Investigating Subglacial Water-filled Cavities by Spectral Analysis of Ambient Seismic Noise: Results on the Polythermal Tête-Rousse Glacier (Mont Blanc, France)

Résumé

• Spectral analysis from ambient seismic noise is complementary to other geophysical methods for investigating glaciers at depth • Results suggest that the vertical-to-horizontal spectral ratio (VHSR) is a reliable proxy to locate subglacial cavities • Experimental results were confirmed using a simplified numerical model
