description

The floor of a gulf is drawn as stepped depth bands. The shelf near the coast is the lightest green; each band further out is darker, down to a single deep-blue pocket at the bottom edge of the frame. The land above is one flat tone.

The steps replace a continuous gradient with a few distinct levels, so the seafloor is drawn as a set of terraces. The coastline is the most detailed edge in the image. The deepest shape is cut off by the frame and stays unresolved.
