Characteristics of Sea Ice, Lake Ice and Permafrost Using an Impulse Radar System.

Abstract

An impulse radar system was developed to perform shallow subsurface investigations. The technique is known as Electromagnetic Subsurface Profiling (ESP) and is the electrical analog of the seismic sub-bottom profiling method used in marine geology. The radar system operates by detecting the interface between two materials having different electrical properties. For sea ice and lake ice, an electromagnetic pulse is generated near the ice surface and the reflections from the surface and the ice/water interface are displayed on a continuous strip-chart recorder. Large masses of ground ice in perma-frost have been located with the system. Theoretical considerations indicate that the system also should be able to determine the approximate volume of interstitial ice in frozen soils. (Modified author abstract)
