In this episode of Tech Diving On Air, host Tamara sits down with Gaëlle Giesen, a Swiss physicist, engineer, and deep-diving explorer whose work bridges the gap between science and extreme underwater environments.


Together, they dive into the rigorous preparation and mindset required to execute world-record-setting cave dives. Gaëlle shares her unique perspective on the intersection of physics and diving, explaining how her scientific background informs her approach to risk management and problem-solving at depths exceeding 200 meters. From the emotional toll of writing "goodbye" letters before a major dive to the controversial topic of establishing rules and regulations within the deep-diving community, Gaëlle offers a candid and thought-provoking look at the realities of pushing human limits underwater.


In this episode, we discuss:

- Deep Diving: How a background in astrophysics translates to the practical engineering and problem-solving needed for extreme exploration.

- The Record Breaker: Gaëlle’s experience setting the women's world record for open water rebreather diving (222m) and her subsequent 230m cave dive.

- Calculated Risk: The mental preparation required for extreme depth, including the difficult process of writing "testaments" and accepting the inherent dangers.

- The Ethics of Exploration: A candid discussion on the lack of official governing bodies for deep diving records, the potential need for standardized rules, and the balance between personal freedom and safety.

- Finding Your Team: Why the success of a deep dive relies entirely on the trust and capability of the support team, and how to build a crew you can rely on.

- What's Next: A glimpse into Gaëlle's upcoming projects and new exploration goals.


About the Guest: Gaëlle is a French deep diver, skydiving champion and scientist who was Tamara’s student in Mexico when she learned Sidemount. Gäelle works for CNES, the space agency in France, and has been mentored by a community of deep divers who she has learned and trained with to achieve what no other woman had done before.
