This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $118,081 to the Board of Regents of the Nevada System of Higher Education, operating through the University of Nevada, Reno, for a research project titled "Towards a Physics-Based Firn Model: Understanding the Relationship Between Microstructure and Creep". The project aims to develop a comprehensive understanding of the compaction and microstructural evolution of polar firn, the transitional phase between snow and glacial ice, through mechanical testing and microstructural characterization of firn cores from four different locations at Taylor Dome, Antarctica. The research will involve a PhD student and several undergraduates, and the results will be used to improve the community firn model, which is critical for interpreting ice sheet mass balance changes, understanding ice flow rates, and better interpreting ice core paleoclimate records. The award period is from July 1, 2025 to June 30, 2028.
