Shallow Seas Ecosystems


Shallow seas are defined as marginal or inland extensions of ocean with average depths of about 200 m. They are also called coastal or neritic waters, and described as those lying landward of 200 m depth. Their contour is known as the continental shelf, and their seaward margin is known as the continental edge, which separates shallow waters from the deep ocean. The area of shallow seas accounts for 7.5% of the oceans, 18% of the land above the sea level, and 3% of the Earth's surface.
