1999 Data from this  site will be downloaded in Dec 1999 by R Paetzold.

This site was established, ostensibly as a short term site,  as part of another programme, but it is hoped to maintain this as a long term  permafrost monitoring site.


MAGT (C) -17,9
MAGT_DEPTH (m) 1,2

PERMAFROST THICKNESS (if known, m)Not known but likely to be several hundred meters 


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]

PERMAFROST TEMPERATURE (and range in temperature over observation period if available) AND DEPTH AT ZERO AMPLITUDE (°C, m): Ice-cemented  at 68 cm but may not be permafrost. Table detailed data  from first year of observations not yet available.


NAME AND LOCATION OF CLOSEST CLIMATE STATION (latitude, longitude, and distance from borehole, km);  McMurdo Station         

Depth:1.2 m
Drilling Angle:90 °
Drilling Method:Excavation plus core drilling
Date Drilled:01. Jan 1999
Type:Anthropogenic: Area is part of an old US campsite, subsequently trashed with some local ground disturbance; the monitoring site is considered not to have been disturbed
Slope:4 °
Aspect:90 °
Permafrost Zone:Unknown
Vegetation:Antarctic Cold Desert, no vegetation observed at the site but small moss patches near ephemeral streams
Landform:The landform is a last glaciation retreat surface forming a narrow coastal plain; the till mantle is patchy and generally thin with scattered outcrops of local bedrock, marble, granodiorite, gneiss and dolerite; weathering evidence suggests that the landform is pre-Quaternary having been over run by ice advances on previous occasions; postglacial; site modification is unlikely.
Lithology:Patchy till cover over granodiorite/gneiss bedrock; ice content in upper permafrost varies from around 30-140%.
Morphology:Coastal Till plain. Local relief (m) A generally smooth surface with broad surface undulation to local rock outcrop about 15 m above site.
Description:This site is one of three established in January 1999 in the McMurdo Sound/Dry Valley region of Antarctica. The equipment installed included soil temperature sensors, humidity sensors and a 1.2 m temperature cable. Above ground measurements include solar radiation, air temperature, wind speed and direction. The site is currently not set up to automatically transmit data which will need to be downloaded annually. Instrumentation was provided by USDA (John Kimble and Ron Paetzold). Because of the way in which Antarctic programmes are set up and funded, secure and long term arrangements need to be put in place to ensure that data from sites such as this can continue to be gathered for effective permafrost monitoring.
