Seismic and radar investigations of Fourcade Glacier on King George Island, Antarctica
2010
Polar Research
To determine P-and S-wave velocities, elastic properties and subglacial topography of the polythermal Fourcade Glacier, surface seismic and radar surveys were conducted along a 470-m profile in November 2006. P-and S-wave velocity structures were determined by travel-time tomography and inversion of Rayleigh wave dispersion curves, respectively. The average P-and S-wave velocities of ice are 3466 and 1839 m s -1 , respectively. Radar velocities were obtained by migration velocity analysis of
