Arctic coastal and continental shelf dynamics
Session ID#: 159709
Session Description:
Arctic coastal and shelf systems are changing rapidly in response to temporal and spatial declines in sea-ice coverage, warming air and water temperatures, increasingly energetic wave climates, changes in river discharge and coastal erosion, and related processes. These changes have known impacts on rates of coastal erosion and energy in the coastal ocean, but the feedbacks among processes are in many cases poorly constrained. This session invites presentations related to coastal and continental shelf dynamics including erosion processes, sediment transport, biogeochemical cycling, geomorphic evolution of coastlines and shelves, seabed geotechnical properties, shelf stratigraphy, bathymetric mapping efforts, and physical oceanographic processes of estuaries, lagoons, and shelves as well as interactions with shelf-break processes. Observational and modeling studies are welcome, from local, regional, or pan-Arctic settings.
