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 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $143,250 to the University of Southern California to conduct collaborative research on controls on aerobic methane oxidation in the deep sea. The goal is to understand how differences in oxygen concentrations affect the ability of microbes to consume methane released from natural gas seeps on the ocean floor. The researchers will use custom-built instruments to measure methane...
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 (CFDA 47.050) Project Grant award of $348,452 to the University of North Carolina at Chapel Hill (UNC-CH) supports collaborative research to investigate controls on aerobic methane oxidation in deep-sea gas seeps. The project aims to use custom instrumentation to measure methane consumption rates and monitor microbial communities under varying oxygen concentrations at gas seep sites offshore Louisiana and Oregon. The in-situ measurements...
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 $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...
The National Science Foundation's Geosciences program awarded a $299,818 EAGER grant to The Research Foundation For The State University Of New York (doing business as Stony Brook University) to investigate a chemical mechanism that could utilize naturally generated chlorine from sea-spray aerosol and iron from Saharan dust to oxidize and remove methane from the atmosphere. The project aims to evaluate the viability of adding chlorine to the atmosphere as a means of mitigating climate change...
This $155,698 federal Project Grant awarded by the National Science Foundation's (NSF) Integrative Activities (IA) program, CFDA #47.083, supports a collaborative research project led by Mississippi State University (MSU) to study methane seepage along the U.S. Atlantic margin. The project aims to investigate the biogeochemical and geological controls on recently discovered methane seeps in the northern U.S. Atlantic margin, in order to improve understanding of methane's role in climate. Key...
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...
The University of Georgia Research Foundation, Inc. was awarded a $199,278 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to measure methane efflux from river influenced coastal marine sediments. Over a three year period ending in September 2025, the awardee will conduct fieldwork during two cruises off the southeastern coast of Louisiana to directly measure benthic fluxes of oxygen and methane using in situ...
