Peter Selkin, Ph.D., Assistant Professor, Environmental Geophysics, UW - Tacoma
Earth’s magnetic field, produced by our planet’s molten outer core, has reversed itself many times throughout Earth’s 4.5 billion-year history. Will the North Magnetic Pole head south again anytime soon? Join UW – Tacoma’s Peter Selkin, Ph.D., to explore what we know about Earth’s magnetic field, its history of reversals, and how we use the geological record to look into the deep Earth.
