Compressional and EM Wave Velocity Anisotropy in a Temperate Glacier Due to Basal Crevasses , and Implications for Water Content Estimation


We have conducted a series of experiments designed to investigate elastic and electromagnetic (EM) velocity anisotropy associated with a preferentially aligned fracture system on a temperate valley glacier in south-central Alaska, USA. Measurements include a three-dimensional compressional wave (P-wave) seismic reflection survey conducted over a 300m 300m… (More)
