Conductivity Effects on Electromagentic Emissions (EME) from Ice Fracture

Abstract

Discrete electromagnetic pulses have been recorded by scouring the surface of ice samples manufactured with significantly different concentrations of NaCl. Rise and fall times are statistically distinct and the higher the conductivity, the shorter the times recorded. As all other conditions were constant, it is concluded that EME signals are conductivity dependent. This supports the charge separation mechanism postulated for EME generation in rock and ice.
