This $266,168 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to investigate the geological history and evolution of the Mackenzie River system in the North American Arctic. The primary objectives are to 1) decipher the sedimentary provenance history of the Beaufort-Mackenzie Basin through detrital zircon analysis, and 2) establish a chronostratigraphic framework using strontium isotopes to...
The National Science Foundation awarded a $174,000 project grant to support research examining the impact of varying sediment supply on Arctic delta-front transport processes. Funded under the Geosciences program (CFDA 47.050), the award will support research from April 2021 to March 2023 exploring fundamental knowledge and increased understanding of the integrated Earth system through basic research in the atmospheric, earth, and ocean sciences. Specifically, the grant will fund analysis of how...
The National Science Foundation awarded a $180,000 Project Grant under the Geosciences program (CFDA 47.050) to Dr. Marion McKenzie of Colorado School of Mines. The two-year award beginning September 2023 will support pairing onshore and offshore observations to better understand the dynamics of the Cordilleran Ice Sheet during the last deglaciation approximately 20,000 years ago. Dr. McKenzie will leverage sedimentology, geochronology, geophysics, and glaciology techniques to constrain the...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $349,754 to Montana State University (MSU) to quantify how century to millennial-scale hillslope geomorphic processes influence the storage of ice and carbon in Arctic permafrost soils. The research aims to shed light on fundamental geological processes that control the resilience and vulnerability of ground-ice and carbon in permafrost landscapes, which is critical for understanding future...
This $150,388 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund collaborative research to reconstruct the missing geological record of late Proterozoic tectonism along the western margin of Laurentia using deep-time thermochronology. Three early-career researchers and twelve students from multiple universities will investigate ancient supercontinent breakup using geochemical signatures from rock heating and cooling during deposition and erosion....
The National Science Foundation awarded Macalester College a $116,859 project grant under the Geosciences program (CFDA 47.050) for the period of January 1, 2022 through December 31, 2026. The grant supports collaborative research examining the interactions of natural and social systems with climate change, globalization, and infrastructure development in the Arctic. The Geosciences program seeks to strengthen understanding of the integrated Earth system through basic research in atmospheric,...
This $217,224 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund a collaborative research project studying the Lake Superior basin landscape evolution. Led by President and Fellows of Harvard College, the research team will conduct multidisciplinary studies to better understand ongoing uplift, tilting, and surface processes reshaping the basin. Specific activities include reconstructing the geological past's impact on current landscape changes, mapping...
This National Science Foundation Project Grant of $236,141 supports research by Columbia University under the Geosciences program (CFDA 47.050) from May 15, 2022 to April 30, 2025. The research aims to reconstruct the missing geological record of late Proterozoic tectonism along the western margin of Laurentia using low-temperature thermochronology. Researchers will study the thermal imprint of sedimentary cover on basement rocks beneath major unconformities to fill a one-billion-year gap in the...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) to Purdue University will provide $256,352 from Sep 1, 2024 to Aug 31, 2027 to conduct a continental-scale study of Jurassic-Cretaceous basins and mélange belts along the North American Cordillera. The research aims to test competing models for the Mesozoic development of the western Cordillera and its implications for subduction polarity. Key activities will include analyzing the age, provenance,...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $499,709 to the University of Oklahoma to conduct collaborative research linking fold-thrust belt activity in the Canadian Rocky Mountains to the response in the adjacent Alberta foreland basin. The research team will apply novel methodologies, including low-temperature thermochronology and thermokinematic modeling, to constrain the timing and magnitude of shortening within the...

This Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) provides $262,380 to Clemson University to investigate the geological history and evolution of the Mackenzie River system in the North American Arctic. The key objectives are to:

  1. Decipher the sedimentary provenance history of the Beaufort-Mackenzie Basin through detrital zircon U-Pb and Nd-isotope analysis to understand changes in sediment and freshwater fluxes to the Beaufort Sea over the last 25 million years.

  2. Establish a chronostratigraphic framework for the sedimentary succession using Sr-isotopes to constrain the timing of provenance changes and evaluate potential forcing mechanisms.

This research will provide insights into how high-latitude North American river systems have responded to past climate and tectonic changes, which can inform future climate models. The award period is from Sep 1, 2024 to Aug 31, 2027, and no sub-awards are planned.
