This $442,689 project grant from the National Science Foundation Division of Ocean Sciences 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. The grantees, led by the University of Connecticut Office of Sponsored Programs, will investigate how phytoplankton access subsurface nitrogen at Station ALOHA in the North Pacific Subtropical Gyre. Researchers will sort phytoplankton...
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...
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...
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 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $126,324 to Texas A&M University, with a project period from July 2024 to June 2027, will support research to determine the role of dissolved organic nitrogen (DON) in sustaining biological productivity in the nutrient-poor subtropical North Pacific Ocean. The key activities under this award include: conducting a one-month research expedition in the North Pacific to study DON production,...
This National Science Foundation (NSF) Geosciences program Project Grant (CFDA 47.050) awarded to the University of New Hampshire (UNH) provides $155,302 to support collaborative research on the contribution of allochthonous (externally-derived) dissolved organic nitrogen (DON) to biological nitrogen demand in the subtropical North Pacific Ocean. The research expedition will depart from San Diego, CA and end in Honolulu, HI to study the production, accumulation, chemical composition, and...
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...
This Project Grant award for $291,764 from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to study a newly discovered Synechococcus ecotype that has lost the ability to utilize nitrate, a key process in the marine carbon cycle. The project will: (1) collect and isolate this novel Synechococcus strain from the iron-limited Northeast Subarctic Pacific, (2) determine the seasonal and spatial dynamics of different Synechococcus nitrogen-utilization ecotypes in this...
This National Science Foundation (NSF) award under the Geosciences program (CFDA 47.050) will provide $344,271 to the University of California, Santa Cruz (UCSC) from January 1, 2025 to December 31, 2027 to characterize the composition, activity, and symbiotic nature of Rhizosolenia mat communities and their contribution to the nitrogen cycle in the North Pacific Subtropical Gyre. The project aims to determine whether Rhizosolenia mats, a type of phytoplankton aggregate, obtain nitrogen from...
This National Science Foundation Project Grant under the Integrative Activities program (CFDA 47.083) provides $221,015 to the University of New Hampshire from February 2022 to January 2024 to investigate changes in Arctic Ocean phytoplankton and track the vertical export of organic carbon they produce. Working with optical oceanography experts at the Scripps Institution of Oceanography, the University will analyze data from 2010-2021 field campaigns measuring inherent and apparent optical...
