Project Grant 2503849
- The National Science Foundation awarded a $391,271 project grant under their Geosciences Program (CFDA 47.050) to the University of Arizona for a collaborative research project titled "Seasonal and Century-Scale Climatic and Ocean Response to Deglacial Mississippi River Outflow due to Laurentide Meltwater." The project aims to improve understanding of how past ice sheet melting and associated freshwater inputs impacted regional climate, ocean circulation, and ecosystems. Researchers...
- This $683,266 Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to reconstruct global ice volume and bottom water temperature over the past 1-3 million years. The project at Brown University will analyze multiple climate proxies, including biomarkers and stable isotopes, using machine learning algorithms to resolve global ice volume and ocean temperature signals. The key objectives are to assess the role of CO2 and ice albedo in global...
- This three-year, $1.2 million Project Grant from the National Science Foundation Division of Earth Sciences aims to test the role of seasonality in abrupt climate change through reconstructing fluctuations of a late-glacial ice mass in eastern North America. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences, the University of Maine will collaborate with researchers to determine the signature of summer warming-driven ice retreat...
- This federal Project Grant award of $355,024 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort to reconstruct the collapse of the Cordilleran Ice Sheet in western Canada since the last ice age. The project aims to determine the timing and rate of the ice sheet's disappearance over the past 10-20 thousand years through geologic dating of rock samples and computer modeling. By improving understanding of past ice sheet changes, the...
- This federal Project Grant award of $370,228, funded by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078), supports collaborative research on the mechanisms of moisture-driven ice growth during the Miocene Climate Optimum, a past period of global warming. The interdisciplinary research team will use advanced Earth system models and geologic data to investigate how increased high-latitude snowfall may have offset Antarctic ice sheet melt during this warmer climate interval....
- This three-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $586,098 to Texas A&M University to conduct research reconstructing ancient ocean temperatures during the Devonian-Mississippian climate transition. The university will test whether tropical ocean temperatures reached extremely high levels of 95-104 degrees Fahrenheit during the time of early animals. It will examine the role of rapid cooling in triggering biotic crises and explore...
- This three-year, $109,644 project grant from the National Science Foundation Division of Earth Sciences aims to advance understanding of abrupt climate change through reconstructing fluctuations of a late-glacial ice mass in eastern North America. Funded under the Geosciences program (CFDA 47.050), the University of Arizona will lead efforts to determine the role of seasonality in abrupt climate shifts by mapping glacial landforms and dating the pattern and timing of recession for an ice cap...
- 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 $261,875 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research study on Antarctic ice margin dynamics at the University of Delaware. The research aims to reconstruct a record of changes in the Antarctic ice sheet over time by analyzing ice rafted debris preserved in ocean sediment cores. The project will leverage sediment core data from an Ocean Drilling Program site in the southern Indian Ocean to investigate...
- This federal Project Grant award from the National Science Foundation's Division of Polar Programs (CFDA 47.078) provides $100,956.00 to The Research Foundation for the State University of New York to conduct collaborative research investigating southern ocean sea surface temperatures and freshening during the late Pliocene and Pleistocene along the Antarctic margin. The objective is to generate multi-proxy paleoclimate records of sea surface temperature and meltwater during deglacial and...
This $275,001 Project Grant award by the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to understand how Earth's climate and oceans responded to the influx of meltwater from the Laurentide Ice Sheet during the last deglaciation, approximately 20,000 to 11,700 years ago. The research will generate high-resolution reconstructions of ocean-atmospheric and biogeochemical variability from marine sediment cores collected offshore Texas, focusing on characterizing the spatial extent, timing, and frequency of freshwater intrusions into the marine environment via the Mississippi River outflow. This work aims to improve understanding of the short- and long-term effects of past ice sheet melt on marine ecosystems, with the goal of helping scientists and the public anticipate potential consequences of modern ice sheet melting and freshwater input. The award supports student research and training, as well as public engagement through data visualizations and educational outreach.
