Group: Summary

   These data have been collected from an Arctic desert site (latitude 78o57'29N, 
   longitude 12o27'42E), Broeggerhalvoya in  western Spitsbergen, 10 km NW from 
   Ny Alesund, 45 m above sea  level, 2 km from the shore. This is a low relief 
   tip of a bedrock  peninsula covered with several meters of glacial drift and 
   reworked raised beach ridges. The measurements are obtained in the site of 
   well developed patterned ground, sorted polygons, where the influence of 
   plants, including thermal insulation and transpiration, is negligible. The 
   1985-1986 period was average. Mean annual air temperature was -6.6 C, 0.4 C 
   colder than the long-term (1975-1990) mean, but well within the mean 
   variability. Mean winter air temperature is relatively warm (mean of coldest 
   month, February, is -14.6 C). Annual precipitation was 17 % greater than the 
   ong-term mean (372 mm); however, the number of rain-on-snow events was less 
   (3) than average (5.5). Overall, the reference period is close to long-term 
   averages.    
A program of automated soil temperature recordings was initiated 
   in the summer of 1984, at a patterned ground field site Thermistors were 
   placed approximately 0.1 m apart in an epoxy-filled PVC rod (18 mm outside 
   diameter), buried in the center of a fine-grained domain of a sorted circle, 
   down to 1.14 m below the ground surface. The data presented here covers 
   7/1/85-7/1/86, once a day (6 am), at two levels (0.0 m, 1.145 m below 
   surface). The resolution of the thermistors is 0.004 C, and the accuracy is 
   estimated to be 0.02 C near 0 C. Missing data accounts for less than 7 %. The 
   gaps are filled with simple average of the beginning and end of the gap 
   values. For a detailed description of the field site and data analysis see 
   Putkonen (1997) and Hallet and Prestrud (1986).  These data are presented on 
   the CAPS Version 1.0 CD-ROM, June 1998.
