Session Description:
The ocean’s mid-latitude eastern boundary currents support elevated levels of primary and secondary production that sustain lucrative fisheries and attract an abundance of top predators. However, populations in these systems exhibit high degrees of variability in productivity and/or distribution at interannual to multidecadal time scales, challenging efforts to describe ecosystem health and develop effective strategies of resource management. Coupling between physical and ecological processes in eastern boundary current systems has stimulated multidisciplinary studies that aim to better describe the sensitivity of biogeochemical properties and biological communities to climate variability and climate change. Variability in the intensity, spatial distribution, and seasonal timing of wind-driven upwelling, changes in vertical stratification and mixing of the water column, differences in mesoscale and submesoscale features, and changes in the biogeochemical properties of these regions’ deep source waters have been proposed as critical factors influencing temporal variability in ecosystem conditions. In this session, we welcome presentations highlighting work (observational, conceptual, and/or numerical) contributing to better understanding of the dynamics of ecosystem response to climatic (both natural and anthropogenic) and hydrographic changes in eastern boundary current upwelling systems over interannual to centennial scales.
