Assessing vulnerability of the Atlantic Sea Scallop social-ecological system in the northeast waters of the US
Samantha Seidlecki (University of Connecticut), Lisa Colburn (NOAA Northeast Fisheries Science Center), Shannon Meseck (NOAA Northeast Fisheries Science Center)
Of the fisheries made up of calcifiers in the Northeast United States, the Atlantic sea scallop fishery is worth more than $500 million per year, is the second highest fisheries revenue in the United States, and the largest wild scallop fishery in the world. The vulnerability and resilience of fishing communities to the effects of warming and Ocean Acidification (OA) on Northeast species is dependent on their adaptive capacity in relation to both social and environmental exposure and sensitivity factors. Communities that harvest a diversity of species may adapt more easily than communities that specialize in one or a few species. The regional contribution of sea scallop to total regional landed value has steadily increased over recent decades as has fishing community dependence on it as a source of revenue.
Prior work projecting impacts to scallops in the region found that sea scallop biomass may decline by more than 50% by the end of the century with a large impact on the fishery (Cooley et al. 2015; Rheuban et al. 2018), but new tools and lab results are available for this proposed work that may alter this assessment. The team is working the hypothesis that a spatially- explicit regional projection of changes relative to sea scallop fishing zones can inform fishery management and allow communities that rely on Atlantic sea scallops to plan and become more resilient to future change. This work will develop a recommendation to management to assist scallop industry stakeholders and managers with changes in the fishery that result from projected OA and temperature changes.

Ocean and Coastal Acidification Thresholds from Long Island Sound to the Nova Scotian Shelf
Ruairidh Morrison, NERACOOS
How will nearshore and coastal ecosystems respond to ocean and coastal acidification in the Northeast? How will these changes affect human communities? An absence of actionable information and understanding of the dynamic nature of coastal acidification is a major challenge to Northeast seafood industry, resource managers, and coastal policymakers. This project will expand the existing Northeast Coastal Ocean Forecast System to develop actionable guidance for coastal water quality and marine resource managers through workshops and direct engagement. Workshops and focus groups will be held to determine information needs, decision scenarios, modeling priorities, and options for delivering actionable information for three specific users: (1) water quality managers and monitoring systems, (2) oyster growers, and (3) the wild harvest shellfishing industry. The research will focus on advancing ocean acidification detection and warning systems that take into account other environmental stressors in Northeast coastal waters.
