3. Oliver Steeds reveals how much we really know about our oceans

How much of our own planet have we truly explored?In this episode of The Future of Exploration, ocean explorer and Nekton Mission Director Oliver Steeds challenges one of our biggest assumptions that the final frontier lies in space. Instead, he argues that the greatest unknown is much closer to home, in the vast, largely unexplored depths of our oceans.Oliver reveals why we have mapped only a fraction of the seabed, why most marine species remain undiscovered, and how these hidden ecosystems play a critical role in regulating the Earth’s climate and sustaining global food systems. From extraordinary deep-sea discoveries to AI-powered species identification, he explores how new technologies and global collaboration are transforming our ability to understand life beneath the waves.If we have discovered less than 10% of ocean life, what might still be out there, and can we find it before it disappears?
