Through model experiments, COCOA will investigate feedback processes, associated with hypoxia and loss of key biological functions, and examine the potential existence of alternative stable states leading to hysteresis responses and identify critical thresholds associated with such responses. COCOA will use models and statistical analyses to examine changes in nutrient retention over the past and in the future given scenarios for climate change and management responses. Consequences of altered nutrient pathways on coastal ecosystem services will be assessed and used for identifying optimal management strategies.
