The National Science Foundation awarded a $209,385 Project Grant to the Woods Hole Oceanographic Institution from November 1, 2021 to April 30, 2023 under the Geosciences program (CFDA 47.050). The grant will support research to constrain nitrogen sources and recycling efficiency in hot subduction zones using fluid inclusions in mineral separates from mafic lavas. The Geosciences program seeks to strengthen the national scientific enterprise through expanded fundamental knowledge and...
This $167,576 National Science Foundation project grant under the Geosciences program (CFDA 47.050) funds research into constraining nitrogen sources and recycling efficiency in subduction zones. The Williamstown, MA-based awardee, President and Trustees of Williams College, will conduct research at the Woods Hole Oceanographic Institution to quantify nitrogen outputs from Central American and Chilean volcanoes and identify nitrogen sources in arc magmas. Using fluid inclusions in mineral...
This $195,997 Project Grant awarded by the National Science Foundation's Geosciences program (CFDA 47.050) to Brown University will support collaborative research on understanding nitrogen cycling in subduction zones. The project aims to provide new constraints on the distribution and behavior of nitrogen as it is subducted into the Earth's mantle and then potentially returned to the surface through volcanic activity. Key planned activities include measuring nitrogen composition in subduction...
This $387,090 Project Grant, awarded by the National Science Foundation's Geosciences Program (CFDA 47.050), will support a collaborative research effort to enhance understanding of nitrogen cycling in deep-sea hydrothermal vent ecosystems. The project will employ specialized high-pressure equipment to conduct experiments measuring rates of nitrogen loss, recycling, and microbial assimilation across redox gradients at two distinct seafloor vent habitats. This work aims to address limitations...
This $193,980 Project Grant, awarded by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050), supports a research project to evaluate the continental crust as a reservoir for Earth's nitrogen and constrain the nitrogen abundance of primitive arc magmas. The project will analyze nitrogen levels in continental crust samples from California and Arizona to determine how much nitrogen is stored in the crust and how it is exchanged with the Earth's interior at subduction...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) project grant awarded to Lehigh University provides $141,748 to investigate nitrogen cycling in deep-sea hydrothermal vent ecosystems. The 3-year project, beginning September 1, 2024, will employ specialized high-pressure equipment to measure rates of nitrogen loss, recycling, and microbial assimilation across redox gradients at seafloor vent habitats. This research aims to enhance understanding of how these extreme...
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...
This Project Grant award from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), provides $869,346 to the Woods Hole Oceanographic Institution to study nitrogen cycling and nitrous oxide production in the Atlantic Ocean. The key products and services to be delivered through this 3-year project include: Measuring and mapping the distribution and isotopic composition of nitrous oxide in the Atlantic interior using a large dataset of over 950...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $343,290 Project Grant to the Woods Hole Oceanographic Institution (WHOI) for a 2-year Postdoctoral Fellowship. The grant, funded under the NSF Geosciences (CFDA 47.050) program, will support research to characterize the composition of the Pacific mantle using nitrogen and noble gas isotopes. Specifically, the project will analyze oceanic basalt samples from seamounts near the East Pacific Rise to identify recycled and...
The National Science Foundation Division of Ocean Sciences awarded a $313,465 Project Grant under the Geosciences federal grant program (CFDA 47.050) to The Marine Biological Laboratory in Woods Hole, Massachusetts for the period of April 1, 2022 through March 31, 2025. The grant will support research examining the potential importance of intracellular nitrate cycling in nitrogen cycling within marine sediments. The awardee will measure rates of intracellular nitrate cycling and other major...
