Speakers: Professor Richard Holme

The Earth’s core is located over 2,000km below Earth’s surface, and consists predominantly of molten iron. The region supports fluid motions which generate the geomagnetic field through dynamo action. Such motions can be investigated by a number of geophysical probes, particularly variations in the magnetic field (so-called secular variation) and also the rotation rate of the Earth. In this talk, I present recent work which argues that both of these signals show evidence of large-scale wave motion, and that this motion provides a powerful probe of the structure and dynamics of Earth’s deep interior.
