EC12B:
The Dynamics of Buoyancy Driven Flows in Estuaries and River Plumes and on the Continental Shelf II


Session ID#: 11341

Session Description:
The mixing and dynamics of river water entering the ocean profoundly impacts ecological and physical processes in the estuary and coastal ocean, representing processes at the interface between fresh and ocean waters, and also at the interface between terrestrial and marine ecosystems. The dynamics of buoyancy driven flows are complex due to the large range of scales and include stratified mixing, internal waves and frontal processes, among others. These buoyancy-­driven flows are influenced by many different factors, including freshwater discharge magnitude, winds, surface gravity waves, tides and bathymetry. Understanding the complex dynamics of buoyancy driven flows on the shelf is necessary for appropriate management of these valuable and sensitive coastal ecosystems. We welcome submissions that investigate buoyancy driven flow in estuaries and over the continental shelf over a wide spectrum of scales, including observational, numerical, theoretical, laboratory and remote sensing investigations.
