The eastern flank of the Santa Barbara Basin forms the northern flanks of the Channel Islands of Santa Cruz and Santa Rosa. The physiography here is comprised of a series of terraces that are well displayed in the EM300 multibeam data set. The terraces die off toward the west. The shelf break north of the Channel Islands follows the 100 m depth contour and is thus on average 20 m lower compared to the mainland shelf edge. The shelf is characterized by northwest-southeast trending elongate ridges, with a characteristic amplitude of about 5 m and a wavelength of about 2000 m. Several slides originate along the shelf edge north of Santa Rosa Island (central and western section of above figure) extending for about 2 km to the north of the shelf edge.
