Over 65% of the Earth’s surface is covered by water and in some places more than 10km deep! Most of the Earth’s plate building processes operate here: generated heat is dissipated, economic resources are formed, life exists in environments as hostile as the surface of other planets and islands soar to elevations higher than Everest above the surrounding seabed. 

We need to see through the seabed to know what forms the Earth beneath. Now remote sounding is enabling us to see by listening. Professor Christine Peirce will reveal how this is done with equipment deployed from state-of-the-art research vessels and examples drawn from current Discovery Science projects.
