Ocean acidification and hypoxia plan outlines Oregon’s commitment to addressing climate impacts
CORVALLIS, Ore. – Oregon has a new roadmap for addressing rising ocean acidification and hypoxia – two climate change-induced conditions that could have widespread consequences for the state’s ocean ecosystem and the economy. Ocean acidification and hypoxia are significant threats to a wide range of marine mammals, from crabs to
