DeepSummary
Nicole Yamase, a marine biologist from Micronesia, and Victor Vescovo, an explorer, had the opportunity to visit the deepest part of the ocean, the Challenger Deep in the Mariana Trench. They descended to a depth of 6.8 miles in a submersible called the Limiting Factor, making Nicole the first Micronesian person to visit this remote location. Nicole was excited to collect sediment samples from the bottom to study the potential connection between shallow marine plants and the deep ocean ecosystem.
The episode also highlights the work of Marie Tharp, a pioneering scientist who mapped the seafloor and discovered the Mid-Atlantic Ridge, providing evidence for the then-controversial theory of continental drift. Despite facing dismissal and gender discrimination, Tharp's groundbreaking work revolutionized our understanding of how the Earth's tectonic plates move and shape the planet.
Currently, only 20% of the seafloor is mapped, leaving vast unexplored areas that could hold significant discoveries about the Earth's geology, ocean currents, climate, and potential new species. Scientists like Vicky Ferrini at Columbia University are optimistic that advanced mapping technologies will allow the complete mapping of the seafloor within our lifetimes, revealing the mysteries of this largely unknown realm.

Top Episodes Quotes
- “Continental drift had been rebuffed for 40 years or more violently rebuffed. You could get fired from believing it.“ by Marie Tharp
- “How could you not be excited about it? You know, people have this passion and enthusiasm for outer space, which is totally understandable, but the ocean is equally, if not more exciting to, because it's here. It's the same planet that we're on. It's equally difficult to get to and to explore, and there's infinite mysteries to be revealed.“ by Vicky Ferrini
- “I was just freaking out. But in that moment, I was just like, holy moly.“ by Nicole Yamase
