This Project Grant award, totaling $528,369.00, was provided by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) to Trustees of Dartmouth College. The award, with a start date of July 1, 2025 and an end date of June 30, 2028, supports collaborative research to develop a comprehensive, physics-based model for understanding the densification of polar firn and its impact on ice sheet dynamics. The research aims to characterize the microstructural evolution of firn cores collected from four locations at Taylor Dome, Antarctica with varying accumulation rates. Through mechanical testing, X-ray micro-CT imaging, and electron microscopy, the project will investigate how firn microstructure influences the dominant deformation mechanisms during densification. This data will be used to improve community firn models, which are critical for interpreting ice sheet mass balance changes, ice flow rates, and ice core paleoclimate records. The project will involve a PhD student and several undergraduates.
