Group: Summary

   Thaw depths and water depths were monitored at 1 m to 2 m intervals along a 
   255-m transect across an area of discontinuous and degrading permafrost on the 
   Tanana Flats south of Fairbanks, Alaska. Measurements were taken once a year 
   in late August from 1995 to 2002 to show effects of winter snow depths, 
   climate warming, and vegetation and wetland creation-surface subsidence. Data 
   are in a single tab-delimited ASCII text file, available via FTP.
