The National Science Foundation awarded a $194,660 Project Grant to the University of Washington under the Geosciences federal grant program (CFDA 47.050) to fund collaborative research characterizing the evolving distribution of radiocarbon in the world's oceans. The five-year project, beginning in February 2021, will involve sampling and analysis of radiocarbon levels during research cruises conducted via the Global Ocean Ship-based Hydrographic Investigations Program and ships of...
This National Science Foundation (NSF) Project Grant under the Geosciences Program (CFDA 47.050) will support a collaborative research project to trace Pacific Ocean circulation and ventilation during the warm Pliocene epoch. The $387,909 award, made on August 15, 2024, will fund the generation of paleoceanographic records to test models suggesting a strong overturning circulation in the North Pacific during this period. The research will examine redox, temperature, and productivity proxies in...
This $163,915 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project investigating changes in carbon uptake and storage in the Pacific Ocean during the Pliocene, a warm period approximately 3 million years ago. The primary objectives are to quantify the marine carbon response to temperature-sensitive mechanisms within the ocean, with the goal of better predicting carbon storage during future climate warming. The...
This $308,515 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study changes in pelagic ecosystem function and their impact on the carbon cycle from the Eocene to Oligocene periods (56-33.9 million years ago). The project aims to reconstruct changes in the South Atlantic subtropical gyre ecosystem and determine how these changes affected carbonate production and preservation during a time of...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $374,314 to Yale University to investigate changes in carbon uptake and storage in the Pacific Ocean during the Pliocene era, around 3 million years ago, as an analog for understanding the ocean's response to modern climate warming. The researchers will use data and models to quantify the impacts of temperature-sensitive mechanisms, such as circulation changes and biological processes,...
The University of California Santa Cruz received a two-year, $142,510 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050). The grant funds collaborative research to uncover marine carbon chemistry dynamics during deglaciation through the use of boron isotopes and radiocarbon dating. The research aims to expand fundamental knowledge of the integrated Earth system by increasing understanding of atmospheric, earth, and ocean sciences processes. The grant...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will provide $709,875 to the Woods Hole Oceanographic Institution (WHOI) from September 1, 2024 to August 31, 2027 to reconstruct intermediate and deep water formation in the North Pacific over the past 25,000 years. The project will generate new stable isotope and trace element data from benthic foraminifera to calculate the air-sea component of carbon-13 (δ13Cas), a promising water mass tracer for...
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 $350,334 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Delaware. The grant will support a research project to reconstruct changes in deep ocean circulation and water mass geometry in the South Pacific Ocean over the past 2 million years, with a focus on the Mid-Pleistocene Transition period. The project will use neodymium isotopes preserved in fossil fish teeth and foraminifera as proxies to investigate the relationship...
This three-year Project Grant from the National Science Foundation Division of Ocean Sciences provides $185,519 to The Trustees of Columbia University for collaborative research probing the ventilation efficiency of the deep ocean with conservative dissolved gas tracers in archived samples. The research directly supports the goals of the NSF's Geosciences program (CFDA 47.050) to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean...
This Project Grant award of $599,974 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project by the University of Washington to reconstruct the history of ocean ventilation and circulation in the Northeast Pacific over the past 23,000 years. The key objectives are to improve understanding of the marine carbon cycle and enhance the utility of radiocarbon dating for marine sedimentary records. The project will leverage sediment cores and apply genomic techniques to identify marine microfossils and terrestrial plant debris. The resulting reconstruction, calibrated to the atmospheric radiocarbon record, will provide insights into Pacific Ocean circulation changes during past climate events. In addition to the research, the project includes broader impact activities such as training students, developing new course content, and creating resources to improve participation in seagoing research. This award will be executed over a 5-year period from August 2025 to July 2030.
