Planet Visionaries – Ep 19: Deep-ocean discovery with Sheena Talma and Katy Croff Bell

In this episode of Planet Visionaries, a landmark podcast series in partnership with the Rolex Perpetual Planet Initiative, host Alex Honnold speaks with marine biologist Sheena Talma and deep-sea explorer Katy Croff Bell, who are National Geographic Explorers and members of the Rolex and National Geographic Perpetual Planet Ocean Expeditions. Together, they reveal how only 0.001 percent of the deep ocean has been visually observed even though it constitutes two-thirds of the planet. From discovering shipwrecks on the ocean floor to mapping unexplored habitats, this episode reveals why the deep ocean may be humanity’s greatest remaining frontier. For nearly a century, Rolex has supported pioneering explorers. Over time, the company has moved from championing exploration for the sake of discovery to protecting the planet. Through the Perpetual Planet Initiative, Rolex stands alongside the inspiring people who are dedicated to building a better future for all life on Earth.
