Antarctic ice sheet thickness estimation using the H/V spectral ratio method with single-station seismic ambient noise

Abstract

Abstract. The horizontal-to-vertical spectral ratio (H/V) method implemented at single stations using seismic 11 ambient noise waveforms is a fast, noninvasive, efficient method to investigate the subsurface velocity 12 structures of the shallow crust. In this study, we report on a successful application of the H/V method to estimate 26of seismic ambient noise records can be shortened to 1-2 hours for reliable ice sheet thickness estimation using 27 the H/V method. This study extends the application fields of the H/V method and provides a complementary and 28 independent way to measure ice sheet thickness in Antarctica.
