Feasibility of Determining Subsurface Permafrost Structure Using Acoustic Pulse Echo Techniques.

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...
