Figure
11. Graph showing the variations of four grain size components with depth. The lower beach
face (roughly 0-25 m depth) is characterized by the fine sand fraction exceeding 40%. The
inner shelf (roughly 25-55 m depth) is characterized by the very-fine sand fraction mostly
exceeding 40%. The middle shelf (roughly >55 m) is characterized by the silt and clay
content exceeding 25%. Click on the figure to view a larger image. Sample locations
