26 Research Questions and Objectives Hypoxic Effect Does hypoxia impact ecosystem functioning by altering rates of benthic nutrient regeneration, greenhouse gas regulation and reactive N removal? Station Effect How does the response to hypoxia vary across regions that have different oxygen dynamics? Can we see evidence of hypoxic legacy?
