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 Zhemchug Canyon is located in the middle of the Bering Sea, between Siberia and Alaska. It has a vertical relief of 8,530 feet or 2,600 meters dropping from the shallow shelf of the Bering Sea to the depths of the Aleutian Basin [1] and a length of 99 miles (160 kilometers).
San Antonio Canyon (Spanish: Cañón de San Antonio) is a submarine canyon located offshore San Antonio, Valparaíso Region, Chile. [1] The canyon crosses almost the whole continental shelf . [ 1 ] It has a slope of 2° from its upper parts near the coast to 80 km offshore, then slope increases to a mean of 6.3°. [ 2 ]
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 ...
Scripps Canyon was the site of the SEALAB II project in 1965, where divers dwelled in a submersible habitat at 205 ft (62 m) for 15 days at a time. [4] [5] [6] The canyon was a site of physical oceanography research in the 1970s and 1980s to look at water-sediment interactions such as turbidity currents, canyon erosion, and sediment ...
The Delgada Submarine Canyon is an underwater submarine canyon located off the King Range in Northern California. A million cubic meters of sediment fall into this canyon and another canyon each year. One end is near the coastline, close to Shelter Cove, part of the Lost Coast of California. [1] The Delgada deep-sea fan is located at the mouth ...
The connection through the Congo submarine canyon allowed the direct transfer of terrestrial materials to the abyssal zone of the fan system. [6] Unlike other rivers that empty into the sea, the Congo River is not building a delta because essentially all of its sediments are carried by turbidity currents via the submarine canyon to the fan.
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]
