Hunting the Earth’s Magnetic Field

Professor Lisa Tauxe

The Earth’s magnetic field changes over time and has dropped in strength by over eight percent over the last 100 years. We have magnetic observatory measurements of field strength for only the last 150 years or so, and to understand the long-term behavior of the field we must rely on “accidental” records from archaeological and geological material. Collaboration with archaeologists in the Levant and elsewhere has led to a detailed record of what the field has done since the Iron Age and has produced some startling conclusions about how high the field can get and how fast it can change.

Instructor: Lisa Tauxe is a Distinguished Professor of Geophysics at the Scripps Institution of Oceanography. Her research is on the magnetism of geological and archaeological materials, which she uses to solve a variety of geological and geophysical problems. Tauxe has been elected a member of the American Academy of the Arts and Sciences and the National Academy of Sciences. She has PhD in geology from Columbia University.
