Published by the American Geophysical Union as part of the Geodynamics Series, Volume 31.

Geomagnetism, dynamo theory, seismology, geodesy, and mineral physics each present significant perspectives on Earth's core. When interelated, scientists gain and invaluable vantage from which to understans the evolution, dynamics, and state of the core. Earth's Core: Dynamics, Structure, Rotation presents a synthesis of current understanding in proactive analyses of Earth core phenomena, including research in core composition, wave-speed variation, magnetic field signatures, core mantle boundary issues, and more.
