EP005:
Closing the gap between wind stress and ecosystem productivity in eastern boundary upwelling regions


Session ID#: 28650

Session Description:
Eastern boundary upwelling ecosystems contain the most productive fisheries in the world.  This immense fish production results from upwelled nutrients that stimulate high primary and secondary production.  However, the relationships between atmospheric forcing and the ecological productivity of these ecosystems are not straightforward.  Variability in nutrient stoichiometry, oxygen concentrations, nutricline depth, seasonal timing of upwelling, mesoscale and submesoscale variability, onshore geostrophic flow, and subduction of underutilized nutrients below the adjacent oligotrophic water masses are all examples of processes that can obscure the relationships between the intensity of upwelling-favorable wind stress and ecosystem productivity.  In this session, we welcome contributions that investigate processes that may be crucial for resolving the relationships between atmospheric forcing and primary and secondary production.  The objective of the session is to improve the community’s understanding of the processes and resolutions required (in both models and observations) to accurately describe the impacts of physical and biogeochemical drivers on fish and other higher-trophic-level populations of interest.  Such understanding will allow better interpretation of non-stationary empirical relationships between physical conditions and ecosystem state, and is necessary to properly project and interpret ecological impacts of climate variability and change.
