Deep-sea canyons are steep-sided valleys cut into the seafloor of the continental slope, sometimes extending well onto the continental shelf. Varying in size, shape, and complexity, these canyons are fascinating under-sea geological features. Deep-sea canyons are also biologically important, creating habitat for deep-sea animals, providing shelter and hard surfaces on which to attach and diverting ocean currents to bring food to the deep. Learn more about the ocean processes that create deep-sea canyons and life that calls them home.
