The California Current Ecosystem (CCE), which brings cold, nutrient-rich waters to the U.S. West Coast, supports a wide range of important fisheries off California, Oregon, and Washington. In recent years, climate-driven changes in the CCE – from warming temperatures to ocean acidification and toxic algal blooms – are disrupting ocean habitats and species, and by extension the social and economic fabric of fishing communities on the coast. To better understand these changes, the Lenfest Ocean Program is funding Dr. Phillip Levin, The Nature Conservancy/University of Washington, and Dr. Alison Cullen, University of Washington, to assess the social and ecological vulnerability of fishing communities along the U.S. West Coast to changing ocean conditions.
