This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $419,913 to the University of Utah to investigate the sources of global seismic scattering using advanced array processing and Bayesian inversion techniques. The objective is to analyze compressional (P) waves that pass through the Earth's core-mantle boundary, examining the strength, timing, and angles of pre- and post-cursor signals to map the locations and properties of structures within the Earth that give rise to these scattered seismic waves. The 3-year project, running from August 1, 2025 to July 31, 2028, will apply this advanced statistical approach to a new global dataset to enhance understanding of the Earth's dynamic interior processes and their connection to surface tectonic activity. The findings will provide crucial insights into the Earth's composition and structure.
