Thaw depth and water table. Active layer depth (thaw depth) in centimeters from surface (A and B) and water table (C and D) depths at four of the five sites during summer and fall 2013 and 2014 (negative values indicate thaw depth and water table below the surface). PVC pipes for water table monitoring were not allowed at the Barrow CMDL site because of clean air restriction by the NOAA. Displayed are averages and SEs from the mean (BEO, ATQ, and IVO: n= 20; CMDL: n= 45; BES: n= 50).
