This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) provides $932,280 to Carnegie Mellon University to conduct research on how emissions from marine plankton communities lead to atmospheric particle nucleation. The key objectives are to: 1) verify a nucleation potential model for complex mixtures, 2) measure nucleation reactions and emission profiles of tank-grown phytoplankton, 3) predict seasonal and spatial variation in emissions and nucleation from natural Gulf of Maine plankton communities, and 4) evaluate spring/fall marine emissions and nucleation at the Gulf of Maine. This research aims to expand nucleation measurements in difficult-to-access regions and provide a method for predicting nucleation rates in diverse environments. The award also includes plans to develop an atmospheric chemistry and climate curriculum for local high schools. The project will be performed at Carnegie Mellon University from Feb 2024 through Jan 2027.
