Abstract
Discrete environmental stressors, such as prolonged periods of extreme temperature or low oxygen, threaten the functioning of marine ecosystems. While considerable attention has been given to studying extremes occurring in isolation, our understanding of such events co-occurring in the water column–referred to as multi-stressor events or compound extremes–is still limited, despite their potentially synergistic effects on individual species. We use a historical ocean model simulation with biogeochemistry to characterize the frequency, intensity, and duration of multi-stressor events (temperature, chlorophyll, and oxygen) in the California Curr... more
