Turning the Tide - Seabeds and the Future of Security

Zero Pressure

In this special edition of the Zero Pressure podcast, we will be discussing the mapping of the Earth’s oceans. It’s been said that the ocean is the Earth’s final frontier for good reason. With telescopes, scientists can see objects in space that are 30 billion light years away from Earth. Closer to home, 90% of Mars and the entire Moon’s surface has been mapped. Yet only a quarter of Earth’s oceans have been mapped. How can detailed ocean maps be used to solve problems as wide-ranging as energy, defence, and climate change?

We are joined in the studio by Professor Jenny Collier. Jenny is a Professor of Marine Geophysics at Imperial College London with broad interests in geology, geophysics, and geodynamics. She specialises in marine methods and often goes to sea on expeditions to collect data that has transformed our understanding of Earth science, including the process by which the island of Britain became isolated from continental Europe. We will also be hearing recordings of the panellists from a Zero Pressure live event at the Royal Geographical Society, part of the 2023 Great Exhibition Road Festival.

The Zero Pressure podcast series looks at how science and technology positively can contribute to solving complex, interrelated global challenges of today and tomorrow. We look at pioneering technologies and speak to those on the thinking edge.

Zero Pressure is a podcast from Imperial College London and Saab. A relaxed conversation with those on the cutting edge of science and technology - hosted by Britain's first astronaut Helen Sharman - Presented by Imperial College London and Saab.
