The National Science Foundation's Division of Ocean Sciences awarded Princeton University $1,013,284 under the Geosciences program (CFDA 47.050) for a collaborative research project investigating photochemical production of nitrous oxide (N2O) in ocean surface waters. Beginning July 1, 2026, and concluding June 30, 2029, this project will characterize the mechanisms of photochemodenitrification—a non-biological, sunlight-driven pathway for N2O production—and assess additional substrates and reactions contributing to photochemical N2O formation. Key deliverables include determination of the action spectrum and efficiency of this photochemical process, integration of photochemical production rates into existing biogeochemical models, and mechanistic understanding of site preference in N2O isotope signatures relevant to global nitrogen budgets. Beyond primary research outputs, the project will produce educational and public engagement products, including dissemination of findings to non-scientific audiences to increase societal awareness of oceanic contributions to global biogeochemistry. The award will also support workforce development through research opportunities for graduate and undergraduate students at Princeton University's main campus in Princeton, New Jersey. This research directly addresses a significant gap in understanding persistent N2O oversaturation in the world's oceans, with implications for stratospheric ozone depletion, greenhouse gas emissions, and atmospheric air quality.Federal Project Grant Award Summary
