The shelves make up less than 10% of the ocean, and a rough estimate suggests that only about 30% of the continental shelf sea floor receives enough sunlight to allow benthic photosynthesis. [36] Though the shelves are usually fertile, if anoxic conditions prevail during sedimentation, the deposits may over geologic time become sources for ...
The continental shelf of the United States is one of the largest examples of marine geology in the world, with thousands of miles of submarine land making up the various shelves of the collective. Each different shelf features different extents of continental shelves, from the long, elevated shelves of Alaska, to the short shelf of the Pacific ...
The width of continental shelves worldwide varies in the range of 0.03–1500 km. [4] The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and typically steeper closer to the coastline than it is near the shelf break.

The Ross Ice Shelf is one of many such shelves. It reaches into Antarctica from the north, and covers an area of about 520,000 km 2 (200,000 sq mi), nearly the size of France. [2][3] The ice mass is about 800 km (500 mi) wide and 970 km (600 mi) long. In some places, namely its southern areas, the ice shelf can be almost 750 m (2,450 ft) thick.
The Hudson Canyon is a submarine canyon that begins from the shallow outlet of the estuary at the mouth of the Hudson River. It extends out over 640 km (400 mi) seaward across the continental shelf finally connecting to the deep ocean basin at a depth of 3–4 km (1.9–2.5 mi) below sea level. It begins as a natural channel of several ...
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately 200 meters (660 ft) in depth. [1][2] From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals ...
