Submarine canyon, any of a class of narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans. Submarine canyons originate either within continental slopes or on a continental shelf. They are rare on continental margins that have extremely steep continental.
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.

Submarine canyons are deep, large-scale incisions that occur on the continental shelf and slope of all ocean margins. These landforms serve as preferential particle-transport conduits that connect the coastal zone with the deep-sea. Canyons have been studied for decades and are among the most iconic submarine geomorphic features.
Jul 9, 2024 · The scientific name is submarine canyons, which are large cliffs and deep ravines kilometres underwater. A first-of-its-kind survey has now proved the canyons are a hotbed for marine species, stunning experts. "When we poked our nose into these deep submarine canyons, it was quite incredible.
Submarine canyons are major geologic features of continental margins that link the upper continental shelf to the abyssal plain. Results of the most recent surveys estimate approximately 9,000 canyons worldwide. Even with increased research activities in recent years, most canyons remain poorly known.
Mar 8, 2023 · Acting as a link between the continental shelf and the abyssal plain, canyons are structures that cut into the slope: they are the product of so-called "turbidity currents," or submarine currents that transport suspended solid material.
Feb 15, 2021 · Submarine canyons are similar to river gorges carved in mountainous regions on land, however they tend to be both much larger and deeper. Characteristics of submarine canyons include:
Submarine canyons are deep and intricate underwater valleys. Millions of years ago, canyons were eroded into the ocean floor along continental shelves by geological processes, like movement of tectonic plates or erosion by ancient currents.
Apr 1, 2017 · Submarine canyons are conduits delivering vast amounts of sediment, nutrients, and pollutants to deep-sea submarine fans, the largest accumulations of sediment in the world.
Submarine canyons are found throughout the world, representing complex seafloor features that link the upper continental shelf to the abyssal plain. They punctuate the margin by incising the shelf, creating scenic seascapes reminiscent of their terrestrial counterparts.
