Project Grant 2508422
- The National Science Foundation (NSF) awarded a $308,843 Project Grant under the Geosciences program (CFDA 47.050) to the University of California, Santa Barbara (UCSB) for the project "Collaborative Research: Reconstructing Ocean Sedimentation Rate Variability to Improve Age Estimates for Paleoclimate Data." This project aims to improve the accuracy of sediment age models by compiling radiometric ages from over 250 marine sediment cores. The new data will be used to enhance the...
- 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 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 National Science Foundation Project Grant award of $1,086,964 provides funding to Brown University from July 1, 2022 through June 30, 2025 to develop improved reconstructions of global temperatures during the Miocene climate transition approximately 14 million years ago. The award is made under the Geosciences program (CFDA 47.050) to strengthen understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences. Specifically, the university...
- 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 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,...
- This $359,809 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort between a U.S. modeling expert and a Swiss geochemistry expert to reconcile climate models and proxy data interpretations for the Miocene period (23-5 million years ago), a time of much warmer global temperatures and higher greenhouse gas levels. The project aims to develop novel proxy system models to better understand how paleoclimate proxies...
- The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $599,974 Project Grant to the University of Washington on Aug 1, 2025. This 5-year grant, titled "CAREER: BACK TO THE BEGINNING - REFINING MARINE RADIOCARBON AS A TRACER OF OCEAN CIRCULATION AND TIME IN THE NORTH PACIFIC", will support research to reconstruct ocean ventilation variability from marine sediment cores in the Northeast Pacific over the past 23,000 years. The research aims to address gaps in the...
- The National Science Foundation (NSF) Division of Ocean Sciences awarded a $323,234 Project Grant to Claremont McKenna College under the Geosciences program (CFDA 47.050) for the period of January 1, 2024 to December 31, 2026. The project, titled "MCA PILOT PUI: PROXY-MODEL COMPARISON USING CARBON ISOTOPES FROM ANNUALLY BANDED MARINE CALCIFIERS AND OCEAN CIRCULATION INVERSE MODELS TO EVALUATE COASTAL CARBON CYCLE PROCESSES," will use data from proxy archives to perform a model-proxy...
- This $163,928 Project Grant award 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, and how changes in deep ocean circulation and carbon storage may have impacted global climate. The research team at the University of Washington will analyze microfossils in sediment cores to determine if the radiocarbon content of the deep Indian...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) project grant award to Brown University aims to improve the accuracy of sediment age models used in paleoclimate research. The $185,618 award, effective from September 1, 2025 to August 31, 2027, will compile over 250 marine sediment core radiometric ages to enhance the constraints on the new "BigMACS" age modeling software. This will lead to more accurate sedimentation rate estimates and reduced age-model uncertainty, broadly improving the quality of paleoclimate data compilations. The project will also support the career development of a postdoctoral researcher, train graduate students in interdisciplinary paleoclimate studies, and engage an undergraduate in research. The improved sediment age models are crucial for validating climate models and understanding natural climate variability, which is essential for assessing the effectiveness of climate change mitigation strategies.
