This National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) totaling $322,038 will support research to generate temperature, precipitation and vegetation records spanning the past 13,600 years from Lake Issyk-Kul in Kyrgyzstan. The University of Massachusetts Amherst will conduct a multi-proxy organic geochemical study of the lake's sediment cores to test hypotheses about past climate variability in arid Central Asia. Specifically, the awardee will produce...
This Project Grant from the National Science Foundation's (NSF) Polar Programs will support collaborative research on boreal forest fire feedbacks from 2023 to 2027. The $138,467 award to the University of Colorado Denver will explore the paleohistory of short interval fires in boreal forests through analysis of lake sediment cores. Fieldwork will determine the resilience of current landscapes to short interval fires and whether these are creating novel forest structures. High-performance...
This $248,000 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support a collaborative research project to investigate past Arctic sea ice coverage and its impacts on marine ecosystems. The research team at the University of Massachusetts Boston will analyze ocean sediment cores to reconstruct Arctic sea ice extent and ocean conditions over the past 150,000 years, focusing on the Holocene Thermal Maximum and Last Interglacial warm periods....
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 $343,332 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research at the University of Washington to study the impact of increasing boreal forest fires on the Arctic climate and sea ice. The research aims to: Examine how the increased transport of smoke and black carbon from boreal forest fires to the Arctic affects the region's climate and sea ice through warming and cooling effects. This will involve running climate model simulations...
This Project Grant award, valued at $359,487, was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to The Trustees of Princeton University. The funding will be used to develop advanced analytical methods for high-resolution chemical imaging and dating of ancient ice cores from Antarctica's Blue Ice Areas, which contain climate records spanning over 1 million years. Specifically, the project will utilize cryo-cell laser ablation inductively coupled plasma mass...
This Project Grant awarded by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050) provides $416,328 to William Paterson University of New Jersey to develop two 1000-year long records of temperature variability and extremes in North Asia using wood anatomical traits. The goal is to use quantitative wood anatomy and anomalies like blue rings and frost rings to capture sub-annual and ephemeral temperature conditions that annual tree ring data cannot, in order to assess...
This Project Grant award from the National Science Foundation Division of Polar Programs provides $499,526 to fund a collaborative research project examining how changes in vegetation composition may impact climate-driven wildfire growth in the boreal forests of Northwestern North America. The three-year award runs from November 1, 2021 through October 31, 2024. The Cary Institute of Ecosystem Studies, Inc. will lead the research effort to strengthen understanding of polar regions, as called for...
This $1,237,840 federal Project Grant award from the National Science Foundation Division of Polar Programs, under CFDA Program 47.078, will fund research by the University of Colorado to quantify climate variability and extremes over the past 100,000 years. The research team will use high-resolution measurements from ancient polar ice cores to statistically analyze changes in climate variability and the frequency of extreme events as the Earth's average climate has fluctuated over...
The University of Alaska Fairbanks was awarded a $1.7 million project grant from the National Science Foundation Division of Polar Programs to conduct research titled "Submarine Basins, Steppe, and Sea Ice: Paleoclimate and Paleoecology of the Late Pleistocene and Holocene Bering Sea Shelf" from August 2021 through July 2024. The research funded under this award will investigate the paleoclimate and paleoecology of the Bering Sea shelf through the late Pleistocene and Holocene...
This $380,132 project grant from the National Science Foundation's (NSF) Polar Programs will fund research to generate a new 8.4-million-year paleoclimate record from a drillcore in Lake Baikal, Russia. Specifically, the University of California Santa Cruz will analyze plant-wax hydrogen isotopes and branched glycerol dialkyl glycerol tetraethers from core samples to develop temperature and precipitation proxy records over time. Polycyclic aromatic hydrocarbons and charcoal will also be measured to reconstruct regional wildfire patterns under varying climate conditions. Comparing the results to climate model predictions will test hypotheses about warmer periods' impacts on Siberian climate, vegetation, and wildfires. The project aligns with NSF Polar Programs' mission to strengthen polar research by expanding knowledge of these regions. The award period is July 1, 2022 through June 30, 2025.
