We sometimes hear that 'we know more about Mars than the deep ocean', but is that true? Exploring the deep ocean is a recent enterprise, made possible by new technology in the past two centuries, but what we now know about the dark depths is as remarkable as the unknowns that remain.

This lecture examines the deep-sea discoveries that have transformed our understanding of our planet, and the history of exploring the deep ocean that covers most of it.

A lecture by Dr Jon Copley, University of Southampton 15 January 2019
