Decoupling of the Surface and Bottom‐Intensified Antarctic Slope Current in Regions of Dense Shelf Water Export

Abstract The Antarctic Slope Current is guided by the topographic gradient of continental slope and creates a dynamical barrier between shelf open ocean. current's vertical structure varies around continent affecting cross‐slope water mass exchange with consequences for loss, ventilation deep ocean, carbon uptake. surface‐intensified in many regions but bottom‐intensified dense overflows. This study investigates role overflows modifying dynamics flow using 0.1° global ocean‐sea ice model. occurrence bottom‐intensification tightly linked bottom speeds correlate on interannual time scales. A lack connectivity surface flow, however, suggests that along‐slope flows are coincidentally co‐located Current, rather than dynamically part current.
