Abstract

Sidescan and 3.5kHz profiler data from the Antarctic Peninsula continental shelf (Fig. 1) show good examples of glacial flutes and iceberg furrows. The Antarctic Peninsula shelf environment is described by Larter et al. [this volume], Larter and Barker [1989] and Pudsey et al. [1994]. The sidescan sonar was a hull-mounted system, stabilised for roll, with operating frequencies of 31–33 kHz. A horizontal range of 1500m or 2500m was used in water depths of 200–700m.
