Deep-Sea Canyons
Deep-Sea Canyons
NOAA's Ocean Explorer
"Submarine canyons are steep-sided valleys cut into the sea floor of the continental slope, sometimes extending well onto the continental shelf. These canyons vary in size, shape, and morphological complexity; some were scoured by the flow of rivers during past low sea level periods, but most formed via other erosional processes, such as mud-slides, debris flows, and turbidity currents."
