Project Grant 1829916

This Project Grant award from the National Science Foundation's (NSF) Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will investigate the photochemical breakdown of marine dissolved organic matter (DOM) and its impact on the global carbon cycle. The $683,778 award, valid from July 2023 to June 2026, will focus on studying the production rates and quantum yields of one and two-carbon photoproducts, such as carbon monoxide, dissolved inorganic carbon, formaldehyde, and...

The National Science Foundation Division of Ocean Sciences awarded a $371,107 project grant to the University System of New Hampshire to support the research project "COLLABORATIVE RESEARCH: WHAT CONTROLS THE MARINE REFRACTORY DOC RESERVOIR?" from July 15, 2021 through June 30, 2024. The grant funds basic research into the integrated earth system through the Geosciences program (CFDA 47.050). Specifically, the collaborative research project seeks to expand understanding of the controls...

This Project Grant award of $569,435 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research at Northeastern University to investigate the impact of plastic-derived dissolved organic carbon (PDOC) on the ocean's biological carbon pump. The core hypothesis being tested is that bacteria consuming PDOC compete with phytoplankton for key nutrients like nitrogen and phosphorus, reducing new production and the strength of the biological carbon pump,...

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...

This $309,557 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project at the University of Texas at Austin to investigate the fate of nitrogen in amino acids and the processes that contribute to the formation of refractory dissolved organic nitrogen (DON) in the ocean. The study will use stable isotope probing with 15N-labeled amino acids and controlled incubations to trace the fate of different amino acids as...

This $491,093 National Science Foundation Division of Ocean Sciences Project Grant supports research evaluating the contribution of small eukaryotes to nitrate-based new production in the North Pacific Subtropical Gyre. The grantees, led by Principal Investigator Granger at the University of North Carolina at Chapel Hill, will investigate how phytoplankton access subsurface nitrogen at Station ALOHA in the North Pacific Subtropical Gyre. The researchers will sort phytoplankton by size and...

This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $562,895.00 to the Regents of the University of Minnesota to conduct collaborative research on the role of the "colloidal shunt" in mediating interactions between the ocean's iron and carbon cycles. The research aims to better characterize the mechanisms and linkages between dissolved organic carbon, iron-binding organic ligands, and the formation of particulate iron in the ocean....

This $408,738 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate the effects of SUP05 bacterial cells and the viruses that infect them (phages) on nitrogen cycling in marine oxygen minimum zones. The project is led by the University of Washington, and aims to detail the combined impact of SUP05 cells and their associated phages on nitrogen transformation and loss processes in these ocean regions. Through a...

This $297,369 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research evaluating the contribution of small eukaryotes to nitrate-based new production in the North Pacific Subtropical Gyre. Over a three-year period ending November 2025, the University of Hawaii at Manoa will conduct laboratory and ship-based research to better understand how phytoplankton access subsurface nitrogen in surface waters during summer months. Researchers will sort phytoplankton...
