Project Grant 2303577
- This $293,010 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research at The Ohio State University to develop novel isotope proxies that improve understanding of Earth's climate and carbon cycle dynamics at the onset of the Late Paleozoic Ice Age from 350 to 290 million years ago. The grantee will pair calcium and clumped isotope systems to test hypotheses regarding diagenetic influences on stable carbon isotopes used as proxies for carbon...
- The National Science Foundation (NSF) awarded a $192,386 Project Grant through its Geosciences program (CFDA 47.050) to the University of Arizona for a 3-year collaborative research project to reconstruct tropical rainfall patterns over the last 200 years. The project aims to use stable oxygen isotopes measured in tree ring cellulose from sites across Central and South America to study variations in the position and width of the Intertropical Convergence Zone and understand how these changes...
- The Regents of the University of Minnesota received a $142,947 Project Grant award from the National Science Foundation Division of Earth Sciences on July 15, 2021 to support research investigating inter-hemispheric phasing of tropical Andean hydroclimate in response to Holocene orbital forcing. The grant will fund a collaborative research project through June 30, 2024 examining how changes in the Earth's orbit and axis have impacted tropical South American climate over the past 12,000 years....
- The National Science Foundation (NSF) Division of Polar Programs awarded a $532,387 Project Grant to Oregon State University to investigate past atmospheric methane variability using stable isotopes in Antarctic ice cores. The research project aims to develop new laboratory methods for measuring hydrogen isotopes in methane and use the chemical composition of methane to understand changes in atmospheric methane levels during past climate transitions, including periods when the climate was as...
- 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 $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 Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), provides $486,913 to the University of Washington for collaborative research investigating glacial-interglacial variability in tropospheric reactive halogens. Specifically, the research will examine how blowing snow on sea ice can explain increases in sodium ions observed in Greenland and Antarctic ice cores over glacial-interglacial timescales. It...
- This National Science Foundation Project Grant of $529,842 supports the development of a new ice core proxy technique to reconstruct past melt in Arctic ice cores and apply the technique to study past warm periods. The award was made under the Polar Programs federal grant program (CFDA 47.078) to Oregon State University on February 1, 2022 for completion by January 31, 2025. Specifically, the grantee will develop a new method using the xenon/nitrogen ratio to reconstruct surface melt intensity...
- This three-year, $511,918 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research to develop a new framework for advancing climate model representations of cloud and convective processes. The grantee, Columbia University, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate data assimilation will...
- This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $796,213 to The Regents of the University of California, doing business as the University of California, Berkeley, to assess and understand the sensitivity of tropical orographic precipitation to climate variations. The research aims to further develop the theory of tropical orographic precipitation and investigate its response to environmental factors like wind speed, temperature, and...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $892,703 Project Grant to The Ohio State University to develop a framework using modeling approaches to interpret climate variability from ice core delta oxygen-18 in low-latitude and tropical glaciers. The researchers will examine water isotopes in surface precipitation and throughout the atmospheric column in the tropical Andes and northwestern Tibetan Plateau regions. The goal is to improve understanding of how to interpret climate variability, such as temperature and precipitation, from ice core oxygen-18 records in these mid-latitude and tropical mountain glacier locations. This 3-year grant, awarded on September 1, 2023, supports a post-doctoral scholar, doctoral student, and outreach activities through the Byrd Polar Climate Research Center.
