This is a $227,396 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to Colorado State University. The award period runs from August 1, 2024 to July 31, 2026. The project aims to analyze global seismic data over the past four decades to understand, localize, and quantify changes in the global ocean wave climate. Key objectives include advancing the understanding of the long-term observational record of Earth's microseism field, studying the geophysical source processes behind seismic signal generation, and incorporating outreach activities to increase public awareness of the relationship between seismology, geophysics, and ocean wave evolution. The project will deliver a public-facing website displaying near-real-time regional and global microseism metrics to complement existing ocean wave data products. No sub-awards are planned under this grant.
