The world’s major ocean basins are characterized by narrow, swift, persistent flows along their western boundaries and relatively shallower, slower and broader current systems along their eastern boundaries. Such eastern boundary current systems generally consist of meandering longshore equator-ward coastal currents, undercurrents that transport properties poleward, offshore jets and rich eddy fields. Longshore wind stress produces rapid coastal upwelling and these currents are the locations of some of the highest biological productivity in the world’s oceans.
Nonlinear dynamics including eddy-mean flow and wave-eddy interactions, barotropic and baroclinic instability processes, and flow over topography increase the complexity of these systems and can induce intrinsic low-frequency variability over a broad range of spatial and temporal scales. Understanding the mechanisms that produce the structures and variability of these boundary currents is necessary to further understand their roles in delivering provisioning, regulatory and/or cultural ecosystem services within expanding oceans economies in these regions.
In this symposium we welcome contributions on all aspects of oceanic eastern boundary current systems, based on experimental, theoretical and numerical modeling studies. We also welcome contributions that connect ecosystems, physical processes and derived ecosystem services.
