Cross-Shore Fluxes in Ocean Boundary Currents: Biogeochemical and Ecological Consequences II Posters

Session ID#: 85170

Session Description:
This session invites contributions on the processes underlying cross-shore fluxes in eastern and western boundary currents and their biogeochemical and ecological consequences.  Cross-shore transport mediated by coastal filaments, eddies, Ekman transport, and other processes advects carbon, dissolved nutrients, and organisms.  Offshore advection can be a loss term for populations in coastal regions and support offshore communities through nutrient and organic matter inputs across Eastern Boundary Currents, while warm and cold-core rings transport communities through Western Boundary Currents.  Cross-shore transport of organisms from nearshore to the offshore, or vice versa, also leads to locally altered community characteristics, gene expression, food web structure, and the occurrence of biological “hot-spots.” Transport creates challenges for life history closure that may lead to diel vertical migration, dormancy, or other types of behavior that increase residence time in specific ocean provinces.  Cross-shore transport also creates spatial decoupling of New Production and vertical export, meaning that the classical steady-state assumption that local new production is balanced by local export production does not hold.  In situ field studies, satellite analyses, Lagrangian and modeling studies that analyze the mechanisms and consequences of cross-shore fluxes are all encouraged.  Studies that address long-term variations in transport processes are also appropriate.
