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...
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 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 University of South Carolina (USC) has been awarded a $422,847 Project Grant from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to conduct research on the influence of natural and human-induced activities on atmospheric nitrogen oxides (NOx) emissions and oxidation chemistry. The project aims to (1) quantify the interplay of volcanic eruptions with NOx oxidation chemistry and emissions, (2) assess the influence of natural climate change, specifically the Little...
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 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...
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 federal Project Grant award in the amount of $250,766 was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050). The award, titled "CAREER: CONSTRAINING ATMOSPHERIC NITRATE PRECURSORS AND CHEMISTRY ACROSS THE UNITED STATES (US)", aims to improve the prediction of atmospheric nitrate formation by focusing on nitrogen oxide precursor emissions and oxidation pathways. The project will utilize isotope observations from national monitoring sites,...
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...
This National Science Foundation (NSF) Division of Ocean Sciences project grant, CFDA # 47.050 Geosciences, will support collaborative research to decipher the mechanisms of marine nitrous oxide (N2O) cycling in the Arabian Sea using stable isotopes, molecular markers, and in-situ rate measurements. The $809,222 award to the Woods Hole Oceanographic Institution, a private non-profit research organization, will fund field work during the summers of 2024 and 2025, including a cruise of opportunity...
