The PI will use the fact that the study area, the Beaufort Sea shelf and slope, is seasonally ice-free to explore the impact that a changing ice cover may have on internal wave energy levels, both through changes in the efficiency of generation, and changes in under-ice dissipation. Simulations will be tightly linked to the field data, using measured upper ocean sea-ice drift and deformation, currents and remote sensing products. In particular, the study will address the following new questions: 1) How much of the observed downward energy flux out of the ice-covered ocean reaches the continental slopes? 2) Does the measured incoming energy flux accumulate at the shelf-break, which is critical to almost all internal waves in the Arctic? 3) Is this energy accumulation sufficient to account for the implied mixing rates required to ventilate the abyssal Beaufort Sea? 4) What are the relative efficiencies and damping rates of near-inertial waves subject to bottom, under-ice, open water, and critical slope reflections?
