This National Science Foundation (NSF) Geosciences program project grant award of $550,590 to the University of South Carolina (USC) aims to investigate nitrous oxide (N2O) cycling in the sediments of the Northern Benguela Upwelling System off the west coast of Africa. The multidisciplinary research team, including geochemists and microbial ecologists, will determine the net sediment-water column flux of N2O, the rates of N2O production and consumption by different processes, and the influence...
This three-year project grant from the National Science Foundation Division of Ocean Sciences, titled "COLLABORATIVE RESEARCH: QUANTIFYING NITROUS OXIDE SOURCES ACROSS AN OXYGEN GRADIENT IN THE NORTHERN BENGUELA UPWELLING SYSTEM," provides $467,135 in funding to Florida State University from September 2021 through August 2024. The project aims to strengthen understanding of integrated Earth systems by quantifying sources of the greenhouse gas nitrous oxide across oxygen concentration...
This $292,831 project grant awarded by the National Science Foundation's Geosciences program aims to simultaneously measure nitrous oxide (N2O) production and consumption in ocean environments with varying dissolved oxygen levels. The research will be conducted by Arizona State University and will: 1) quantify N2O production and consumption rates as dissolved oxygen decreases from oxic to anoxic conditions, 2) determine the degree to which N2O consumption in anoxic zones balances increased...
This $582,005 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by The Trustees of Princeton University to investigate nitrous oxide (N2O) consumption in the surface ocean. The research aims to determine the factors that control or stimulate N2O reduction in surface waters and characterize the microbes responsible for the process. Specifically, the investigators will perform 15N tracer incubations to measure the rate of N2O reduction...
The University of Massachusetts Dartmouth received a $336,586 Project Grant from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) to conduct collaborative research on deciphering the mechanisms of marine nitrous oxide (N2O) cycling. The research team, which includes one postdoctoral investigator, two graduate students, and several undergraduates, will use stable isotopes, molecular markers, and in-situ rate measurements to study N2O production and consumption in the...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $467,675 Project Grant to the University of South Carolina (USC) under the Geosciences program (CFDA 47.050) to study nitrous oxide cycling in the Arabian Sea. The award supports research to quantify rates of nitrous oxide production and consumption in marine oxygen-deficient zones using stable isotopes, molecular markers, and in-situ incubation experiments. The project will involve a team of U.S. and Indian...
The National Science Foundation Division of Ocean Sciences awarded a $776,194 Project Grant to Stanford University from September 2021 through August 2024. The grant supports collaborative research to quantify nitrous oxide sources across an oxygen gradient in the northern Benguela upwelling system off the coast of Namibia and Angola. This research aligns with the Geosciences program's goal of expanding fundamental knowledge and understanding of the integrated Earth system through basic research...
The University of South Carolina received a $147,450 Project Grant award from the National Science Foundation Division of Ocean Sciences Geosciences program (CFDA 47.050) to conduct collaborative research exploring the dynamics of nitrous oxide in the Southern Benguela upwelling system from May 1, 2023 to April 30, 2027. The university will investigate nitrous oxide cycling in the region, estimate sea-to-air fluxes of nitrous oxide to the atmosphere, and examine what drives changes in nitrous...
Florida State University was awarded a three-year, $142,382 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050). The grant will support collaborative research investigating the source and flux of dissolved organic carbon released from methane seeps to the deep ocean. As part of the Geosciences program's mission to expand fundamental knowledge of the integrated Earth system through basic research, this project will enhance understanding of carbon cycling...
The University of Connecticut received a $899,677 Project Grant award from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to conduct collaborative research exploring the dynamics of nitrous oxide in the Southern Benguela upwelling system from May 1, 2023 to April 30, 2027. Under the award, the University of Connecticut will partner with the University of South Carolina to measure nitrous oxide concentrations and sea-to-air...
The National Science Foundation awarded a $280,354 project grant under its Geosciences program to Florida State University (FSU) to investigate sedimentary nitrous oxide (N2O) production and consumption in the Northern Benguela Upwelling System off the west coast of Africa. The 3-year project will utilize multi-isotope tracing and microbial ecology approaches to determine the net sediment-water column flux of N2O, production and consumption rates, and the link between measured rates and active microbial processes. The research aims to improve scientists' ability to predict future greenhouse gas emissions from this important oceanic oxygen-deficient zone. The project will support 3 undergraduate and 3 graduate students at FSU and include collaboration with researchers in South Africa and Namibia, with student internships hosted at USC.
