On July 1, after about a year of preparation and planning, Members of the Swedish
Historical Diving Society and the Royal Institute of Technology Diving Club,
performed a series of Hydrox Dives in memory of the great innovator and diver, Arne
Zetterström, who was accidentally killed during the ascent from his record dive with
Hydrox in Aug 1945.
The memorial dives were performed using the same breathing mixture of 96%
Hydrogen and 4% Oxygen as was developed and tested by A Zetterström in the
1940's. The dives were made to a depth of 40m, just deep enough to be able to use
the Oxygen lean gas mixture.
