This $203,991 project grant from the National Science Foundation Division of Polar Programs' Polar Programs federal grant program (CFDA 47.078) will fund research tracking divergent warming and tree growth patterns at Arctic treeline forests through February 2025. The University of Arizona will leverage existing tree ring data and assess current hypotheses for divergence between temperature variability and growth rates observed in boreal forests since the mid-20th century. Researchers will use...
The University of Arizona was awarded a two-year, $143,148 Project Grant from the National Science Foundation to support the COLLABORATIVE RESEARCH: OPENDENDRO - ADVANCED OPEN-SOURCE TOOLS FOR PALEOENVIRONMENTAL RECONSTRUCTION project. The grant was awarded on June 1, 2021 under the NSF's Geosciences program (CFDA 47.050), which aims to expand fundamental knowledge and understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Through this...
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...
The University of Arizona received a three-year, $639,466 Project Grant award from the National Science Foundation Division of Atmospheric and Geospace Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will support research to develop a millennial-length history of climate variability in the northeast Pacific Ocean region using paleoclimate proxies from growth increments in the marine bivalve Pacific geoduck and tree-ring chronologies. The research aims to reconstruct...
This Project Grant from the National Science Foundation will fund research from September 1, 2021 to October 31, 2022 totaling $110,001. The grant was awarded under the Geosciences program (CFDA 47.050), which supports basic research to strengthen understanding of the integrated Earth system. Specifically, the grant will support research investigating the impacts of hemispheric moisture transport and atmospheric dynamics on millennial-scale Arctic hydroclimate during the Holocene. The grantee,...
The University of Arizona was awarded a two-year, $416,602 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences. The grant falls under the Geosciences program (CFDA 47.050), which supports basic research in the atmospheric, earth, and ocean sciences to strengthen the national scientific enterprise. Specifically, the University will conduct a collaborative research project titled "COLLABORATIVE RESEARCH: P2C2--SUBDECADAL PLEISTOCENE INDIAN...
The University of Arizona was awarded a $280,721 project grant from the National Science Foundation Division of Ocean Sciences on September 1, 2021. The grant is funded through the NSF's Geosciences program (CFDA #47.050), which supports basic research in the atmospheric, earth, and ocean sciences to strengthen the national scientific enterprise. Under this two-year award, the University will unravel southern hemisphere westerly wind variability through the last ~150,000 years using Tasman Sea...
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...
The National Science Foundation awarded a $291,713 Project Grant under its Social, Behavioral, and Economic Sciences (CFDA 47.075) program to the University of Arizona (doing business as the Arizona Board of Regents) to conduct a dendrochronology (tree-ring dating) study. This two-year project aims to establish a new high-resolution chronology for the archaeological record in a region that experienced cultural adaptation and transitions between the 8th and 12th centuries AD due to climate...
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...
