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