Abstract
The Bering and Chukchi/Beaufort shelf-breaks form the beginning and end of the dramatic sea-level and wind-forced flow of Pacific Ocean water across the Bering and Chukchi continental shelves between the Pacific and Arctic Oceans. Recent model results suggest that the on-shelf flow in the Bering is distributed along the shelf-break, wind-dependant, focused by Zhemchug and Bering canyons and modified by shelf-break eddies. Similarly, the off-shelf flow in the Chukchi/Beaufort is mediated by canyons, shelf-break jets, eddies, and wind forcing. In the Chukchi, flow is channeled through Barrow and Herald canyons to the shelf-break, where across-slope flow in Ekman boundary layers and instabilities result in the exchange of water and properties across the slope. In addition, dense shelf-water, created from brine rejection during ice formation in coastal polynyas, has been observed to flow downslope through Barrow Canyon. Along the Beaufort shelf, the shelf-break current is unstable, shedding eddies that populate the deep Beaufort basin. Upwelling favorable winds in summer have been observed to modify the structure of the shelf-break current and drive exchange across the Chukchi and Beaufort slopes. Most of our understanding of shelf-break flow in Bering and Chukchi Seas is based on numerical model results and broad-scale observations. There is thus a need for more detailed shelf-break observational programs.
