PO23B:
New Insights into Shelf and Slope Processes from Interdisciplinary Studies and the Use of Autonomous Platforms II


Session ID#: 11439

Session Description:
The exchanges of mass, energy and constituents between the continental shelf and the deep ocean have a profound impact on the physical, biological and biogeochemical properties of marine systems. The on-shelf flux of nutrients from the deep-ocean, for example, promotes the growth of phytoplankton while the export of organic material from the shelf to the deep-ocean can contribute to long-term carbon storage. Regional and local-scale differences in shelf-slope exchange can be related to a range of factors, including air-sea interactions, the formation and persistence of fronts, the proximity of strong boundary currents, tidal forcing, shelf/slope configuration and the complexity of local bathymetry. In this session we invite contributions that emphasize inter-disciplinary approaches to the study of shelf-slope processes. Contributions are encouraged from observational and modeling studies that address the coupling of physical, biogeochemical and biological processes in the outer shelf to upper slope region in eastern and western boundary systems as well as submissions that illustrate similarities and differences in shelf-slope exchange across shelf margin settings, seasonal and inter-annual patterns, and the role of episodic or extreme events.
