The California Current is one of only four temperate upwelling systems in the world. Seasonal upwelling of nutrient-rich waters fuels a highly productive ecosystem, supporting biodiversity and fisheries that, along with coastal tourism, are a foundation of California’s economy.
Yet California’s coasts and oceans are also under increasing threat. Relatively few fisheries are managed based on robust scientific assessments, and more needs to be done to avoid overfishing and reduce bycatch. Plastics and other pollutants are pervasive. Climate change compounds these challenges. Ocean chemistry is changing. Sea levels and temperatures are rising – threatening important resources, biodiversity, and human populations.
Fortunately, the coastal and ocean ecosystems of California are bolstered by a network of marine protected areas and some of the most science-based marine policies in the world. Conservancy scientists look to build on those foundations by applying science and technology to enhance resilience of marine resources in the face of emerging threats.
