A detailed bathymetric map has been compiled for the Ceduna Terrace, off South Australia. The most striking features of the bathymetry are numerous submarine valleys, which dissect the otherwise gently sloping terrace. These are mostly broad and shallow, and form a dendritic tributary system feeding submarine canyons on the lower slope. The valleys were probably eroded by turbidity currents generated near the shelf-break during low sea-level stands. There is little evidence to suggest that they have resulted from mass movement and slumping or from subaerial erosion. Most valleys appear to have developed during the Quaternary, but some may have originated in the Tertiary.
