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.

Map of Bering Canyon and four other submarine canyons in the Bering Sea. Bering Canyon, in the Bering Sea near the Aleutian Islands, Alaska, the United States; Kaikōura Canyon, off the coast of the Kaikōura Peninsula, New Zealand; La Jolla Canyon, off the coast of La Jolla, California; Monterey Canyon, off the coast of central California, 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).
It is the largest known ocean canyon off the East Coast of the United States, and one of the largest submarine canyons in the world. The canyon is located near the 100 m (330 ft) isobath on the continental shelf and is 2.2 km (1.4 mi) deep at the base of the continental slope. Over an 80 km (50 mi) distance, the average slope of the canyon ...
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.
It lies opposite the Quinault Reservation. [3]From the map, it is clear the Quinault River drains into the Pacific Ocean, opposite Quinault Canyon.The north of the Copalis National Wildlife Refuge is also a bit east, as are a few cities and sites, as Kalaloch, Queets, Taholah, Point Grenville (a headland), Moclips, and Pacific Beach.
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.
