In the last few decades, seismologists have mapped the Earth's interior (crust, mantle, and core) in ever increasing detail. Natural earthquakes, the sources of energy used to probe the Earth's inside via seismic computerized tomography, occur mostly on tectonic plate boundaries. Seismometers, the receivers of earthquake wave motion, are located mostly on dry land. Such fundamentally inadequate 'source-receiver' coverage leaves large volumes inside the Earth entirely unexplored. Here be dragons! Placing seismic stations on the ocean bottom is among the solutions practiced successfully today. But there are exciting alternatives. Enter MERMAID: a fully autonomous marine instrument that travels deep below the ocean surface, recording seismic activity (and marine environmental data), and then reporting it by surfacing for satellite data transmission. This presentation will discuss a century of Earth imaging, a decade of instrument design and development, and the challenging – and wet – places that our scientific journey has taken us.
 

Frederik Simons is a geophysicist at Princeton University. Usually from the safety of his office, he analyzes data from digital global seismic networks to study the physical properties of the interior of the solid Earth, and from gravity satellite missions to weigh the ice sheets melting off its surface. To help increase seismic station coverage around the globe, he has been leaving his comfort zone by prototyping floating earthquake recorders in the oceans, and is now promoting the next big push in earth observation through the international initiative "EarthScope-Oceans". Simons joined the Princeton faculty in 2006. He is also an Associated Faculty member in the Program in Applied & Computational Mathematics and serves on the Executive Committee of the Program in Archaeology. Between 2010 and 2013, Simons was the Dusenbury University Preceptor of Geological & Geophysical Sciences. Previously, he was a Lecturer at University College London, a Princeton Council of Science & Technology Beck Fellow and a Department of Geosciences Hess Postdoctoral Fellow. Simons received a Ph.D. in Geophysics from M.I.T. and his M.Sc. in Geology from the KU Leuven in Belgium, of which he is a native.

 


OMSI Science Pub at the Empirical Theater will be a ticketed event beginning on October 17. To guarantee a seat at this event, please buy tickets online or at the OMSI front desk. Advanced tickets will be available for purchase until 2pm on the day of the event. Please show your ticket at the theater entrance upon arrival.

 

If the event sells out, we will update the website and Facebook listings accordingly. If the event does not sell out in advance, attendance will be first-come, first-served at the door and at-the-door admission will remain a suggested donation.

 

There will no longer be official seat reservations available at the door. You are welcome to reserve a seat with your jacket or sweater.


Science Pub OMSI is a monthly event that is open to anyone and everyone – no scientific background required. Just bring your curiosity, sense of humor, and appetite for food, drinks and knowledge! For more information or to sign up for our mailing list, email: sciencepub@omsi.edu.

 

Theory, OMSI's eatery will be open with pizza, salads and ice cream. The Empirical Cafe will be open with sandwiches and snacks. Both locations have alcoholic and non-alcoholic drinks. Food and drink are welcome in the theater. Parking is free for the event. Doors open at 5pm.
