The Regents of the University of Idaho was awarded a $156,022 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences under the Geosciences program (CFDA 47.050). The grant will fund a collaborative research project to perform millennial-length, multi-metric reconstructions of paleoclimates in the Greater Yellowstone Ecoregion through July 2026. Researchers will generate quantitative wood anatomy chronologies from two tree species and produce regional...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $185,538 will support a collaborative research project to resolve uncertainty in past delta-14C spikes from tree rings. The project aims to use field and model-based experiments to evaluate how different tree species and latitudes affect the uptake and storage of carbon, which impacts the precision of tree ring records of past solar energetic particle events. The research team, led by Montana State...
This $211,743 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to aid interpretations of past climate and plan for future changes. The primary objectives are to: Use dendrometers to measure how tree growth responds to changes in precipitation frequency, intensity, and timing at sites in the AmeriFlux network. Reconstruct wet extremes of precipitation from previously collected tree-ring...
This $202,212 project grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to resolve uncertainties in past delta-14C spikes observed in tree rings. The primary objectives are to: 1) quantify physiological sources of uncertainty in 14C measurements from tree rings, and 2) improve estimates of the timing, duration, magnitude, and solar phase of past extreme solar energetic particle events. The research team will conduct field- and...
This National Science Foundation (NSF) Project Grant under the Geosciences program (CFDA 47.050) awarded to Brigham Young University will advance the understanding of global paleoclimate through the expansion of African dendrochronology (tree-ring based climate reconstruction). The $103,171 award, effective July 15, 2024 through June 30, 2027, will: Measure radiocarbon, tree ring width, and quantitative wood anatomy from dominant tree species in Zambia to develop multi-century climate records....
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to better interpret past climate and plan for future changes. The total funding amount is $324,677, with an award date of July 1, 2024 and an ultimate completion date of June 30, 2027. The key products and services to be delivered under this grant include: Using dendrometers (instruments that record tree growth in real-time) to...
This National Science Foundation Project Grant of $800,670 will support research to extend tree-ring based reconstructions of Atlantic Gulf Basin hydroclimate over the Common Era. Led by the University of Arizona with completion expected by June 2025, the project aims to collect old-growth bald cypress and longleaf pine samples from trees harvested in the late 19th and early 20th centuries. These extended tree-ring chronologies will be used to develop regional and seasonal hydroclimate...
This $195,606 federal Project Grant award was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050) to The Trustees of Columbia University. The award will support the creation of a "North American Temperature Atlas" (NATA), a gridded reconstruction of warm season surface air temperatures across North America. The project will leverage new and existing tree-ring data from across the continent to analyze the relationships between temperature,...
This National Science Foundation (NSF) project grant under CFDA 47.050 (Geosciences) will advance understanding of global paleoclimate through the expansion of African dendrochronology (tree-ring analysis). The $319,165 award to Indiana State University, with a planned sub-award to Tall Timbers Research, Inc., aims to develop multi-century climate records from tree species in Zambia. The project will use tree ring width, wood anatomy, and radiocarbon measurements to create a gridded...
The National Science Foundation awarded a $542,834 Project Grant to the University of Arizona under the Geosciences program (CFDA 47.050) to conduct collaborative research reconstructing Southern Rocky Mountains warm season temperatures over the past 2,000 years. The research aims to develop a temperature reconstruction using bristlecone pine from the Rio Grande headwaters region, augmented with updated hydroclimate reconstructions, to evaluate long-term regional temperature and hydroclimate...
