Abstract	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 Inuvik. Peak potentials of up to 1350 mV were measured on electrodes located on the advancing freezing front at Illisarvik. At Inuvik, maximum freezing potentials of up to 700 mV were measured as the active layer froze in winter. There was also evidence of downward water migration and freezing as the ground started to thaw at the surface in spring.
