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.

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 ...
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 ...
The Northeast Canyons and Seamounts Marine National Monument is located within the New England and mid-Atlantic regions, 130 miles southeast of Cape Cod. [1] It comprises a total area of 4,913 square miles, [1] and protects four underwater seamounts (Bear, Mytilus, Physalia, and Retriever Seamounts) and three submarine canyons in the edge of the continental shelf (Oceanographer, Lydonia, and ...

The Nazaré Canyon off the coast of Portugal. The Nazaré Canyon is a submarine canyon just off the coast of Nazaré, portuguese Oeste region, in the eastern North Atlantic Ocean. It is the largest submarine canyon in Europe, [1] reaching depths of about 5,000 metres (16,000 ft) deep and a length of about 230 kilometres (140 mi). [2]
Scripps Canyon is a narrow submarine canyon in the Pacific Ocean, off the coast of Southern California, United States. The canyon is approximately 1 mile (1.6 km) long and joins La Jolla Canyon offshore. [1] Scripps Canyon is a popular site for scientific and recreational diving due to its vertical walls and high density of marine life.
