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 $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 Project Grant award of $381,740 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project led by George Mason University to disentangle paleoclimate signals from individual foraminiferal analyses across the Paleocene-Eocene Thermal Maximum (PETM) at International Ocean Discovery Program Site U1580. The project aims to remedy known limitations in PETM foraminiferal records by applying cutting-edge analytical techniques to measure...
This $192,832 National Science Foundation Division of Ocean Sciences Project Grant supports research at San Jose State University to generate new paleoceanographic records from the late Miocene to early Pliocene periods in the central Pacific sector of the Southern Ocean. The records will document ocean surface temperature and biological productivity variability to provide insights into the role of the Southern Ocean in late Miocene climate change. Specifically, the grant will fund the...
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 $172,778 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research to test climate model predictions of hydrologic change in the tropical Atlantic during a past warm period. Specifically, the awardee, Utah State University, will geochemically analyze oxygen isotopes and magnesium-to-calcium ratios in planktonic foraminifera from deep-sea sediment cores at several sites, including Ocean Drilling Project Site...
This $106,572 federal Project Grant award from the National Science Foundation's Integrative Activities (CFDA 47.083) program supports research to improve climate reconstructions and quantify the preservation of organic biomarkers in marine sediments. The primary awardee, President and Fellows of Middlebury College, will employ a latitudinal transect of existing sediment cores from the Line Islands region of the equatorial Pacific to investigate how variations in bottom water oxygen conditions...
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 $240,179 project grant to the University of California Santa Cruz under the Geosciences federal grant program (CFDA 47.050) on January 15, 2023. The grant will fund the development of high-resolution paleoceanographic records from the late Miocene to early Pliocene periods (8.3-4.0 million years ago) at the central Pacific sector of the Southern Ocean. Specifically, the project will generate a UK’37-based sea surface...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $387,909 to Lehigh University to conduct collaborative research on tracing Pacific Ocean circulation and ventilation during the warm Pliocene epoch. The primary goals are to: 1) test hypotheses about North Pacific deep-water formation and overturning circulation during the warm Pliocene; 2) trace the regional distribution of ocean ventilation; and 3) refine the use of redox, temperature, and productivity proxies to reconstruct Pliocene North Pacific ocean conditions. The project will generate new paleoceanographic records from sediment cores and analyze climate model simulations to better understand ocean circulation patterns during past warm intervals. This award supports the research and training of five early-career scientists, as well as mentoring of high school and undergraduate students. A sub-award of $244,995.54 to the University of Arizona will focus on generating stable isotopic and trace elemental records from foraminiferal carbonates to investigate Pliocene bottom water temperature and geochemistry.
