Exchange Processes Near Wide Arctic Canyons and Modeling Exchange Processes Near Wide Arctic Canyons

摘要

Understanding across-shelf exchange and shelf dynamics due to wind and buoyancy forcing. The main objective of this project is to describe and physically explain the dominant processes active within the wide Canadian Mackenzie Canyon prior to the onset of winter freezing. More specifically, the project will answer the following questions: (1) Do fresh Mackenzie shelf waters exit preferentially through Mackenzie Canyon; (2) How does the canyon circulation respond to local wind forcing; (3) Does an orographically induced wind-stress curl impact the canyon dynamics; (4) What are the spatial and temporal scales of vortices that populate this canyon.
