All nautical charts give some information about the ocean floor, depths and bottom composition mainly, but they require some interpretation and are of limited value for picking dive sites. The state of CA has a side-scan sonar survey of certain areas. Also if it's small scale (large area) pictures you want, the National Geographic Society has awesome representations of ocean basins for sale.
