This research will cover a wide range of experimental...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $603,364 project grant to the University of Rochester to support collaborative research on improving estimates of geologic methane emissions to the atmosphere from microseepage. The three-year award, made under the Geosciences program (CFDA 47.050), will fund research from February 2021 through January 2024 to strengthen understanding of the integrated Earth system through expanding knowledge of...
- This National Science Foundation (NSF) Geosciences program Project Grant award of $518,578 to Michigan State University (MSU), with a period of performance from March 1, 2024 to February 28, 2027, will investigate the Holocene biogeochemical evolution of the Great Lakes system. The project will collect sediment cores from Lakes Superior, Huron, and Erie to analyze geochemical proxies, including mercury isotopes, nutrient concentrations, and redox-sensitive elements. This research aims to...
- This $1,038,171 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into methane efflux from river-influenced coastal marine sediments in the Gulf of Mexico. The Louisiana Universities Marine Consortium will measure methane fluxes from coastal sediments into Gulf waters using an in situ lander to collect benthic flux measurements of oxygen and methane. Sediment microprofiles of oxygen and sulfide will also be analyzed. Naturally occurring...
- This Project Grant award from the National Science Foundation's (NSF) Geosciences program totaling $429,823 supports a collaborative research effort to investigate the Holocene biogeochemical evolution of the Great Lakes. The research team from Central Michigan University and Michigan State University will collect sediment cores from Lakes Superior, Huron, and Erie to analyze elemental and isotopic geochemical cycles over geologic time. This work will provide insights into past productivity,...
- The National Science Foundation awarded a $410,518 three-year Project Grant to The University of Puget Sound under the Geosciences program (CFDA 47.050) to conduct research on aerobic methane production in ocean environments. The university will collaborate with scientists in the U.S. and Israel to study the microbial processes that produce methane through the degradation of organic compounds in the surface waters of the North Pacific and North Atlantic oceans. Researchers will measure methane...
- This $180,000 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a postdoctoral fellowship project to study the hydrobiogeochemical controls on anaerobic oxidation of methane and methane emissions in wetland hyporheic zones. The project, led by Dr. Samuel Shaheen in collaboration with Drs. G.-H. Crystal Ng and Cara Santelli at the University of Minnesota, will integrate field, experimental, and modeling work to examine how microbial-scale...
- This three-year, $294,092 National Science Foundation project grant will fund research at the University of Rochester to improve understanding of open ocean methane sources and sinks. The research aims to determine dominant biological sources of methane in surface waters through modeling of methane concentration data. The model will quantify methane supply from seafloors in low-oxygen zones and whether this methane is consumed before escaping to the atmosphere. The optimized global model will...
- This $586,557 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research initiative to develop artificial intelligence (AI) models that can leverage gene sequence data to better understand ecosystem processes, with a focus on methane seep habitats. The project will collect new microbial samples from methane seeps off the coasts of Oregon and Washington and employ novel natural language processing AI approaches to predict...
This $848,801 Project Grant, awarded by the National Science Foundation's Geosciences Program (CFDA 47.050), will fund research to constrain methane emissions and sources in the North American Great Lakes system. The project will involve three research cruises to measure methane levels and related physical and biological properties in the surface waters of all five Great Lakes. Existing and new data will be combined to capture seasonal trends and potential flux hotspots. Machine learning models will be used to map methane disequilibrium between the lake surface and air, enabling high-resolution calculation of the lake-atmosphere methane flux. Researchers will also conduct incubation experiments and stable isotope analyses to construct methane budgets for each Great Lake and employ radiocarbon fingerprinting to trace the contribution of fossil methane. This research aims to provide critical data to improve models estimating global freshwater methane emissions, which may currently overestimate emissions from large lakes. The award was issued to the University of Rochester on August 15, 2025, with a scheduled completion date of July 31, 2028.
