WebA new review of the effects of hypoxia and OA on marine animals shows that effects of these conditions are complex and unpredictable; vary among species and life stage; and depend upon whether hypoxia or low pH occur alone or in tandem. Results show that hypoxia and OA can affect organism survival and growth. The amount of oxygen in any water body varies naturally, both seasonally and over time. This occurs due to a balance between oxygen input from the atmosphere and certain biological and chemical processes, some of which produce oxygen while others consume it.
