Figure 6. Figure 1: Perspective view of the Northeastern Channel Islands multibeam bathymetry looking north towards the towns of Ventura and Port Hueneme at the eastern end of the Santa Barbara Channel (arrow 6 on location map). In the center of the channel under about 230 m water depth is a bedform field. The larger features at A-A' have wavelengths on the order of 50 - 125 m with heights of about 3 - 12 m (see profile A-A' below). In contrast, the features at B-B' are less high (1 - 4m), but they have longer wavelengths of 200 m (see profile B-B' below). The distance across the bottom of the image is approximately 12 km. The vertical exaggeration is 2X.
