We use seismic refraction data to investigate the firn structure across a suture zone on the AmeryIce Shelf, East Antarctica, and the possible role of glacier dynamics in firn evolution. In the downstreamdirection, the data reveal decreasing compressional-wave velocities and increasing penetrationde...
