Numerical simulations and laboratory experiments confirm my initial research hypothesis stating that dense‐water cascading down a submarine canyon induces localized upwelling of deeper water onto the shelf. This process, not described before, is associated with internal deformation radii inherent in the cascading process being less the canyon width and geostrophic adjustment of a density front that establishes along the canyon axis. Since submarine canyons are common to continental margins, this paper has identified a key process triggering the renewal of shelf waters at high latitudes.
