Fig. 1. Schematic diagram showing slope and basinal deep-marine sedimentary environments occurring at water depths deeper than 200 m (shelf-slope break).In general, shallow-marine (shelf) environments are characterized by tides and waves, whereas deep-marine (canyon, slope, and basin) environments arecharacterized by mass flows (i.e. slides, slumps, grain flows, and debris flows), various bottom currents, and pelagic/hemipelagic deposition. Turbidity currentsare rare in submarine canyons, but common in basinal settings. Submarine canyons are unique because the shelf-slope break does not control processes withinthe canyon; more importantly, both tidal currents and mass flows operate within canyons (see text for details). Note up- and down-tidal bottom currents insubmarine canyons (opposing red arrows). Along-slope movement of contour-following bottom currents and circular motion of wind-driven bottom currentsare important processes outside of the canyon.
