The breakup of supercontinent Pangea occurred ∼200 Ma forming the Eastern North American Margin (ENAM). Yet, the precise timing and mechanics of breakup and onset of seafloor spreading remain poorly constrained. We investigate the relict lithosphere …
The Pacific ocean‐bottom seismometer (OBS) Research into Convecting Asthenosphere (ORCA) experiment deployed two 30‐station seismic arrays between 2018 and 2020——a US contribution to the international PacificArray project. The “Young ORCA” array …
What can seismic noise reveal about how the cryosphere and hydrosphere interact with the solid Earth? How does near-surface structure impact intensity of seismic shaking?
