Lecture: Ear to the Ground – Listening into Extraordinary Conversations between the Oceans and the Solid Earth (Prof. Chris Bean, DIAS) – THIS Wednesday 25th October 2017
October 255:30 pm - 8:00 pm
Due to unforeseen circumstances, our lecture on “Graphite: the New Black Gold” (George Reynolds) had to be postponed. We are so lucky to host another talk and many thanks to Professor Chris Bean for stepping in at such notice for this.
Planet Earth is a connected system of physical, chemical and biological interactions. Yet in our minds we tend to divide it into multiple compartments. Two of those compartments are the Oceans and the Solid Earth. With the exception of our weather systems, we usually think of them as separate entities, largely divided from each other. This could not be further from the truth. Even in the centre of continental land masses we can sense the oceans of the world through their distal ground vibrations. It is a long-range conversation. These vibrations hold information about the oceans themselves and through some clever decoding also allow us that keep a continuous health check on the whole planet, especially its volcanoes. In this talk we will explore the origins of the ocean’s ‘voice’ and see how it can be used to monitor our world.
