She Dove Inside an Antarctic Iceberg. Most of Her Team Didn't Come Back.

Jill Heinerth dived inside the B-15 iceberg in Antarctica, the largest iceberg ever recorded, roughly the size of Jamaica, in 2001. She was the first human being ever to cave dive inside an iceberg. She nearly didn't come out. In this episode, Pete Bell sits down with Jill Heinerth, one of the world's most accomplished underwater explorers and the first Explorer-in-Residence of the Royal Canadian Geographical Society, to discuss a life lived at the absolute frontier of human endurance. Jill talks about the 2001 iceberg expedition, the Tham Luang cave rescue, and what it means to work in a field where more people have died than have summited Everest. This conversation goes far deeper than adventure stories. Jill is remarkably candid about fear, not the absence of it, but learning to use it, and about the specific psychological and physical demands of operating in environments where a single mistake ends your life. She talks about facing sexism, imposter syndrome, PTSD, and grief as constant companions in her career; about the Mayan civilisation cave systems her team discovered; and about how breathing itself becomes the central skill of her life, underwater and above it. Jill's book Into The Planet was praised by the Wall Street Journal, Oprah Magazine, and the New York Times — and this conversation captures exactly why.
