This presentation will outline the rationale and specific aims of the new DEEP group to be formed at Liverpool using funding from The Leverhulme Trust and NERC. Records of ancient magnetic field behaviour provide a time-dependent signal from an outer core process that is widely expected to be sensitive to changing conditions within the lowermost mantle and at Earth’s centre. They are thus uniquely equipped to inform us about the evolution of the deep Earth through time although it is suggested that this potential largely remains to be realised. This presentation will reflect on the state-of-the-art of palaeo-geomagnetic records on timescales of millions to billions of years, the various hypotheses presented to link the variations observed within them to mantle convection and inner core growth, and the work that will be done to test and develop these ideas further.
