Project Grant 2508421
- 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...
- This $711,586 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at North Carolina State University to analyze thirty years of foraminiferal assemblages from the Santa Barbara Basin. The grantee will create a record of planktic foraminifera abundances from stored samples collected in the basin and connect the results to modern oceanographic measurements and older seafloor sediments. This will improve understanding of how climate change has...
- The National Science Foundation Division of Ocean Sciences awarded a $561,018 project grant to the University of South Carolina under the Geosciences program (CFDA 47.050) to conduct collaborative research examining three decades of foraminiferal assemblages in the Santa Barbara Basin. Over the three-year period from July 2022 to June 2025, the University will create a thirty-year record of planktic foraminifera abundances from stored samples collected in the Santa Barbara Basin, California....
- 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 (NSF) Project Grant awarded under CFDA 47.050 Geosciences program provides $150,602 to the University of California, Irvine (UCI) to conduct collaborative research on changes in the carbon cycle between the Earth, ocean, and atmosphere over geological timescales. The researchers will use radiocarbon dating of microfossil shells to determine if the deep Indian Ocean stored substantial amounts of carbon during the last ice age, which could have affected past global...
- 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...
- 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...
- The National Science Foundation's (NSF) Division of Ocean Sciences awarded a $335,736 Postdoctoral Fellowship (CFDA 47.050 Geosciences) to the University of California, Santa Cruz (UCSC) to investigate past changes in ocean circulation and ice sheet variability in the early Pleistocene epoch. This project will utilize sediment cores collected from the North Atlantic in 2023 to build a detailed timeline of mean-state changes in the climate system and quantify the nature of ocean circulation...
- 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...
- 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...
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 "BIGMACS" modeling software, which will result in more accurate sedimentation rates and reduced age-model uncertainty. This will broadly improve paleoclimate data compilations used to validate and improve climate models. The project will also support the career development of a postdoctoral researcher, train graduate students, and engage an undergraduate student in interdisciplinary paleoclimate research.
