Explosion-produced seismic surface waves recorded along the Byrd Station Strain Network in West Antarctica were investigated. Amplitudes were much greater for Rayleigh waves than for Love waves. Higher modes of both wave types were registered. Group velocity dispersion analysis revealed significant lateral inhomogeneity in near-surface structure of the ice sheet throughout the study area. Velocity anisotropy was indicated at one site.
