The crystal orientation fabric of glacier ice impacts its strength and flow. Crystal fabric is therefore an important consideration when modelling ice flow. Here, we show that shear-wave splitting (SWS) measured with glacial microseismicity can be used to invert for seismic anisotropy and ice fabric...
