Project Grant 2217468

This two-year Project Grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), provides $100,459 to the University of Washington to support collaborative research building a new three-dimensional subsurface framework for the Cascadia Subduction Zone through integrated analysis of data from the 2021 Cascadia Seismic Imaging Experiment (CASIE21). Key products include a regional-scale structural interpretation of offshore Cascadia from seismic images, and select studies analyzing reflectivity, velocity models, and strain, to gain unique insights into the geometry of the plate interface along the margin, variations in incoming plate and upper plate structure as they relate to megathrust rupture segmentation, and how sediment and crust properties influence wedge evolution and segmentation. The funding also supports four graduate students, two postdoctoral researchers, and three early-career scientists.
