He was a member of teams that were first to dive and identify three historically significant deep shipwrecks in Australia and New Zealand, including one in 2002 which was the deepest wreck dive undertaken at the time. He was conferred Fellowship of the Explorers’ Club of New York in 2006, and was the Rolex Diver of the Year in 2015.

Teresa Amaro

Teresa Amaro is a deep-sea ecology researcher who adopts a holistic view of Marine Sciences and uses a multidisciplinary approach to solve scientific problems. Teresa has a degree in Biology from the University of Porto in Portugal (1998) and a PhD in Environmental Sciences from Wageningen University in The Netherlands (2005).
Since 1998 she has acquired an extensive experience in seagoing (over 50 cruises) and sampling the seafloor using many different techniques such as Remote Operated Vehicles, man-submersibles, landers, sediment traps, corers, trawlers and especially in-situ experiments. In 2013, she had the chance to dive to 5262 m in the Pacific Ocean using SHINKAI 6500.
Teresa has been a diver since 1996, but only in 2017 she became an Open Water Instructor from both SSI and CMAS. As she has an extensive admiration for the deep sea, during Covid pandemic, she became a rEvo Decompression Diver.
Teresa has only used recreational diving as a hobby, but currently, she is leading a project in Cabo Verde islands, where she will combine both deep-sea instrumentation and diving (recreational and technical).

Tom St George

Tom discovered a passion for diving over 20 years ago after emigrating from the UK to New Zealand. A decade later, the wanderlust struck again but with renewed force, motivating him to quit his office job and travel the world. When he settled on the Caribbean coast of the Yucatán Peninsula it was in cenotes that his dual obsessions of scuba diving and photography truly came together. He is best known for his award-winning images of the cenotes and underwater caves which have been published worldwide. He now works full-time as a professional photographer as well as offering underwater photography coaching and group workshops.
