Abrupt changes in crystal-orientation fabric (COF), and therefore viscosity, are observednear the base of the ice sheet throughout West Antarctica. We report on active-source seismicobservations from WAIS Divide, mid-stream and downstream on Thwaites Glacier, and the onset regionof Bindschadler Ice...
