The
permafrost monitoring stations consist of a small borehole (2 inches in
diameter and up to 5 m deep) that is drilled near each school. The borehole is
then lined with plastic pipe and thermistor
temperature sensors are installed at various depths. A small
battery-operated data logger (HOBO) is installed to monitor ground temperatures
at various depths in the hole. “Frost tubes” (clear plastic tubes filled with

Permafrost
monitoring stations have been installed at several hundred schools in
