  • Red indicates sites where observations are collected at regular grids;
  • [__] = CALM/ITEX investigato, see list;
  • Methods: 2-4 digit numbers refer to size of grid in meters (10, 100, 1000);
  • P = single point probe or multiple points for transects;
  • TT = thaw tube;
  • T = interpolated thaw depth based on termperature profile, generally obtained by data logger at +/- 10 cm;
  • B = closest borehole, number is depth in meters;
  • tba = data being processed;
  • I = inactive;
  • Data: dash (-) = site not yet established;
  • * = no data collected from site that year;
  • # = Russian 1000-m grid in 1997 only, all other data from 100-m grids;
  • [ ] = Canadian sites with 100-m grid data;
For sites with boreholes > 2m, interpolated thaw reported in 0.1 m
