Federal Grant Award Summary

The University of Colorado at Boulder received a $414,127 Project Grant from the National Science Foundation's Division of Earth Sciences (Geosciences program, CFDA 47.050) awarded on April 15, 2026, with a completion date of March 31, 2029. This research project will develop integrated computational models examining the interactions between glacial isostatic adjustment (GIA) and plate tectonic processes. The primary deliverables include a unified mantle viscosity model consistent with observations of sea level change, crustal motion, gravity anomalies, and geoid structures above subduction zones; mantle convection and GIA models predicting present-day geoid configuration, slab structures, relative sea level, and crustal motions; and analyses of GIA effects on plate motions at mid-ocean ridges and across the San Andreas Fault system.

The project will advance understanding of how past glacial cycles and ongoing deglaciation processes influence earthquake hazards and volcanic activity, with particular focus on the San Andreas Fault and Icelandic volcanism. Research outputs will include peer-reviewed scientific findings, computational models, and datasets that enhance the scientific community's understanding of Earth hazards and long-term geodynamic processes. Additionally, the project supports workforce development objectives through training of future scientists and promotion of advanced computing capabilities within geoscience research.
