Method: CALM network sites employ three primary methods of thaw depth measurement listed below and indicated by font color and letter code under the "method" column.        
  1) (P) Sites in red font use spatially-oriented mechanical probing at regular intervals across a grid and/or transect(s).                                                                    
  Just a number in this column referrs to the length of a transect or size of a grid in meters.                                                                      
  2) (TT) Sites in blue font are use thaw-tube measurements.                                                                          
  3) (T/B#) Sites in black font infer thaw depth from ground temperature measurements. "B" indicates a borehole and the following number is the depth in meters.                                                            
  Geophysical sounding methods (G) are also employed at some Antarctic sites.                                                                        
  *For detailed explanations of measurement procedures please see the methodology page on this website.                                                                    
                                                                               
Site Average Annual End of Season Thaw Depth: Thaw depths collected at the end of the thawing season are reported in centimeters.                                                               
  For spatially oriented observations the average of all sampling points are listed in the summary table.                                                                     
  For point observations (e.g., thaw tubes and ground temperatures) the values are for the single measurement.                                                                   
  Missing values are noted by "-"                                                                            
                                                                               
The summary table is available for download in Microsoft Excel (XLS) format
