Christine West

Christine is a polar expedition diver, naturalist, conservation photographer and videographer. She is an Explorer’s Club Fellow who has worked as a professional diver for 18 years dedicated to ocean education, exploration and safety. Christine now spends over six months per year in the field documenting stories about places that are rarely seen and yet are rapidly changing due to the warming of the Earth such as the High Canadian Arctic and Antarctica. Christine uses a variety of tools such as underwater cameras, drones and ROVs to create imagery that serve as voices for ecosystems that need immediate protection. It is important to her to not only document species presence and abundance, but to share their stories and behaviors in a memorable way that drives wider audiences, including inland communities, to care about places that may not be in their backyard but to which they influence and are connected. Christine’s passion to share the lesser-known stories continually pushes her to dive the coldest, sometimes murkiest, most remote areas on the planet.

Darcy Kieran

“Even if you’re on the right track, you’ll get run over if you just sit there.” ~Will Rogers
Darcy has been a Course Director and scuba diving Instructor Trainer with numerous dive training agencies. He owned/managed dive shops, dive resorts, and charter boats in Canada and the USA. He’s been on the Board of Directors of DEMA. He brings with him valuable experience from other industries, including sporting goods manufacturing, radio & TV broadcasting, railroads & transportation, digital marketing agencies, and education. Darcy is an engineer, radio announcer, and author.
The Business of Diving Institute (BODI) is the brainchild of Darcy Kieran. It started in September 2000, shortly after Darcy purchased his first dive shop. At the time, he was in charge of sales for the largest division of a multi-billion dollar international transport company, and he could not understand the lack of training available to his dive store staff. And even less, the lack of dive industry market data. There were numerous dive training agencies ready to support teaching scuba divers and dive instructors, but nobody was providing sales and management training — or any other form of staff training — tailored to the dive industry. It’s to address these issues that The Business of Diving Institute was born.

Frédéric Swierczynski

Frédéric has been a French explorer and cave diver for 30 years.
He travels around the world in numerous video productions and documentaries, as well as exploring caves, wrecks, scientific research and mapping.
The highest peaks in the world or the lowest sumps underground are the answer to his curiosity.
Frédéric also likes small, “difficult” dives since he has just broken the Guinness world record for “the deepest cave dive in the world” by diving in an incredible cave dive to a depth of 308 m in November 2024.
We’ll hear about this dive, his ideation and preparations for the fair from him during this upcoming festival.

Gareth Lock

Gareth Lock is the owner & founder of The Human Diver, an organisation formed to bring human factors knowledge, experience and practice from high-risk domains and academia into the sport of diving. Since January 2016 when he formed the company, he has taught hundreds of people in face-to-face classes around the world and thousands via online and webinar-based programmes. He has published Under Pressure: Diving Deeper with Human Factors, the only textbook that looks at this topic and in May 2019, released ‘If Only…’ which looks at a tragic diving accident through the lenses of human factors and a Just Culture. Over the last 3 years he has also led two reviews of fatal military diving accidents on behalf of Defence departments, applying systems thinking and human factors.
Recognising that the need for human factors is greater than one person can deliver, he has also trained ten instructors to deliver Human Diver materials around the globe and is working with two agencies to incorporate human factors concepts and tools into instructor development and diver training materials.

Stefan Panis

Stefan started diving at the age of 6 through his father. In 1992 he did his first “official” course. Since then he moved on to doing courses like nitrox and trimix, and he started diving an Inspiration rebreather in 2009 and Started photographing in 2013.
Meanwhile, he developed a great interest in wrecks and researching the history of the wrecks in the archives.
He spent many dives on wrecks in the North Sea (this year he was there when a virgin VOC ship from 1661 was found, and they are pushing to get a TV documentary done in 2022), the English Channel, where he is part of the expedition-team which has located and identified many shipwrecks, and abroad in Sardinia, Portugal, and Cuba just to name a few. He was involved in different successful expeditions searching for new wrecks, like the identification of the 1852 “Josephine Willis”.
In 2014 he also obtained his full cave CCR certificate.
Since then, Stefan has participated in many cave dives in Sardinia, France, and Spain, and he has become a “specialist” in looking for new Belgian mine sites, and he is photo-documenting them often with breathtaking pictures!

Stefan has written more than 50 articles for international magazines as well as several books.

Xavier Meniscus

Xavier Méniscus a French cave explorer, stands among the elite few who consistently venture into the abyss, pushing the boundaries of subterranean exploration. His remarkable feat? Descending to unfathomable depths, he holds the record for the deepest cave dive—a staggering 312 meters below the Earth’s surface at Font Estramar in 2023.
Trained at the Institut National de la Plongée Professionnelle (INPP) in Marseille, Xavier’s journey began as a military combat diver and later as a commercial saturation (SAT) diver with COMEX. His fascination with cave diving ignited in 2000, while still a SAT diver. Since then, he has explored numerous caves worldwide, including the Goul de la Tannerie in France, Pozo Azul in Spain, and Boesmansgat in South Africa.
Xavier’s unique approach to deep cave exploration transcends mere records. For him, it’s not about chasing depths; it’s about the relentless pursuit of the unknown. His motivation lies in exploration, not accolades. He shuns the Guinness record, emphasizing that exploration matters more than any numerical achievement. Xavier’s physiological resilience and extensive knowledge, gained from military, commercial, and research diving, equip him to navigate the challenges of sub-200 meter dives with precision and purpose.
Recently, he authored a book titled “Les mystères de l’eau en pays Gervanne entre l’émergence de Bourne et les Fontaigneux” (The Mysteries of Water in Gervanne Country: Between the Emergence of Bourne and the Fontaigneux), providing insights into his captivating underwater adventures. Xavier Méniscus exemplifies the spirit of exploration—one that transcends depths and embraces the enigma of hidden realms beneath our feet.
