Cascading-driven upwelling in submarine canyons at high latitudes.

Summary

Numerical simulations and laboratory experiments confirm my initial research hypothesis stating that dense water cascading down a submarine canyon induces localised upwelling of deeper water onto the shelf. This process, not described before, is associated with internal deformation radii inherent with 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.
