CP41B:
The Inner Shelf: Impacts of Interconnected Processes II

Session ID#: 92865

Session Description:
The inner shelf, which extends from the surfzone to about 50m depth, is a region with complex dynamics and high ecological importance. Water properties and suspended material---including temperature, salinity, nutrients, sediments, and biota---are mixed and advected by wind-driven currents, surface waves, barotropic tides, submesoscale eddies, and nonlinear internal waves. In this relatively shallow region, surface and bottom boundary layers frequently overlap and topographic features play a critical role in the dynamics. Disentangling how different temporal and spatial scales contribute to variability in this region is key to understanding the relative importance of interconnected processes. For example, the variability of stratification and temperature on the shelf is modulated by processes including upwelling, internal waves, and headland-flow interactions that evolve on timescales of hours to days while also having cumulative impacts on seasonal and interannual timescales. This session invites new findings on the physical drivers of circulation, transport, cross-shelf exchange, and temporal variability on the inner shelf over event-, tidal-, low-frequency, and interannual timescales and a range of spatial scales.  Studies focused on regions removed from freshwater-driven systems are encouraged.
