The National Science Foundation (NSF) awarded a $367,031 Project Grant under the Geosciences program (CFDA 47.050) to The Trustees of Columbia University in the City of New York to conduct collaborative research on the microscopic processes that control frictional interfaces in both earthquake faults and ice sheet systems. The goal is to directly observe the coupled processes that govern nucleation, slip, healing, and melting at these interfaces using a custom cryogenic biaxial apparatus and ice samples. The results will be analyzed using machine learning techniques to improve understanding of the mechanics that drive stick-slip cycles and stability in these critical natural systems. This 3-year project will support a graduate student and involve collaboration across three institutions.
