NOPP: Circulation, Cross-Shelf Exchange, Sea Ice, and Marine Mammal Habitats on the Alaska Beaufort Sea Shelf

Abstract

Our long-term goal is to understand how the circulation, stratification, sea-ice dynamics, and marine mammal utilization of arctic shelves will change in response to a diminishing ice cover. We thus seek to understand better the wind-forced response of the shelf and the shelfbreak, and the cross-shelf exchange of mass, materials, and momentum. These responses will likely affect the use of arctic shelves by marine mammals. Our study is applying a variety of recently developed technologies in a synergistic manner. These include passive acoustic recorders, moored profiling temperature/salinity sensors, autonomous underwater vehicles, shore-based current mapping radars, and geophysical processing tools to determine ice displacement and deformation. An additional long-term goal is to demonstrate the applicability of these technologies and their synergistic usage to other arctic shelves.
