It's Hot Down There!
Measuring the Temperature of the Earth's Crust

Research Professor of Earth and Planetary Sciences

Moderated by: Cynthia Wichelman, M.D.

Thermal energy is an important driver of many geological processes, including the generation of molten rocks in the deepest part of the earth's crust, about 30–40 km below the surface. Yet, until recently, temperatures deep inside the earth's crust were uncertain because of the difficulties associated with measuring the thermal conductivity, or how much heat is flowing through the rocks that compose the crust. Using a laser, Professor Hofmeister was able to circumvent the problems that plagued others in the past and has determined that the lower crust is much hotter than previously thought.

Science On Tap is a place where, for the price of a beverage, anyone can come to explore the latest ideas in science and technology. Meetings take place outside a traditional academic context, in the Crown Room at Schlafly Bottleworks.

Meetings are held on the last Wednesday of the month during the academic year, usually from 7:00 - 8:30 PM. The standard format is as follows: 20 minutes of presentation, followed by a 7 minute break for attendees to introduce themselves to each other at the table, and then an hour of discussion. Seating is limited to the first 100 people.  No reservations accepted.
