Group: Summary

   This study investigates the thickness of the active  layer of palsas in 
   northernmost Finland and temporal, local, and  regional differences in the 
   thawing of palsas there.  (Seppala  1983).  Probes of frost depth were made 
   over a 9-year period, a  total of 185 measurements in 17 palsa bogs at sites 
   ranging from  50 - 490 m in altitude. Thermal gradients were also measured ;   
   weather observations were taken at two sites.
