Contents:
Preface -- On the history of inner core discovery -- Seismological tools to study the inner core -- Inner core surface and its interior -- Inner core anisotropy -- Inner core rotational dynamics -- The limitations, the obstacles, and the way forward -- Appendix A. Transmission/reflection coefficients for the flat inner core boundary -- Appendix B. The angle between PKIKP waves and the rotation axis of the Earth -- Appendix C. P-wave velocity in a transversely isotropic inner core -- Appendix D. Transdimensional Bayesian inversion.
Summary: "The inner core is a planet within a planet: a hot sphere with a mass of 100 quintillion tons of iron and nickel that lies more than 5000 km beneath our feet. It plays a crucial role in driving outer core fluid motion and the geodynamo, which generates the Earth's magnetic field. Our understanding of the structure and dynamics of the inner core has improved enormously over the past few decades due to advances in observational seismology. This book is the first to provide a comprehensive review of past and contemporary research on the Earth's inner core from a seismological perspective. Chapters cover the collection, processing, and interpretation of seismological data, as well as our current knowledge of the structure, anisotropy, attenuation, rotational dynamics, and boundary of the inner core. The final chapter suggests new seismological techniques and future avenues of research to address the remaining questions in this field. Reviewing the latest research and presenting a detailed account of how seismology is used as a tool to investigate the inner core, including basic theoretical concepts for those not already familiar with observational seismology, this is an essential resource for both seismologists and non-seismologists interested in this fascinating field of research. With electronic supplements, including inner core-sensitive datasets and 3D visualisations, it will also form a useful resource for courses in seismology and deep Earth processes."--Page 4 of cover.
