Investigating the homogeneous nucleation of Earth’s solid inner core.
Alfred Wilson + Andrew Walker + Christopher J Davies ...
The Earth’s solid inner core is integral to the function of our planet. For example, its growth provides power to the geodynamo which is essential to life on Earth. Despite...

Multidecadal variation of the inner core rotation
Yi Yang + Xiaodong Song
Inner core rotation relative to the mantle is an important but as-of-yet enigmatic component of the core dynamics and core-mantle interactions. The rotation has been postulated...

Can Paleomagnetism Be Used to Distinguish Between Changes in Core Structure and Mantle Convection?
Chloe Ritchie + Andrew John Biggin + Christopher J Davies ...
The present-day geodynamo, generating Earth's magnetic field, is believed to be driven by the growth of the solid inner core due to the release of light elements and latent...

The Depth Dependence of Seismic Scattering in the Inner Core.
Ravi Wickramathilake + Vernon F Cormier
The high frequency coda following the P wave reflected from the inner core boundary (PKiKP) can be explained by scattering from 1-10 km scale heterogeneities in the uppermost...
Fall Meeting 2022 | 14 December 2022
An initial map of fine-scale heterogeneity in the Earth’s inner core
Wei Wang + John Emilio Vidale
The seismological properties of Earth’s inner core are key to understanding its composition, dynamics and growth history. Within the inner core, fine-scale heterogeneity has...
