The continental shelf is a large underwater terrace which is relatively at low depth of the continental crust forming the edge of a continental land mass. Data Table. Larger animals such as whales and sea turtles can be seen in continental shelf areas as they follow migration routes. Beyond the shelf-slope break, the continental crust thins quickly, and the rise lies partly on the continental crust and partly on the oceanic crust of the deep sea.

The Federal Government administers the submerged lands, subsoil, and seabed, lying between the seaward extent of the States' jurisdiction and the seaward extent of Federal jurisdiction. Continental Shelf. Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. The shelf break (i.e. Below the slope is the continental rise, which finally merges into the deep ocean floor, the abyssal plain. The term "continental shelf" is used by geologists generally to mean that part of the continental margin which is between the shoreline and the shelf break or, where there is no noticeable slope, between the shoreline and the point where the depth of the superjacent water is approximately between 100 and 200 metres. The continental shelf includes the Malin and Hebrides Shelf Seas, Orkney and Shetland Shelf Seas, and the North Sea. The average width of a continental shelf is 65 kilometers (40 miles).
