March 17, 2026 — A combination of conservation measures has helped the industry weather the effects of overfishing. Now, warming and acidifying oceans are posing new threats and prompting new solutions.
A team of researchers co-led by UConn Associate Professor of Marine Sciences Samantha Siedlecki, Shannon Meseck, of NOAA’s Northeast Fisheries Science Center, and Robert “Bobby” Murphy, a social scientist with NOAA’s Northeast Fisheries Science Center, is exploring how environmental data can be used to develop a new management approach adapted for and responsive to a changing ocean. With the support of a three-year grant of just over $1 million from NOAA’s Ocean Acidification Program (OAP), the project will integrate oceanographic modeling, industry engagement, and socioeconomic research to create actionable strategies for industry and management. The project is one of six announced by OAP in November aimed at helping U.S. coastal communities adapt to ocean acidification.
“This is one of the earliest attempts to forecast optimal regions for Atlantic sea scallop growth, based on both carbon content and ocean temperature,” says Siedlecki.
Ocean acidification occurs when carbon dioxide (CO2) sent into the atmosphere by the burning of fossil fuels and other human activity is absorbed by the oceans. Like sponges, the oceans of the world soak up about one-third of the CO2 generated by humans. Once dissolved in seawater, the CO2 forms carbonic acid, which increases acidity and reduces the carbonate ions that shell-building sea life, like sea scallops, need to form shells and skeletons.
