The Geodynamo: A Unique Window Into the Dynamics of Earth's Deep Interior

November 8, 2018
Neighborhood Lecture Series
Dr. Peter Driscoll

Earth's magnetic field is generated by convective motion in the liquid iron outer core, commonly referred to as the geodynamo. The magnetic field has been protecting Earth from harmful charged particles for at least the last 2.5 billion years, and possibly longer. In this talk, Dr. Peter Driscoll willdiscuss the physical mechanisms that produce the geomagnetic field, conduct a brief survey of planetary magnetism, and explore Earth’s rich paleomagnetic history preserved in ancient rocks, including polarity reversals, superchrons, paleointensity, and the impact of the solidification of the inner core. He will highlight the pioneering contributions made by the Department of Terrestrial Magnetism on early studies of geomagnetism.

Earth is a water world. More than 70 percent of Earth’s surface is covered in water, and the presence of water allowed the emergence of life on our planet and has sustained it for billions of years. But where did Earth’s water come from? Why is our planet apparently so wet and other planets so dry? Water is not only on the outside of our planet, but there may be oceans of water on the inside as well. How much water is inside and how does it get there and get back out again? What is the role of earth’s interior in regulating water at the surface? We will investigate these questions as we probe the depths of our deep blue planet.
