Planet Visionaries – Ep 18: The Hidden Ocean With Andrew Thurber and Allison Fong

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 Andrew Thurber and microbial oceanographer Allison Fong, who are National Geographic Explorers and key members of the Rolex and National Geographic Perpetual Planet Ocean Expeditions. Thurber studies how deep-sea microbes regulate carbon and methane, while Fong explores how polar microbes underpin fragile ecosystems. Together they reveal how microscopic life quietly shapes the stability of our planet. For nearly a century, Rolex has supported pioneering explorers.
