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 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.
8 mar 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.
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.
Submarine canyons are large geomorphological features that incise continental shelves and slopes around the world. They are often suggested to be biodiversity and biomass hotspots, although there is no consensus about this in the literature.
Canada has many submarine canyons along it’s coasts, with at least 13 canyons found in Atlantic waters and nine in Pacific waters. Submarine canyons are home to a number of deep-sea species like thorny skates, redfish, and endangered species like the northern bottlenose whale.
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.
