Last summer, scientists met at the University of Washington to address alarming findings concerning the rapid acidification of the world’s oceans. Experts at that symposium warned that wildlife in the Salish Sea, from salmon to shellfish, may start to see significant effects from changing water chemistry within the next 10

Decadal variability in twentieth-century ocean acidification in the California Current Ecosystem
Oceanic uptake of CO2 can mitigate climate change, but also results in global ocean acidification. Ocean acidification-related changes to the marine carbonate system can disturb ecosystems and hinder calcification by some organisms. Here, we use the calcification response of planktonic foraminifera as a tool to reconstruct the progression of ocean
Ocean acidification and hypoxia can have opposite effects on rockfish otolith growth
Highlights • Elevated CO2 and reduced dissolved oxygen have opposite effects on otolith (earstone) development in juvenile copper and blue rockfish. • Increased CO2 levels resulted in otoliths being larger in area for a relative fish body size in blue rockfish. • Reduced dissolved oxygen levels results in otoliths being
