Depth records in diving. Gaëlle Giesen
<p><strong>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.</p><p><br></p><p>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.</p><p><br></p><p>In this episode, we discuss:</p><p>- Deep Diving: How a background in astrophysics translates to the practical engineering and problem-solving needed for extreme exploration.</p><p>- The Record Breaker: Gaëlle’s experience setting the women's world record for open water rebreather diving (222m) and her subsequent 230m cave dive.</p><p>- Calculated Risk: The mental preparation required for extreme depth, including the difficult process of writing "testaments" and accepting the inherent dangers.</p><p>- 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.</p><p>- 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.</p><p>- What's Next: A glimpse into Gaëlle's upcoming projects and new exploration goals.</p><p><br></p><p>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. </p><p><br></p><p><br></p><p>Connect with Gaëlle:</p><p>Facebook: </strong><a href="https://www.facebook.com/profile.php?id=100095601341531"><strong>https://www.facebook.com/profile.php?id=100095601341531</strong></a><strong></p><p>Instagram: </strong><a href="https://www.instagram.com/gaelle.giesen/"><strong>https://www.instagram.com/gaelle.giesen/</strong></a><strong></p><p>LinkedIn: </strong><a href="https://www.linkedin.com/in/ga%C3%ABlle-giesen-ph-d-a19b456a/"><strong>https://www.linkedin.com/in/ga%C3%ABlle-giesen-ph-d-a19b456a/</strong></a><strong></p><p><br></p><p>If you enjoyed this episode, please follow the show and share it with your dive buddy. </p><p>Changing the culture starts with a conversation. </p><p>Contact me:</strong><a href="mailto:%20info@cenotegirl.com"><strong> info@cenotegirl.com</strong></a><strong></p><p><br></p><p>Don’t forget to subscribe!

Diving with a Robot! Vickie Siegel
<p><strong>In this episode of Tech Diving On Air, host Tamara sits down with Vickie Siegel, a marine technology entrepreneur, cave diver, and co-founder of Sunfish—a company developing highly advanced autonomous underwater vehicles (AUVs).</p><p><br></p><p>Together, they explore the fascinating intersection of cutting-edge robotics and technical diving. Vickie shares the incredible story of how the Sunfish robot was born from a desire to map unexplored underwater caves and has since evolved into a tool capable of navigating some of the planet's most extreme environments—from the depths of Wakulla Springs to the icy waters of Antarctica, and perhaps one day, the oceans of Jupiter's moon, Europa. They discuss the unique challenges of building a robot that can think for itself in a cave, the differences between ROVs and AUVs, and how these machines are not replacing divers, but working alongside them to push the boundaries of exploration.</p><p><br></p><p>In this episode, we discuss:</p><p>- The Birth of Sunfish: How a casual conversation about mapping caves led to the creation of an autonomous, hovering underwater robot.</p><p>- ROVs vs. AUVs: Understanding the difference between a tethered remote-controlled vehicle and a robot that can think and navigate independently.</p><p>- Cave Diving Robots: Why navigating a cave is one of the hardest challenges for an AUV, and how Sunfish uses sonar and spatial AI to find its way.</p><p>- From Florida to Space: The journey from testing in Wakulla Springs to being tasked by NASA to develop technology for exploring extraterrestrial oceans.</p><p>- Robots and Divers as Teammates: How technology like Sunfish can assist human divers in data collection, infrastructure inspection, and reaching depths beyond human limits.</p><p>- The Future of Underwater Exploration: What's next for the Sunfish team, including the development of new "Nova fish" and the ongoing quest for full autonomy.</p><p><br></p><p>You can learn more about Vickie Siegel and her team's work by searching for Sunfish AUV online, or by following their ongoing projects as they continue to explore the underwater world.</p><p><br></p><p><br></p><p>About the Guest: Vickie Siegel is the co-founder of Sunfish. She’s also a badass cave explorer, expedition leader with experience in running complex logistics in extreme environments. </p><p><br></p><p>Connect with Sunfish and Vickie Siegel:</p><p><br></p><p>🗣️JOB OPENING AT SUNFISH </strong><a href="https://www.facebook.com/share/18NfCHdxV5/?"><strong>CLICK HERE</strong></a><strong> 🙌</p><p><br></p><ul><li>Website:</strong><a href="https://sunfishinc.com/"><strong> https://sunfishinc.com/</strong></a><strong></li><li>LinkedIn: </strong><a href="https://www.linkedin.com/company/sunfishinc/posts"><strong>https://www.linkedin.com/company/sunfishinc/posts</strong></a><strong></li><li>Facebook: </strong><a href="https://www.facebook.com/sunfishinc"><strong>https://www.facebook.com/sunfishinc</strong></a><strong></li><li>Instagram: </strong><a href="https://www.instagram.com/sunfish_auv/"><strong>https://www.instagram.com/sunfish_auv/</strong></a><strong></li><li>Email: </strong><a href="mailto:Vsiegel12@gmail.com"><strong>Vsiegel12@gmail.com</strong></a><strong></li><li>Alaska project summary click here!</li></ul><p><br></p><p>If you enjoyed this episode, please follow the show and share it with your dive buddy. </p><p>Changing the culture starts with a conversation. </p><p>Contact me: info@cenotegirl.com</p><p><br></p><p>Don’t forget to subscribe!
