"I do not know if these are the views of Saint Exupery or Mermoz who gave me the desire to know the places they had developed their image and feelings they described in their books ... But need to join Brazil in flight on a microlight led me into one of the most dangerous adventures that I have been given to achieve "



"After 15 years traveling the oceans on my sailboat charter and my big multihull racing, following a trail of 350 000 miles and several dozen Atlantic crossings, I always run to the far horizon curves continue fleeing constantly behind the waves. Atlantic, Mediterranean, Caribbean, Pacific, Indian are all maritime areas that have haunted and that always attract me with the same force! "

1998 - Mission Oxygen: under the indian ocean surface

Difficult experience that opened on the knowledge of the oceans in general and especially pelagic world. Ocean Observing an operation should be alert to the general public.

Crossing the Indian Ocean in 1998 in an underwater habitat drifting at -7m depth.


"Pollution, fishing pressure, climatic, are phenomena that destroy the balance ocean. Yet the future of humanity is played there in the deep blue sea as the phyto plankton produces 80% of our oxygen. More and more awareness raised against the abuses of our industrial society against this environment which should remain intact ... "

Test in situ in the port of Le Havre.

Difficulties encountered:
Weather anormally bad for the season (El Nino year)
Ruptures of the suspension of the underwater habitat (resistance 200 tons), and sinking of the underwater habitat after 13 days of drift.

Results, Advances in knowledge:
Observations made in marine biology at 65%
Drawing planktonic made to 60%
Experience leading (following the sinking of Ocean Observing) the design of new underwater habitats.



Ocean "My relationship with water and ocean is truly carnal.”

Born in the depths of the Champagne countryside, nothing predisposed to do that Guy Delage will love the ocean dumping ... yet it is one of them who will make known at 18, crossing the Channel by swimming alone and without assistance...
