Use of Shear Waves to Measure Poisson's Ratio in Polar Firn

Journal of Environmental and Engineering Geophysics, 2007
Abstract We conducted a seismic experiment on polar firn on Adelaide Island, Antarctica. We measured the speed of compressional and shear waves at different depths in the firn by sampling waves that return to the surface following continuous refraction.
