Abstract:
Discovered two years after Pluto, Earth's inner core is the most remote and extreme region of our planet. Consequently, its physical structures are not yet well constrained or understood. However, the effects of the inner core can be observed at Earth's surface; for example, the solidification of the inner core helps to generate our magnetic field. I will introduce the seismological techniques used to observe the inner core, discuss its seismic properties and their possible origins, and present new research examining the surface of the inner core.
