PS52A:
Boundary Currents and Shelf/Deep-Ocean Exchange II
Session ID#: 92587
Session Description:
The environmental health and societal uses of the coastal ocean are impacted not only by human activities on land but also by coastal to open-ocean exchange at the edge of the continental shelf – processes strongly influenced by energetic shelf-edge boundary currents. Boundary currents are themselves significant in global budgets of heat, freshwater and biogeochemical constituents, and are regions of strong air-sea interaction and frontal instabilities. Processes that exchange waters across the edge of the continental shelf are key controllers of coastal ocean water properties, including heat, freshwater, nutrients, and pollutants, thereby playing significant roles in coastal ecosystem dynamics. This session will explore processes that drive exchange across the continental shelf and slope, particularly where boundary currents are significant drivers of exchange, and potential topics include seasonal cycles and inter-annual variability, extreme events, submesoscale processes, and linkages to ecosystems. Observational, numerical, and theoretical efforts are welcome, with results from integrated model-observation systems particularly encouraged.
