Objectives

  • Improve understanding and modelling of dense water overflows, ie. "cascading" as a meso-scale process
  • Extrapolate from specific observations (focused on the edge of the continental shelf) using generic models and
  • Estimate its influence on fluxes of dissolved and particulate matter between the shelf and open ocean in the bottom boundary layer.
