Figure F13. A. Line drawing of deep-tow boomer profile of part of the outer continental shelf off Anvers Island (Vanneste and Larter, 1995). B. Expanded profile showing the seaward frontal slope of a young till body and reflections from underlying bodies. Note the scale of the frontal slope, the slope-parallel internal reflectors (arrowed), and the roughness of the upper surface of the till away from the slope (a result of iceberg plowing).
