As...
The U.S. Geological Survey (USGS) awarded a $3,500,000 Project Grant under the USGS Research and Data Collection program (CFDA 15.808) to the University of Alaska Fairbanks (UAF) to establish a state-of-the-art radiocarbon dating instrument, known as MICADAS, at the university. The award period is from June 7, 2024 to June 6, 2026. The key objectives are to retrofit a designated laboratory space at UAF to accommodate the MICADAS instrument and make it operational for researchers to leverage this...
This Project Grant award from the National Science Foundation (NSF) Integrative Activities program (CFDA 47.083) will support the University of Nevada, Las Vegas (UNLV) in building radiocarbon infrastructure and capacity for measuring the age of carbohydrates in long-lived trees across the Western U.S. The $229,198 award, granted on January 1, 2025, will fund a fellowship to develop the preparatory infrastructure and technical capacity at UNLV to analyze the age of carbohydrates in ponderosa...
This National Science Foundation (NSF) Social, Behavioral, and Economic Sciences (CFDA 47.075) project grant award of $276,830 provides funding to the University of Arizona to revise the timeline for population history and monumental construction in an archaeological context. The project will systematically redate wood and charcoal samples from archaeological sites using new tree-ring dating and radiocarbon calibration techniques to achieve high-precision, near-annual dating. The scientific...
This Project Grant from the National Science Foundation Division of Earth Sciences totals $345,538 to develop a high-throughput/high-sensitivity, in situ 14C extraction line for use in U.S. earth sciences. Funded under the Geosciences program (CFDA 47.050), the grant will support basic research in atmospheric, earth, and ocean sciences through the expansion of knowledge and understanding of the integrated Earth system. Specifically, the Trustees of Columbia University in New York will receive...
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 (NSF) Division of Behavioral and Cognitive Sciences grant award, under the Social, Behavioral, and Economic Sciences program (CFDA 47.075), provides $221,804 to the University of Arizona's Laboratory of Tree-Ring Research (LTRR) from August 1, 2023 to July 31, 2025. The funding supports the LTRR's dendrochronological research, which utilizes tree-ring analysis to provide highly precise dating and chronology-building for archaeological sites and contexts. This...
This $400,442 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds the acquisition of three new instruments for the scanning electron microscope lab at the Arizona LaserChron Center. The instruments - an energy dispersive spectroscopy detector, an electron backscatter diffraction detector, and a Raman spectroscopic system - will replace outdated systems and provide enhanced chemical and structural analysis capabilities. Approximately 350 faculty members,...
This $809,775 National Science Foundation project grant will fund the acquisition of a next-generation multicollector-inductively coupled plasma mass spectrometer for the University of Arizona. The instrument will be housed at the university's Arizona LaserChron Center, a National Science Foundation-supported facility that supports earth sciences research. It will enable improved accuracy and precision for existing analytical methods, development of new techniques only possible with the proposed...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a 3-year, $499,986 Project Grant to Cornell University to investigate potential intra-annual radiocarbon (14C) offsets and their paleoclimate relevance across three geographic regions - the East Mediterranean-Middle East, Southwest United States, and Southeast United States. The project aims to quantify any growing season-related 14C variations and assess their impacts on radiocarbon age calibration,...
This three-year, $1.28 million project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund the acquisition of a Mini Carbon Dating System (MICADAS) to support multi-millennial, multi-user carbon-14 dating applications at the University of Arizona's Laboratory of Tree-Ring Research (LTRR). The MICADAS instrument and associated sample preparation equipment will maximize throughput of precise, small-sample radiocarbon measurements from tree-rings and other archives. Integrated into LTRR's teaching, outreach, and research programs, this new dating facility will serve an international user community and provide hands-on training opportunities in combined dendrochronological and radiocarbon methods. Key activities include continuing to rebuild portions of the radiocarbon calibration curve using single tree-rings, establishing baselines for past solar variability and space weather, and exploring global and regional carbon cycling through high-resolution proxy records. The accessible new infrastructure aims to advance cross-cutting research while inspiring future scientists.
