EP34B:
Biophysical Dynamics of Eastern Boundary Upwelling Ecosystems in a Changing Ocean: Closing the Gap Between Wind Stress and Ecosystem Productivity I Posters


Session ID#: 37934

Session Description:
Eastern boundary upwelling ecosystems (EBUE) play a significant role in ocean productivity and also regulate regional climate variability. The strong coupling between atmospheric forcing, ocean circulation, biogeochemical cycling, and fisheries has long motivated multidisciplinary studies that are now common in EBUE. However, the relationships between atmospheric forcing and ecological responses in these ecosystems are not straightforward, and can be modulated by variability or change in nutrient stoichiometry, oxygen concentrations, nutricline depth, upwelling phenology, and mesoscale and submesoscale circulation, among other things. Many of these processes, and their impacts on the ecosystem, are sensitive to climate variability and are expected to be influenced by climate change. In this session, we welcome contributions that (i) investigate processes that may be crucial for resolving the relationships between atmospheric forcing and ecosystem productivity in EBUE, and (ii) describe advances in observational tools and modeling approaches for understanding the multi-faceted dynamics of EBUE. In this session we seek to improve the community’s understanding of the processes and resolutions required (in both models and observations) to properly describe relationships between physics, biogeochemistry, and higher-trophic-level populations of interest, and to accurately project and interpret the dynamics of these relationships under the influence of climate variability and change.
