FIG. 47b. Side-scan sonograph of subtidal sand waves with superimposed sand waves, San Francisco Bay, California. The main sand waves are 3-4 m in height and are migrating from left to right. The migration direction of the superimposed sand waves varies with location on the main sand waves; on the dominant lee slopes of the main sand waves, the divergence is roughly 90 degrees. The field of view is 75 m from top to bottom and 600 m from left to right.
