Field measurements of electrical freezing potentials in permafrost areas
Electrical potentials developed during freezing of natural soils have been measured in two permafrost areas: one in a saturated sand in a drained lake (Illisarvik) on Richards Island where permafrost was aggrading downward 5.65 m below ground; the other, in a mud hummock in the active layer at Inuvi...
