A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km (3 mi), from canyon floor to canyon rim, as with the Great Bahama Canyon.

The undersea cliff is incised by more than 500 canyons, while landslide occurrence has been inferred from sediment samples collected from the base of the escarpment.The 2012 research on the escarpment closest to Sicily identified 70 submarine landslides as well as black coral reefs, while a 2014 survey focused further south but still on the northern part of the escarpment, especially on the ...
Zhemchug Canyon (from the Russian жемчуг, "pearl") is an underwater canyon located in the Bering Sea between the Siberian and Alaskan coastlines. It is the deepest submarine canyon in the world with a vertical relief of 8,530 feet (2,600 meters) and a length of 99 miles (160 kilometers).

The continental slope often exhibits features called submarine canyons. [4] Submarine canyons often cut into the continental shelves deeply, with near vertical sides, and continue to cut the morphology to the abyssal plain. [5] These canyons are often V-shaped, and can sometime enlarge onto the continental shelf.
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 .
Monterey Canyon begins at Moss Landing, California, which is situated along the middle of the coast of Monterey Bay, and extends horizontally 95 mi (153 km) under the Pacific Ocean where it terminates at the Monterey Canyon submarine fan, reaching depths of up to 3,600 m (11,800 ft) below surface level at its downstream mouth. It is a part of ...
