This $416,328 Project Grant award from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) supports a collaborative research project to develop two 1,000-year long records of temperature variability and extremes in North Asia using wood anatomical traits from Siberian larch and pine trees. The goal is to assess the relationship between volcanic eruptions and cold conditions, as well as characterize longer-term temperature variability in this climate-sensitive region. The...
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 $372,663 project grant from the National Science Foundation's Division of Integrative Organismal Systems will fund research into drought and cold resistance of northeastern US tree species. The grant is part of the Biological Sciences program (CFDA 47.074), which supports basic biological research to strengthen the nation's scientific enterprise and enhance understanding of major problems. Specifically, the grant will fund extensive field measurements and a manipulative experiment to...
This $136,629 Project Grant was awarded by the National Science Foundation's Division of Polar Programs (CFDA 47.078 Polar Programs) to the University of Massachusetts Amherst. The purpose of the grant is to conduct collaborative research to constrain and understand regional modes of variability in the Atlantic Arctic using ultra-high-resolution climate proxies such as tree rings, lake/ocean sediments, and ice cores. The key products and services to be delivered under this grant include:...
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...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $552,562 Project Grant to Columbia University under the Geosciences federal grant program (CFDA 47.050) for the period of July 15, 2021 through June 30, 2024. The grant supports collaborative research between Columbia University researchers and the Natural Environment Research Council in the United Kingdom to enhance understanding of trans-hemispheric climate variability through analysis of a novel...
This $383,639 National Science Foundation project grant through the Polar Programs federal grant program (CFDA 47.078) will fund research tracking divergent warming and tree growth patterns in Arctic treeline forests of northern North America. The three-year award made to Columbia University on March 1, 2022 will leverage a large tree-ring data compilation and statistical/modeling techniques to assess current hypotheses for divergence between temperature variability and tree growth rates detected since the mid-20th century. Specifically, the grantee will detect recent changes in growth parameters across key Alaskan and northwestern Canadian sites showing unusual growth declines despite warming, using integrated statistical, wood anatomy, and growth modeling methods. Broader impacts include quantitative climate/growth estimates yielding data for modeling environmental change and productivity impacts in northern forests. The award also includes three years of graduate student support and fieldwork-based learning opportunities in Arctic research for educators.
