Shear-wave velocities under the Transantarctic Mountains and Terror rift from surface wave inversion
Abstract. Rayleigh wave data between 20 and 120s period recorded in the western Ross Sea region of Antarctica are in-verted using the waveform inversion technique described in Passier and Snieder [1995]. From the data we extract esti-mates of local S velocity structure beneath the Transantarc-tic Mo...
