Physical, biogeochemical, and ecosystem change in Eastern Boundary Upwelling Systems: Past, Present and Future

Session ID#: 254211

Session Description:
Eastern Boundary Upwelling Systems (EBUS) play a disproportionately large role to global ocean productivity and provide critical ecosystem services that sustain coastal communities and economies. Their high biological productivity and biodiversity is intimately linked to complex physical and biogeochemical processes that undergo variability across a wide range of spatial and temporal scales. Thus, understanding the characteristics and variability of EBUS, and how climate change will affect these complex processes, is key to understanding and effectively managing for change in these marine ecosystems. In this session, we invite interdisciplinary contributions that explore the variability, predictability, and long-term changes in physical, biogeochemical, and ecological characteristics of EBUS or other upwelling systems. We particularly welcome studies that integrate observations and modeling approaches and focus on the physical, biogeochemical, and ecosystem state of the world’s EBUS.
