Group: Summary

   The CALM network includes 168 active sites in both hemispheres, with 15 
   participating countries.  This network represents the only coordinated and 
   standardized program of observations using standard measurement protocols 
   designed to observe and detect decadal changes in the dynamics of seasonal 
   thawing and freezing in high-latitude soils. The Intellectual Merit of this 
   study lies in the need for long-term time series of active layer depth, ground 
   temperature, and thaw settlement measurements at the same locations and across 
   diverse terrain types and regions in order to identify scales of spatial 
   variation, establish trends, and validate models.

   The active layer thickness is measured by physical probing on grids ranging in 
   size from 100 to 1000 meters, by probing at a single point or along transects 
   or from permanently installed frost tubes and soil temperature cables. Sites 
   include several coastal to inland transects in North America, a longitudinal 
   array of sites across Eurasia, and individual sites in several mid-latitude, 
   mountainous regions. The majority of the sites are in arctic tundra regions 
   consisting of fine grained sediments. Bouldery and rocky sites in mountains 
   are being added to the network primarily in Europe as part of the EC 
   Permafrost and Climate in Europe (PACE) project. CALM is being considered as 
   the part of the Global Climate Observing System (GCOS). CALM is closely 
   affiliated with the International Permafrost Association (IPA), several IPA 
   working groups, and the International Tundra Experiment (ITEX). The current 
   protocol for observing the active layer thickness is given in the published 
   ITEX Manual and on the ITEX and IPA web sites. These activities are part of 
   the IPA Global Geocryological Database (GGD). A map on the CAPS CD-ROM 
   illustrates the locations of the 130 sites. A comprehensive metadata file for 
   all sites is available. 

   The CAPS CD-ROM contains detailed metadata and summary data. Raw data can be 
   found at the CALM web site.
