Project Grant 2610907
- 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 $908,131 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), supports research to better understand how changing phytoplankton elemental use efficiencies may impact global ocean biogeochemistry as temperatures rise. A team of U.S. and U.K. researchers, led by the University of Southern California, will conduct laboratory experiments and field work to quantify the effects of temperature on nutrient elemental use...
- This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $625,065 to the Woods Hole Oceanographic Institution (WHOI) to conduct research on how micronutrient limitations, specifically iron and copper, impact the physiology and nitrous oxide production of ammonia oxidizing bacteria and archaea. The project aims to use stable isotopes of nitrogen and oxygen as tools to investigate how the availability of these key metals influences the growth,...
- This National Science Foundation Geosciences Program (CFDA 47.050) Project Grant award of $650,992 to North Carolina State University supports research to assess the role of marine bacteria and viruses in producing and cycling vitamin B1 and related compounds in the surface ocean. The 3-year project will conduct laboratory experiments to estimate the fluxes of these vital compounds from key bacterial groups and the impacts of temperature changes, which are critical for understanding plankton...
- The National Science Foundation, through its Geosciences Program (CFDA 47.050), awarded a $498,457 project grant to Texas A&M University to conduct research on the geochemical constraints on nitrogen fixation in the Southwest Pacific Ocean. The project aims to track the fate of newly fixed nitrogen, a critical nutrient for marine phytoplankton, to better understand how it is retained in the surface ocean or transported to the deep ocean. This collaborative research effort with French...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant, awarded to Bigelow Laboratory for Ocean Sciences, provides $158,036 to study monomethylmercury (MMHg) cycling in natural phytoplankton assemblages in the western North Atlantic Ocean. The overarching goal is to improve understanding of the factors controlling MMHg uptake by phytoplankton, which is crucial for modeling MMHg transfer through the marine food web. Key research activities include year-round...
- The National Science Foundation (NSF) Geosciences Program (CFDA 47.050) awarded a $824,656 project grant to the University of Washington (UW) to investigate the impact of iron availability on heterotrophic bacterial carbon consumption in the mesopelagic ocean's "twilight zone". The 3-year project, starting on May 1, 2025 and ending on April 30, 2028, will utilize a combination of laboratory studies and field experiments to test three related hypotheses on how iron and carbon...
- This $480,149 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project between the University of South Florida and the University of Hawaii. The research aims to measure iron isotopes in seawater samples from three GEOTRACES expeditions in the Pacific Ocean, producing an unprecedented data set. By combining these data with ocean biogeochemical modeling, the project will address important questions about the sources of...
- 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...
- The National Science Foundation (NSF) awarded a $899,999 Project Grant through its Geosciences (CFDA 47.050) program to the J. Craig Venter Institute (JCVI) on May 1, 2024. The grant will support collaborative research to characterize a novel blue copper ferritin protein in marine phytoplankton and explore how this protein may provide an ecological advantage in iron-limited ocean environments. The research aims to advance the understanding of how iron limitation impacts marine ecosystems and...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award in the amount of $516,885.00 seeks to provide a deeper understanding of how major biogeochemical cycles that support living marine resources will respond to climate warming. The project investigates the impact of ocean warming on the trace metal requirements and use efficiencies of marine nitrifying microorganisms, which play a critical role in the marine nitrogen cycle. Through well-controlled laboratory studies and field experiments, the project will systematically examine 1) the thermal effects on iron and copper requirements of marine ammonia-oxidizing archaea and bacteria, and nitrite-oxidizing bacteria, 2) the underlying molecular and biochemical mechanisms that facilitate thermally-driven adaptive responses, and 3) system-level feedbacks between global change, trace metal biogeochemistry, and marine nitrifiers. The project will train one postdoctoral researcher, three graduate students, and provide research opportunities for undergraduate students, while also conducting K-12 education and outreach activities. All data will be freely available through the Biological and Chemical Oceanographic Data Management Office.
