Geophysical Data Collection

• Air temperature.
• Snow depth, ultrasonic sensor.
• Solar panel.
• Lighting rod.
• High density soil temperature array (MRC) from the surface till 1 meter depth.
• Three soil moisture probes with temperature sensors at 0.05, 0.15, 0.3 meter.
• Where possible deep boreholes to monitor long term changes in permafrost temperature.
• Datalogger
• Operation on an houly time step for surface processes.
• Deep boreholes measured annually.

Other methods:

• Soil temperature measurements using HOBO loggers at a variety of depths.
• Soil liquid water content using DC resistivity.

• Ground penetrating radar (GPR).
• Borehole logs and samples.
• Surface features, thermokarst, ice wedge polygons, non-sorted circles, earth mounds, palsas, pingos, tufurs.

• Soil pits in summer and frozen soil cores in winter.

• Frost heave meters
