The current understanding of the Earth’s deep interior is limited to recent time where we have direct observations from geophysical data. Fortunately, one source exists that records ancient signals from the deep interior, and that is paleomagnetic data. Variations in the magnetic field occur on a broad range of timescales. This presentation gives an overview of recent advances on this topic, including the characterization of long-term trends in paleomagnetic data, the assessment of “Earth-like” numerical geodynamo simulations, and other multidisciplinary approaches that are helping to clarify how paleomagnetic data can be used to understand the evolution of Earth’s deep interior.

Dr. Anat Shahar (Carnegie Institution for Science)
Why is Earth habitable? Where will life be detected elsewhere? What type of planet is most likely to sustain life? Beyond Earth, what are the characteristics of a habitable planet?
This talk will present more questions than answers but will show you how we at Carnegie, along with our international collaborators, are tackling these questions in order to understand the origin of habitable planets.
