The formation of submarine canyons is believed to occur as the result of at least two main process: 1) erosion by turbidity current erosion; and 2) slumping and mass wasting of the continental slope. While at first glance the erosion patterns of submarine canyons may appear to mimic those of river-canyons on land, several markedly different ...
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 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 .
Remnants of submarine fan facies outcrops are found as far west as the northern Channel Islands. Inland Ballena River deposits outcrop discontinuously over 16 miles (26 km) in a west-southwest trend from Whale Mountain to San Vicente Reservoir ; here, the river was up to 2 miles (3.2 km) in width through the Peninsular Ranges .
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]
The Amazon Canyon is a submarine canyon within the Amazon Fan in the Atlantic Ocean, located approximately 200 mi (322 km) from the mouth of the Amazon River, near South America. It covers an area of 2,250 km 2 (870 sq mi). [1] It was formed in the mid to late Miocene period. [1]
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.
