Ahmed Gabr
Ahmed Gabr has an extraordinary story that no one else on this ocean planet can tell. It is a story that deepens the understanding of man in the underwater world and how he explored that unknown deepest space.
On 18 September 2014, Ahmed Gabr marked the diving history when he used open-circuit scuba to dive to the depth of 332.35 metres in record time, 12 minutes! Solo, in the pitch-dark cold water and crushing pressure, he met the challenge, but the celebrations would have to wait; surviving the 13+ hour journey back up to our world involved following his strict decompression schedule of graduated stops and breathing from 92 mixed gas tanks.
The rest of us mere mortals watching were left astonished and wondering… “How did he do it? Why did he do it?” and “what type of person does this?” Authenticity is what makes Ahmed Gabr exceptional, and backed by his training as a Special Forces Officer, Combat Diver and Technical Diving Instructor, he was already a strong performer in individual and team contexts. Ahmed understood that this high-stakes mission required an effective team that would harness the expertise and talents of diverse people, generating the synergy necessary to challenge the previous long-standing record achieved in 2005.
Andrew Marriott
Andrew is a long time diver, photographer and writer. Originally from the USA, he has since lived across the Pacific, Asia, and Europe. While living on the island of Guam he devoted himself full time to the ocean, helping many new divers fall in love with the water while working as an instructor and enthusiastic underwater photographer. After much encouragement from his friends and students, he devoted himself full time to taking and sharing his images and writing about diving.
It took time and patience, but within a few years his photos and writing were appearing in dive and travel magazines around the world. To date he has written around 100 articles, four books, and had his photos and videos used in various media outlets on a regular basis. Along with the publishing work came invitations to speak at major dive shows across Asia, Europe, and North America. To this day Andrew is a regular speaker at major dive events; having spoken at many shows from Beijing to Singapore to the United States, and pretty much everywhere in between.
The next logical step for him was to start a media production and publishing company that focused on diving and adventure travel. Fata Morgana Media was born in 2016 and it currently has six titles in publication and thirteen more in production. The writers and photographers for these books are from around the world and feature the most recognizable names in the business. Currently he lives in Germany with his awesome wife Dalice and two daughters Elly and EJ “Doomy”.
Armando Ribeiro
Diver since 1999, specialized in underwater photography and video, has won several national and international awards.
The taste for deep dives, unexplored wrecks and caves, lead Armando Ribeiro to create the 1st team of technical divers that use closed circuit rebreathers (CCR) in Portugal. Created in 2004/2005 the In-Silence Dive Team has as main objectives the development of CCR diving, the exploration off deep shipwrecks and caves on the Portuguese coast and the participation in international diving expeditions. Armando quickly became one of the first serious advanced expedition divers in Portugal, taking part in numerous adventures with some of the world’s best technical divers.
His most recent project aims to explore, obtain cave’s cartography and capture in video the biggest springs in Portugal. This exciting adventure was recently renewed by the discovery of new galleries that open the door to new challenges due to the greater depts and distance that can be achieved. The expeditions and projects impact, through the publication of articles in diving magazines and the national and international public projection of their videos, had a strong recognition in the national diving community, being already a reference in all expos and events related to technical diving.

Jeff Lindsay
Growing up on the shores of Great Lakes fostered a natural curiosity of the unexplored for Jeff Lindsay; learning to dive in 1990 lead to a lifelong desire to visit and photograph the unknown and forgotten.
With an almost limitless number of shipwrecks nearby, a natural progression into technical diving was required for the more remote and deeper locations; photography was a way for him to bring the experience to individuals who were not able to visit these challenging sites.
He’s been invited on numerous expeditions as team photographer and his biggest thrill is visiting a wreck or cave and capturing some, small part of its essence in a photograph

Marcus Blatchford
I learnt to dive in 2008 with my local club. Photography & diving have gone hand in hand – I acquired my first underwater camera during the course! I have always tried to set my sights high and quickly moved from recreational to tek diving, then onto CCR. In 2015 I qualified as a HSE Scuba commercial diver.
In 2016 I was introduced to photogrammetry – something that completely changed my direction and drive. Starting with attractions in my local quarries, I then moved onto shipwrecks scanning many in the waters around Malta. I then turned my focus from not only small attractions in quarries but to the entire site – both above and below the water level. The Vobster Photogrammetry Project is ongoing and pushing the technology we have to hand to the limits.
In 2019 I joined Pete Mesley’s Lust4Rust in a project to scan and model all of the wrecks of Truk Lagoon. This idea is being rolled out across the world to create a database of our favourite wrecks – which all have a limited lifespan – so they may be kept forever.

Paulo Costa
Paulo Costa took his scuba diving course in 1995 and started doing is own research on naval disasters shortly after, when he realized hardly anyone knew how to answer his questions about shipwrecks and their identities.
As a History graduate, he has since then focused his research on contemporary shipwrecks in Portuguese waters, mainly from the Age of Steam and both world wars. He is interested in the ships’ identification and history and how shipwrecks, as underwater cultural heritage, relate with memory, local and oral history, and the communities of users of the sea, like fishermen and scuba divers. He firmly believes that the research for shipwrecks, its study, preservation and dissemination of results must engage the local communities.
Certified as an open circuit trimix diver his interest in iron and steel shipwrecks has led him to dive in places like Scapa Flow, Gibraltar, Malta or Cyprus, among other spots.
At Diving talks 2021 he will present the result of his research about the first ship to sink in Portuguese waters due to the collision with a German mine in 1916, a shipwreck that today lays at the Lisbon’s harbour entrance, 80 meters deep.
