Record #117849:

Electromagnetic emission (EME) from ice crack formation: preliminary observations / Daniel V. Thiel.

Title: Electromagnetic emission (EME) from ice crack formation: preliminary observations / Daniel V. Thiel.
Author(s): Thiel, Daniel V.
Date: 1992.
In: Cold Regions Science and Technology. (1992.), Vol. 21(1) (1992)
Abstract: EMEs were recorded in vicinity of ice cracks created by breaking rods of ice, scouring ice surface, applying uniaxial pressure to cylindrical ice core, and using bore-hole jack in ice sheet. Observations were made from 50 Hz to 15 kHz, using two-channel audio cassette recorder and wire probes inside and outside ice. EME events correlate with acoustic emission events which arise during crack formation. This is consistent with observations made in rocks. Electromagnetic fields generated propagate within ice in form of guided wave.
