Structure & Dynamics of the Oceanic Lithosphere-Asthenosphere System

How is oceanic lithosphere created and modified? Why is the oceanic asthenosphere weak? How is mantle flow recorded within the lithosphere and asthenosphere? What is the scale and vigor of convection beneath the plates?

Understanding Sub-Lithospheric Small-Scale Convection By Linking Models of Grain Size Evolution, Mantle Convection and Seismic Tomography

Ambient Noise Analyses at Broadband Ocean Bottom Seismometers: Data Quality and Transfer Function Corrections

Broad-band ocean bottom seismometer noise properties

Continental Breakup & Mid-Ocean Ridge Dynamics

How does rifting transition to seafloor spreading? Why and how do continents split apart? What processes control mid-ocean ridge dynamics?

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 …
