- This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $625,065 to the Woods Hole Oceanographic Institution (WHOI) to conduct research on how micronutrient limitations, specifically iron and copper, impact the physiology and nitrous oxide production of ammonia oxidizing bacteria and archaea. The project aims to use stable isotopes of nitrogen and oxygen as tools to investigate how the availability of these key metals influences the growth,...
Federal Project Grant Award Summary The National Science Foundation's Division of Ocean Sciences awarded $194,008 to the Woods Hole Oceanographic Institution (effective July 1, 2026 through June 30, 2029) under the Geosciences program (CFDA 47.050) to investigate photochemical production of nitrous oxide (N2O) in ocean surface waters. The research will characterize the mechanisms of photochemodenitrification, identify additional substrates and reactions leading to photochemical N2O formation, determine the action spectrum and efficiency of this photochemical process, and integrate photochemical production rates into broader N2O budget models. This collaborative research addresses a significant discovery that sunlight-driven, non-biological reactions—not only biological processes—produce N2O in oxygenated surface waters, revealing a previously unrecognized pathway in the global nitrogen cycle that explains persistent N2O oversaturation across the world's oceans. The project will deliver primary research outputs including mechanistic characterization of photochemical nitrogen transformations, quantified photochemical production rates, and integrated modeling data suitable for incorporation into global biogeochemical cycles. Additional deliverables include educational and outreach activities targeting graduate and undergraduate students, as well as public engagement to communicate findings regarding the ocean's role in atmospheric composition and ozone layer dynamics. The research directly addresses concerns related to air quality, stratospheric ozone destruction, and greenhouse gas emissions by elucidating a previously underappreciated source of atmospheric N2O.
