The Team

Edd Stockdale

Edd began his diving career at the early age of 12 in the North Sea off of Scotland and has been diving ever since. He completed a degree in marine zoology and worked for many years as a researcher with various institutions publishing in the field of physiology and biophysics, for which he won the 2008 French Academy of Science Jouvance Medal in Marine Biology.


He decided in around 2008 to head into full time diving and moved to SE Asia where he has been working in both the recreational diving industry, educational institutions and research stations in many capacities.

In recent years Edd has been concentrating predominately in both technical and scientific diving, combining the two of the purposes of research expeditions. He has worked in the capacity of Dive Safety Officer for the University of Oxford, University of Essex and University of Malta on various expeditions. In these roles he has helped develop undergraduate field work training programs, application of rebreathers to ecological research in the mesophotic zone and help successful expeditions looking at un-dived wrecks.

With thousands of dives in a vast array of environments Edd is an instructor and instructor trainer for multiple agencies he spends much of his time training people around the planet, while also writing training manuals for technical agencies and presenting at diving conferences. He is also a Training Advisor for RAID.

In 2016 he was nominated for the Eurotek Discovery Award for his work in wreck exploration.

Generally when not working in the field he will be found diving in various areas of the world exploring new caves or diving new wrecks while being an outspoken advocate for an improvement in the level of training and recruitment of younger divers within the technical diving world.

He is a member of The Explorers Club

Tiffany Norberg – Technical Team


Tiffany joins the team from Sweden to offer both technical diving education and expedition support.

Having spent most of her diving career in Scandinavian waters, her expertise is in cold water diving and deep wreck exploration. Her background is in designing training programs for athletes with more recent times seeing her concentrating on applications of this to dive exploration.

Her great passion is her JJ CCR and wreck diving, though she is happy to join pretty much any dive and share her passion in the sport, both experienced divers as well as newer members of the community.

She is a member of the Baltic wreck exploration team Badewanne and has presented on the subject at diving events and shows.


Francesco Colona – Instructor

Francesco is a RAID recreational instructor and scientific diver based in Linköping. He joined our team in 2020.

His passion for diving started at the doorstep of his southern Italian family home. After a detour in the Netherlands, in 2017 he discovered the cold waters of Scandinavia. Here he continued his technical diving training. Francesco works at the University of Linköping (Sweden) as a researcher where he follows his interest for the environment by studying strategies of carbon emission reduction in Swedish cities.

Francesco combines his research background and love for diving on the marine research station on Hoga Island, Indonesia, as a scientific diver and divemaster.
