Ross Ice Shelf paper published

Our paper on the Ross Ice Shelf has just been published in the Geophysical Journal International. We analyzed data from a short-period seismic array using beamforming. The observed dispersion waves could be inverted for the velocity profile of the firn, estimating pore-close off depth and firn-air content thickness. Inversion of Rayleigh and Love wave dispersion curves led to different S-wave velocity profiles. We interpret this as an apparent anisotropy due to fine layers of varying density with the firn. Forward modeling of Rayleigh wave dispersion curves using representative firn, ice, water and sediment structures indicates that Rayleigh waves are observed when wavelengths are long enough to span the distance from the ice shelf surface to the seafloor.
