See caption below; northeast Channel Islands colored shaded-relief multibeam bathymetry perspective view 6

Perspective view of the Northeastern Channel Islands multibeam bathymetry looking north towards Ventura and Port Hueneme at the eastern end of the Santa Barbara Channel (arrow 6 on location map). In the center of the channel in about 230 m water depth are a field of bedform-like features. 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). The smaller features at B-B' have lower relief (1 - 4 m), but 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.
