Coastal upwelling ecosystems around the world are defined by wind-generated currents that bring deep, nutrient-rich waters to the surface ocean where they fuel exceptionally productive food webs. These ecosystems are also now understood to share a common vulnerability to ocean acidification and hypoxia (OAH). In the California Current Large Marine

Effects of multiple climate change stressors on gene expression in blue rockfish (Sebastes mystinus)
Highlights Marine fishes will be exposed to multiple stressors under climate change. Hypoxia and high pCO2 are both expected to cause shifts in energy metabolism. No signs of energetic shifts were observed at transcriptomic or enzymatic levels. Multiple stressor transcriptomes are not predictable based on responses to single stressors. Blue
Biogeochemical anomalies at two southern California Current System moorings during the 2014‐16 Warm Anomaly‐El Niño sequence
We analyzed impacts of the 2014‐15 Pacific Warm Anomaly and 2015‐16 El Niño on physical and biogeochemical variables at two southern California Current System moorings (CCE2, nearshore upwelling off Point Conception; CCE1, offshore California Current). Nitrate and Chl‐a fluorescence were < 1 μM and < 1 Standardized Fluorescence Unit, respectively,

Climate change could shrink oyster habitat in California
Ocean acidification is bad news for shellfish, as it makes it harder for them to form their calcium-based shells. But climate change could also have multiple other impacts that make California bays less hospitable to shelled organisms like oysters, which are a key part of the food web. Changes to
