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...
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 $438,331 project grant to the University of Massachusetts Dartmouth under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 1, 2023 through March 31, 2026. The research aims to characterize amino acid nitrogen isotopes in phytoplankton and advance understanding of isotopic patterns produced under varying physiological conditions. Investigators and students will explore how different...
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...
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...
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 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...
The National Science Foundation Division of Ocean Sciences awarded a $299,978 Project Grant to the Massachusetts Institute of Technology for the period of December 1, 2021 through November 30, 2023. The grant supports MIT's "EAGER: Testing the Galápagos as a Long-Term Monitoring Site for Nitrous Oxide Emissions from the Pacific Oxygen Deficient Zones" project under the Geosciences program (CFDA 47.050). The Geosciences program aims to strengthen the national scientific enterprise...
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...
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...
