N, 76 59'E, 2506 m a.s.l. and 8 km beyond the K0 site by road

Data for period 1932-2000: see table.

Depth:25 m
Drilling Angle:90 °
Diameter:7.6 cm
Drilling Method:core drilling
Date Drilled:01. Jan 1973
Type:38 km beyond Almaty city, last 16 km earth road (4-wheel drive vehicle)
Distance From Road:0 m
Type:laboratory building, not heated
Distance From Heat:10 m
Other Disturbance:residential construction, heated
Distance From Heat:20 m
Permafrost Thickness:>20 m
Permafrost Zone:Discontinuous
Vegetation:Site has no vegetation, but surrounding territory can be classified as tundra
Landform:Upper Pleistocene and Holocene morainic complex
Lithology:During deep excavations (up to 10 m) near the K0 site massive cryostructures, were present deeper than 4.0-5.0 m. The largest ice bodies reached 15-20 cm in size. Iciness of permafrost varies from 5 to 40%. Above 4.0-4.5 m, the grounds has a red-brown color with obvious ferrate traces. Predominant: gravel, fragments of stones and sand without soil layer.
Morphology:Site is located near the mountain pass Zhusalykezen
