Project Grant 2503657
- This federal Project Grant award of $163,928 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate whether the deep Indian Ocean acted as an anomalous carbon reservoir during the last Ice Age. The research team, led by the University of Washington, will study microscopic marine fossils in sediment cores from across the Indian Ocean basin to determine if deep ocean carbon was abnormally old during this period. By analyzing the...
- The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $150,602 project grant to the University of California, Irvine to conduct collaborative research on potential anomalies in the Indian Ocean carbon reservoir across the last ice age. The project aims to use radiocarbon dating of microfossil remains to determine if the deep Indian Ocean stored substantial amounts of carbon during this period, which could have impacted global temperatures. The researchers will analyze...
- 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...
- The National Science Foundation (NSF) awarded a $568,104 Project Grant under the Geosciences program (CFDA 47.050) to the University of Delaware to collect high-resolution carbon isotope data on GO-SHIP cruises in the Indian and Pacific Oceans. This data will be used to constrain ocean carbon uptake and storage. The project centers on deploying a new instrument system that can efficiently measure the ratio of carbon-13 to carbon-12 (13C/12C) in dissolved inorganic carbon in seawater. This will...
- This $415,924 federal Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), will support collaborative research to investigate the large-scale dynamics of the tropical Indo-Pacific region during the Last Glacial Maximum. The project aims to reconstruct the tropical thermocline structure and wind patterns using ocean modeling and geochemical analysis of foraminifera sediment samples. This research will lead to a better understanding of how the...
- 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 $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 $632,314 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a research project led by the University of California San Diego's Scripps Institution of Oceanography. The project aims to provide a better understanding of the physical and biogeochemical processes driving carbon cycling in the equatorial Pacific Ocean. Using a combination of ocean models, autonomous observations, and satellite data, the project will characterize...
- This federal Project Grant award of $335,736 was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of California, Santa Cruz. The award supports a postdoctoral fellowship focused on investigating ocean circulation and ice sheet changes during the early Pleistocene era (2.5 to 1.7 million years ago) using deep-sea sediment cores from the North Atlantic. The key goals are to build a timeline of the sediment cores, characterize changes in ocean...
- This National Science Foundation Project Grant of $1,078,024 will fund research to reconstruct climate linkages across the tropical oceans over the last millennium through May 2025. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences, the University of Michigan will produce new paleoclimate records of sea surface temperature using the geochemistry of long-lived corals from the tropical North Atlantic and western Indian Ocean....
This federal Project Grant award of $433,991.00, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research project to investigate potential anomalies in the carbon storage of the deep Indian Ocean during the last ice age. The researchers at the University of South Florida will study microscopic fossil samples from sediment cores across the Indian Ocean basin to determine if the deep ocean stored substantial amounts of old, sequestered carbon 18,000 years ago. By analyzing the radiocarbon content and grain size of the sediments, the team aims to understand whether changes in deep Indian Ocean carbon dynamics were a significant factor in past climate shifts. This multiyear project, running from October 1, 2025 to September 30, 2028, will provide research opportunities for early career scientists and graduate students, while advancing scientific knowledge about air-sea carbon dioxide exchange and ocean carbon storage on geological timescales.
