Broad-band ocean bottom seismometer noise properties

Rayleigh Wave Attenuation and Amplification Measured at Ocean-Bottom Seismometer Arrays using Helmholtz Tomography

Seismological evidence for girdled olivine lattice-preferred orientation in oceanic lithosphere and implications for mantle deformation processes during seafloor spreading

Seismic anisotropy produced by aligned olivine in oceanic lithosphere offers a window into mid-ocean ridge dynamics. Yet, interpreting anisotropy in the context of grain-scale deformation processes and strain observed in laboratory experiments and …

Sub-Lithospheric Small-Scale Convection Tomographically Imaged Beneath the Pacific Plate

Lithosphere structure and seismic anisotropy offshore eastern North America: Implications for continental breakup and ultra-slow spreading dynamics

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 OBS Research into Convecting Asthenosphere (ORCA) Experiment

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 …
