Feasibility of Determining Subsurface Permafrost Structure Using Acoustic Pulse Echo Techniques.
Abstract
The results of controlled laboratory experiments on the acoustic properties of representative samples of permafrost are reported and the data compared with theoretical predictions. Measurements of velocity, attenuation and reflectivity were performed and evaluated with respect to the feasibility of using pulse echo techniques to analyze near (<50 ft) subsurface permafrost structure. Although acoustic pulse echo techniques appear feasible, further laboratory experiments, as well as field tests, to measure the acoustic properties of permafrost in situ, are recommended. (Author)
