Earth's Core: Geophysics of a Planet's Deepest Interior

Earth’s Core: Geophysics of a Planet’s Deepest Interior provides a multidisciplinary approach to Earth’s core, including seismology, mineral physics, geomagnetism, and geodynamics. The book examines current observations, experiments, and theories; identifies outstanding research questions; and suggests future directions for study.

With topics ranging from the structure of the core-mantle boundary region, to the chemical and physical properties of the core, the workings of the geodynamo, inner core seismology and dynamics, and core formation, this book offers a multidisciplinary perspective on what we know and what we know we have yet to discover. The book begins with the fundamental material and concepts in seismology, mineral physics, geomagnetism, and geodynamics, accessible from a wide range of backgrounds. The book then builds on this foundation to introduce current research, including observations, experiments, and theories. By identifying unsolved problems and promising routes to their solutions, the book is intended to motivate further research, making it a valuable resource both for students entering Earth and planetary sciences and for researchers in a particular subdiscipline who need to broaden their understanding.

• Includes multidisciplinary observations constraining the composition and dynamics of the Earth’s core
• Concisely presents competing theories and arguments on the composition, state, and dynamics of the Earth’s interior
• Provides observational tests of various theories to enhance understanding
• Serves as a valuable resource for researchers in deep earth geophysics, as well as many sub-disciplines, including seismology, geodynamics, geomagnetism, and mineral physics

Vernon F. Cormier is a Professor of Physics and Geophysics at the University of Connecticut. He received a BS from the California Institute of Technology and a PhD from Columbia University. His research has specialized in seismic wave propagation and deep Earth structure. He has served as an editor for the Geophysical Journal International and Physics of the Earth’s Interior. Among services to professional societies he has served the Seismological Society of America as Vice President and the American Geophysical Union as Secretary of the Seismology Section and Chair of the Study of Earth’s Deep Interior (SEDI) focus group.

Michael I. Bergman is the Emily H. Fisher Professor of Physics at Bard College at Simon’s Rock, where he teaches courses ranging from Introduction to Geology to Solid-state Physics to a field course in Volcanology on the island of Montserrrat. He earned a BA from Columbia University and a PhD from MIT. His research has focused on the solidification and deformation of metals, alloys, and aqueous solutions, with applications to Earth’s core and sea ice. He is the recipient of the Doornbos Prize for research on the deep Earth by a beginning investigator, has been the long-standing secretary of SEDI, and has served as guest editor for several journals.

Peter L. Olson is an adjunct professor in the Department of Earth and Planetary Sciences at the University of New Mexico. He earned a BA from the University of Colorado and a PhD from the University of California Berkeley. His research focuses on the dynamics of Earth and other planets. He co-authored a book on convection in planetary mantles and served on editorial boards of numerous scientific journals. He was elected to the American Academy of Arts and Sciences, the US National Academy of Sciences, and received the Petrus Peregrinus Medal from the European Geosciences Union and the Inge Lehmann Medal from the American Geophysical Union.
