Evaluating ocean acidification vulnerability and interactions among traditional and coastal Alaska industries

Why we care
Many marine species affected by ocean acidification (OA) contribute to Alaska’s highly productive commercial fisheries and traditional subsistence ways of life. Concern exists that acidification will cause ecosystem-level shifts, diminishing the overall economic value of commercial fisheries and reducing food security for communities relying on subsistence harvests. 

What we are doing
This project addresses acidification threats in south-central and southeast Alaska. It involves the development of decision support tools incorporating acidification risks into localized socio-ecological systems. The tools are based on a network of models representing acidification hazards, bio-ecological systems, and socioeconomic systems linked to adaptive actions.

Benefits of our work
This project is an exchange of knowledge between scientists, policy makers, and community stakeholders. The network of models creates decision support tools responsive to stakeholder concerns that reflect regional variation in community priorities and their ecological social and management context. The project synthesizes the best available science to determine the risks posed by ocean acidification.
