Ice augers and ice thick­ness gauges

Canadian Geographic - - DISCOVERY INFOGRAPHIC -

When GPR sen­sors aren’t used, builders must man­u­ally check the thick­ness of an ice road. To do this, they use an ice auger to drill a hole from the road sur­face to the wa­ter be­low. A spe­cial­ized mea­sur­ing gauge shaped like a long fish hook is then pushed into the hole and se­cured to the un­der­side of the ice. The ice thick­ness is mea­sured along the shaft of the gauge.
